Between 1972 and 1987, 43 patients underwent isolated mitral valve replacement with mean pulmonary arterial pressures greater than 50 mmHg. The valve disease was stenosis in 13 cases, regurgitation in 15 cases and mixed mitral valve disease in 15 cases. Forty-one patients (95 %) had invalidating cardiac failure (Stages III and IV of the NYHA Classification). The hospital mortality was 2.3%. Thirteen patients died during follow-up, 8 of cardiac failure, 3 of sudden death and 2 died of non-cardiac causes. The 8 year actuarial survival was 82 +/- 7% with an average postoperative follow-up of 96 +/- 41 months. No patients were lost to follow-up. Eighty six per cent of survivors (25/29) are asymptomatic or paucisymptomatic. Doppler studies were performed in 22 patients, showing normal prosthetic function in 18 cases and an obstructive prosthesis in 4 cases. Seventeen patients had tricuspid regurgitation showing normal pulmonary artery systolic pressures in 9 cases and less than 55 mmHg in 5 cases. On average, systolic pulmonary artery pressure fell from 88 +/- 11 mmHg before to 33 +/- 9 mmHg after surgery (p = 0.01). These results show that severe pulmonary hypertension is not prohibitive for mitral valve replacement. The long-term results are good with functional improvement and reduction of pulmonary hypertension. 相似文献

Progression of isolated tricuspid regurgitation late after mitral valve surgery for rheumatic mitral valve disease 总被引:6,自引:0,他引:6
BACKGROUND AND AIMS OF THE STUDY: Severe tricuspid regurgitation (TR) may develop late after mitral valve surgery without significant mitral stenosis, regurgitation and other causes of left heart failure. The study aim was to investigate severe isolated TR late after mitral valve surgery for rheumatic mitral valve disease. METHODS: A total of 208 patients who underwent mitral valve surgery (valve replacement in 121, commissurotomy in 62, valvuloplasty in 25) was investigated. The mean (+/-SD) follow up was 13+/-6 years. Severe isolated TR was defined clinically by elevated venous pressure, and echocardiographically by grade 4+ TR without significant mitral stenosis, regurgitation, other causes of left heart failure, pulmonary hypertension or rheumatic tricuspid valve. RESULTS: Severe isolated TR was identified in 30 patients (14%) at four to 24 years after mitral valve surgery. All patients had atrial fibrillation. Of these patients, 23 had medical treatment and seven had tricuspid valve surgery. Three of the medically treated patients were in NYHA class IV and died from multiple organ failure at three to seven years after severe TR was diagnosed. Among surgically treated patients, four were in NYHA class IV and had postoperative complications (one early death, one late death), while three NYHA class II/III patients had very few postoperative complications. CONCLUSION: Severe isolated TR was detected in 14% of patients after mitral valve surgery. It is important to detect patients with progressive heart failure and to indicate earlier reoperation in order to prevent significant late mortality. 相似文献

Thirty-four patients underwent isolated aortic valve replacement with mean pulmonary artery pressures greater than 40 mmHg between 1972 and 1988. The aortic valve disease was stenotic in 10 cases, regurgitant in 14 cases and mixed in 10 cases. Thirty patients (88%) had invalidating cardiac failure (NYHA Classes III and IV). The mean preoperative ejection fraction was 44 +/- 15%. The hospital mortality was 17.6%. Ten patients died secondarily, five with terminal cardiac failure. The 5 year actuarial survival was 70 +/- 16%; the 10 year survival was 60 +/- 18% with an average follow-up of 115 +/- 61 months. None of the patients was lost to follow-up. Fifteen of the 18 survivors (83%) are asymptomatic or pauci-symptomatic after a follow-up of 126 +/- 62 months. Doppler echocardiography (n = 12) showed normal prosthetic valve function in 11 cases and aortic regurgitation in 1 case. Eight patients had tricuspid regurgitation with pulmonary artery systolic pressures less than 30 mmHg in 6 cases and between 30 and 40 mmHg in 2 cases. Severe pulmonary hypertension is therefore a poor early postoperative prognostic factor in aortic valve replacement surgery due to the associated left ventricular dysfunction. However, the long-term results are satisfactory: clinical improvement is usually related to a reduction of pulmonary hypertension. 相似文献

In this series, the effect of replacement of the mitral valve was examined in 86/900 (9.6%) patients who had developed moderate functional tricuspid regurgitation, secondary to rheumatic mitral valvar disease. These patients were subdivided according to the severity of pulmonary hypertension and impairment of right ventricular function. Forty-six patients presented with severe pulmonary hypertension and 40 patients had moderate pulmonary hypertension (mean main pulmonary arterial pressure: 78 +/- 14 mmHg vs 41 +/- 6 mmHg; P less than 0.05). The latter had more advanced disease, greater impairment of right ventricular function and dilatation of the right heart chambers. Functional tricuspid regurgitation regressed in 38/42 survivors with severe pulmonary hypertension and persisted or progressed significantly in 22/34 survivors with impaired right ventricular function despite successful replacement of the mitral valve. The latter underwent replacement of the tricuspid valve (n = 16) or tricuspid annuloplasty (n = 6), at a mean interval of 44 +/- 4.4 months after replacement of the mitral valve, which resulted in 8/22 (23.5%) early deaths. Functional tricuspid regurgitation is more likely to persist in patients with advanced right ventricular failure. Tricuspid valvar competence should be restored in these patients at initial replacement of the mitral valve. 相似文献

Echocardiography allows the detection of vegetations and estimation of valvular dysfunction in patients with infective endocarditis. The value of echocardiographic findings in predicting cardiac and other vascular complications in infective endocarditis is not well understood. Identification of high-risk patients and early surgery may improve their prognosis. The authors reviewed echocardiographic findings and related them to the development of congestive heart failure, systemic embolism, and the need for surgery or the risk of death without surgery in patients with infective endocarditis. There were 125 episodes of endocarditis in 114 patients (84 episodes [67%] in men) with a mean age +/- standard deviation of 37 +/- 7 years. Vegetations were detected by echocardiography on at least 1 valve in 87 episodes (70%); on the mitral valve in 36 episodes (29%); on the aortic valve in 21 episodes (17%); and on the tricuspid valve in 45 episodes (36%). Severe aortic regurgitation was present in 9 episodes (7%) and severe mitral regurgitation in 4 instances (3%). In 12 of 21 episodes (57%) of vegetations on the aortic valve compared with 15 of 104 patients (14%) without vegetations on the aortic valve (p < 0.001), and in 8 of 9 instances (89%) of severe aortic regurgitation compared with 19 of 116 episodes (16%) without severe aortic regurgitation (p<0.00001), the patients developed congestive heart failure. In 18 of 55 episodes (33%) of vegetations on the aortic/mitral valve compared with 17 of 70 episodes (25%) without vegetations on the aortic valve/mitral valve (p = NS), the patients developed systemic embolism. In 13 of 21 episodes (62%) of vegetations on the aortic valve compared with 19 of 104 episodes (19%) without vegetations on the aortic valve (p < 0.001), and in 8 of 9 episodes (89%) of severe aortic regurgitation compared with 24 of 116 episodes (21%) without severe aortic regurgitation (p < 0.00001), the patients either had surgery or died without surgery. Echocardiographic findings do not reliably predict the risk of systemic embolism in patients with infective endocarditis. Vegetations on the aortic valve and severe aortic regurgitation detected by echocardiography predict a high risk of developing congestive heart failure, and for the combined outcome of requiring surgery, or dying without surgery in infective endocarditis. Early surgery may improve the outlook for survival of these patients. 相似文献

The incremental risk of coronary bypass surgery was analyzed in 718 patients undergoing mitral valve replacement between 1971 and 1983. Ninety-eight patients (14%) had significant coronary artery disease requiring coronary bypass surgery. In 70 of these patients, the origin of the mitral valve disease was nonischemic, whereas 28 patients had ischemic mitral regurgitation unsuitable for conservative valve surgery. There were six operative deaths (9%) and four perioperative myocardial infarctions (6%) after mitral valve replacement and coronary bypass surgery for nonischemic mitral valve disease. Operative mortality was related to low output cardiac failure before operation or perioperative myocardial infarction. Actuarial curves predict survival (+/- standard error) of 55 +/- 7% at 5 years and 43 +/- 8% at 10 years. Preoperative functional class was the only significant predictor of long-term survival in this group (p less than 0.05). The actuarial survival of the 620 patients without coronary artery disease who underwent mitral valve replacement alone was 63 +/- 3% at 10 years. This was significantly better than that of the 70 patients who underwent mitral valve replacement and coronary bypass surgery for nonischemic mitral valve disease (p less than 0.001). Conversely, 5 year survival of the 28 patients with ischemic mitral regurgitation was 43 +/- 10%. This confirms the negative detrimental effect of an ischemic origin of mitral valve disease on survival after mitral valve replacement and coronary bypass surgery (p less than 0.0001). 相似文献

Objectives, This study examined the association between the presence of tricuspid regurgitation and immediate and late adverse outcomes in patients undergoing balloon mitral valvuloplasty.Background. Significant tricuspid regurgitation has an adverse impact on morbidity and mortality in patients undergoing mitral valve surgery for mitral stenosis.Methods. We studied 318 consecutive patients (mean [± SD] age 54 ± 15 years) who underwent ballon mitral valvuloplasty and had color Doppler ecnocardiographic studies before the procedure. Patients were classified into three groups: 221 with no or mild (69%), 60 with moderate (19%) and 37 with severe (12%) tricuspid regurgitation. Clinical follow-up ranged from 6 to 62 months.Results. Before mitral valvuloplasty, increasing degrees of tricuspid regurgitation were associated with a smaller initial mitral valve area (p < 0.05), higher echocardiographic score (p < 0.05), lower cardiac output (p < 0.01) and higher pulmonary vascular resistance (p < 0.01). Although the initial success rate did not differ significantly between groups, patients with a higher degree of tricuspid regurgitation had less optimal results, as reflected by a smaller absolute increase in mitral valve area (1.02 vs. 0.9 vs. 0.7 cm2, p < 0.01). The estimated 4-year event-free survival rate (freedom from death, mitral valve surgery, repeat valvuloplasty and heart failure) was lower for the group with severe tricuspid regurgitation (68% vs. 58% vs. 35%, p < 0.0001). At 4 years, 94% of patients with mild tricuspid regurgitation were alive compared with 90% and 69%, respectively, of patients with moderate or severe tricuspid regurgitation (p < 0.0001). Cox proportional analysis identified tricuspid regurgitation as an independent predictor of late outcome (p < 0.001).Conclusions. Patients with mitral stenosis and severe tricuspid regurgitation undergoing mitral valvuloplasty have advanced mitral valve and pulmonary vascular disease, suboptimal immediate results and poor late outcome. 相似文献

To investigate right ventricular function in mitral valve disease, biplane cineventriculograms of the right and left ventricle were performed in 96 patients-35 with mitral stenosis, 26 with mitral regurgitation, 12 with combined mitral valve disease, 14 with mitral stenosis and tricuspid regurgitation, and nine with mitral regurgitation and tricuspid regurgitation, compared to 18 normals (N). Right ventricular enddiastolic volume index was moderately elevated in patients with mitral stenosis and concomitant tricuspid regurgitation (111.6 +/- 35.3 ml/m2, no significance compared to N: 95.9 +/- 21.8 ml/m2) and with mitral regurgitation and tricuspid regurgitation (107.9 +/- 45.1 ml/m2, no significance compared to N). A reduced right ventricular ejection fraction (RVEF less than or equal to 50%) was found in 40 of the 96 patients. Right ventricular ejection fraction was frequently reduced in patients with mitral regurgitation and tricuspid regurgitation (46.7% +/- 15.1%) and significantly reduced in patients with combined mitral valve disease (45.0 +/- 17.6%, compared to N: 58.0 +/- 7.1%, p less than 0.01). No significant correlations were found between right ventricular ejection fraction and left ventricular enddiastolic volume or left ventricular ejection fraction in patients with mitral valve disease. Moreover, right ventricular ejection fraction did not correlate with systolic pulmonary artery pressure, mean pulmonary artery pressure or mean pulmonary capillary wedge pressure. Local wall motion (mean systolic shortening) was determined for the anterior, anteroapical, and inferior segment in the RAO-projection and for the right ventricular free wall in the LAO-projection. 63% of the patients (n = 25) with reduced right ventricular function (RVEF less than of equal to 50%) showed local wall motion abnormalities, preferably in the anterior segment of the RAO- projection (48%) and the right ventricular free wall (30%).(ABSTRACT TRUNCATED AT 250 WORDS) 相似文献

Impact of atrial fibrillation on tricuspid and mitral annular dilatation and valvular regurgitation. 总被引:3,自引:0,他引:3
Xiaoyan Zhou Yutaka Otsuji Shiro Yoshifuku Toshinori Yuasa Hui Zhang Kunitsugu Takasaki Keiko Matsukida Akira Kisanuki Shinichi Minagoe Chuwa Tei 《Circulation journal》2002,66(10):913-916
To investigate the effects of atrial fibrillation (AF) on the mitral and tricuspid valves, the corresponding annular dilatation and valvular regurgitation were compared with 2-dimensional and Doppler echocardiography in 31 consecutive patients with lone AF and 28 normal controls. Mid-systolic mitral and tricuspid annular areas were measured from 2 diameters in 2 orthogonal apical echocardiograms. Percent (%) mitral regurgitant (MR) or tricuspid regurgitant (TR) jet area to the left or right atrial area was evaluated and % MR or TR jet area >20% was considered moderate or significant. Both the mitral and tricuspid annular areas in patients with lone AF were significantly larger compared with the controls (mitral: 9.5 +/- 1.2 vs 6.6 +/- 0.9 cm2, lone AF vs control, p < 0.01) (tricuspid: 12.0 +/- 2.0 vs 7.5 +/- 0.9 cm2, p < 0.01). The % increase in the annular area relative to the mean normal value was significantly greater in the tricuspid valve (44 +/- 18 vs 60 +/- 28%, p < 0.01). Moderate or severe MR was not observed and the incidence of moderate or severe valve regurgitation (% jet area >20%) was significantly higher in the tricuspid valve (0/31 vs 11/31, MR vs TR, p < 0.01) in patients with lone AF. The % TR jet area showed significant correlation with tricuspid annular area (r2 = 0.65, p < 0.001). Lone AF is associated with annular dilatation of both mitral and tricuspid valves, but the annular dilatation and valvular regurgitation are significantly greater in the tricuspid valve. 相似文献

BACKGROUND AND AIM OF THE STUDY: Clinical and echocardiographic results were investigated to evaluate mitral valve repair in patients undergoing coronary artery bypass grafting (CABG) for ischemic cardiomyopathy (ICM) with moderately severe mitral regurgitation (MR). METHODS: A total of 78 patients (21 women, 57 men; mean age 69.5 +/- 7.8 years) with ischemic mitral regurgitation underwent mitral valve repair and CABG. The mean left ventricular ejection fraction (LVEF) was 42.4 +/- 12.4%. Among the patients, 19 (24.4%) had preoperative congestive heart failure (CHF). This surgery constituted a second such operation in five patients (6.4%). The MR was grade 3+ in 28 patients (35.9%) and 4+ in 50 (64.1%). The mean number of grafts was 3.6 per patient. RESULTS: Hospital mortality was 11.5% (n = 9). Risk factors for early mortality were preoperative NYHA class > or = III (p = 0.014), preoperative heart failure (p <0.001) and reoperation (p = 0.002). The five-year survival was 82.6 +/- 5.9%, and freedom from grade > or =2+ MR was 93.1 +/- 4.1%. Postoperatively, 66 patients (89.6%) were in NYHA class I and seven (9.4%) in class II, demonstrating a statistically significant improvement (p = 0.03). Late echocardiography showed a significant improvement in LVEF (from 42.4 +/- 12.4% to 51.7 +/- 10.9%; p = 0.01) and a reduction in pulmonary artery pressure (from 37.6 +/- 11.9 mmHg to 29.3 +/- 7.4 mmHg; p = 0.004). CONCLUSION: It is concluded that in patients with ICM, mitral valve repair combined with CABG provides a dramatic improvement in ejection fraction and in CHF, with excellent long-term survival, even in patients with a low LVEF. 相似文献

Can two-dimensional echocardiography and Doppler color flow mapping identify the need for tricuspid valve repair? 总被引:4,自引:0,他引:4

Tricuspid regurgitation severity was assessed preoperatively with Doppler color flow mapping and these assessments were compared with surgical findings in 90 patients undergoing mitral or aortic valve replacement, or both. Group I (n = 52) required tricuspid valve annuloplasty because tricuspid regurgitation was judged intraoperatively to be severe; in Group II (n = 38), tricuspid valve annuloplasty was not performed because tricuspid regurgitation was judged intraoperatively not to be severe. With use of the apical four chamber and parasternal short-axis imaging planes, the severity of tricuspid regurgitation by Doppler color flow mapping was assessed by comparing the maximal area of tricuspid regurgitant signals with the right atrial area taken in the same frame in which the maximal tricuspid regurgitant signals were noted. This ratio was found to be greater than or equal to 34% (mean 50.2 +/- 11.8%) in 50 (96%) of 52 patients in Group I and less than 34% (mean 27.5 +/- 6.9%) in 36 (95%) of 38 patients in Group II (p less than 0.001). The maximal diastolic tricuspid anulus diameter measured with the same two-dimensional imaging planes was greater than or equal to mm/m2 body surface area (mean 26.7 +/- 5.2 mm/m2) in 46 patients (88%) in Group I and less than 21 mm/m2 (mean 17.8 +/- 2.5 mm/m2) in 36 patients (95%) in Group II (p less than 0.001).(ABSTRACT TRUNCATED AT 250 WORDS) 相似文献

BACKGROUND AND AIMS OF THE STUDY: Patients with symptoms of right heart failure due to severe tricuspid regurgitation following a prior operation on left heart valves present a difficult problem. The outcome of tricuspid surgery in this setting is not well defined. We describe a single-center experience of isolated tricuspid valve surgery after prior left heart valve surgery, and analyze potential risk factors for a poor outcome. METHODS: Thirty-four patients who underwent isolated tricuspid valve operation for severe tricuspid regurgitation following prior valvular surgery for left-sided valve disease between 1980 and 1997 were identified. Charts were reviewed for clinical, echocardiographic, catheterization and surgical data. Follow up of survivors was conducted by telephone to ascertain functional status. RESULTS: Three patients died in hospital (early mortality rate, 8.8%). At a follow up of 71 +/- 39 months, 13 patients were alive and 21 reached an end-point (three cardiac reoperations, 18 deaths). Event-free actuarial survival at five years was 41.6 +/- 9.2%. Patients who were alive at follow up had a mean NYHA functional class of 2.1 +/- 0.6 compared with 3.4 +/- 0.5 preoperatively; 85% of survivors were symptomatically improved. Predictors of poor outcome were: increased age at the time of tricuspid surgery (p = 0.0007) and higher number of prior cardiac operations (one versus two or three, p-value 0.01, relative risk 3.4). Pulmonary artery systolic pressure, left ventricular ejection fraction, right ventricular function and size, annulus diameter, tricuspid valve pathology, and valve replacement versus repair were not predictive of outcome. CONCLUSIONS: Isolated tricuspid valve surgery for severe tricuspid regurgitation following prior surgery for left-sided heart valve disease can be performed with acceptable early mortality. There remains a high late mortality that is predicted only by age and the number of previous cardiac operations. However, in this selected group of severely symptomatic patients, significant improvement in symptoms are achieved in the survivors. 相似文献

Tricuspid regurgitation late after mitral valve replacement: clinical and echocardiographic evaluation 总被引:11,自引:0,他引:11

BACKGROUND AND AIM OF THE STUDY: Significant tricuspid regurgitation (TR) can contribute to increased morbidity and mortality in patients after mitral valve replacement (MVR), both in the immediate and late postoperative period. The aim of this study was to evaluate the prevalence and the clinical importance of TR late after MVR, as assessed both clinically and echocardiographically. METHODS: The study group comprised 65 patients (39 women, 26 men; mean age 61+/-12 years) with rheumatic heart disease who had undergone MVR without tricuspid valve surgery between one and 30 years (mean 11.3+/-8 years) before their last clinical examination. All patients underwent a complete color-Doppler echocardiographic examination. The predominant presurgical mitral lesion was stenosis in 44 patients and regurgitation in 21. The severity of the tricuspid valve disease was assessed echocardiographically using color-Doppler flow images and flow direction in the inferior vena cava or hepatic veins, and by clinical evaluation. RESULTS: Echocardiography revealed significant late TR in 44 patients (67%), which was moderate in 16 and severe in 28, and evident on physical examination in 24 cases (37%). Age (relative risk (RR) = 1.1; C.I. 1-1.1) and female sex (RR = 1.8; C.I. = 1.0-3.2) were identified as statistically significant predictors for late clinical TR development, but only age was found as a statistically significant predictor for echocardiographic TR development. An elevated RR for organic TR and predominant mitral regurgitation was found. In contrast, pre- and postoperative pulmonary artery pressure, predominant mitral lesion, prosthetic valve gradient and regurgitation were similar in patients with and without late TR. CONCLUSIONS: Significant TR diagnosed by echocardiography late after MVR is common, and clinically evident in more than one-third of patients. Therefore, a lower threshold for tricuspid valve repair should be considered when mitral valve surgery is carried out. 相似文献

BACKGROUND AND AIM OF THE STUDY: Mitral valve regurgitation (MVR), occurring as a result of myocardial ischemia and global left ventricular (LV) dysfunction, is predictive of poor outcome. The study aim was to assess the feasibility of mitral valve surgery concomitant with coronary artery bypass grafting (CABG) in patients with ischemic MVR grade II-III and impaired LV function. METHODS: Between January 1996 and July 2000, 99 patients with grade II and III ischemic MVR and LV ejection fraction (LVEF) 17-30% underwent either combined mitral valve surgery and CABG (group I, n = 49) or isolated CABG (group II, n = 50). LVEF (%), LV end-diastolic diameter (LVEDD; mm), LV end-diastolic pressure (LVEDP; mmHg), LV end-systolic diameter (LVESD; mm) respectively were 27.5+/-5, 67.7+/-7, 27.7+/-4 and 51.4+/-7 in group I versus 27.8+/-4, 67.5+/-6, 27.5+/-5 and 51.2+/-6 in group II. In group I, mitral valve repair was performed in 43 patients (88%) and replacement in six (12%). RESULTS: Preoperative data analysis showed no difference between groups. Five patients (10%) died in group I, compared with six (12%) in group II (p = NS). Within six months of surgery, LV function and geometry improved significantly in group I versus group II (LVEF, p <0.001; LVEDD, p = 0.002; LVESD, p = 0.003, LVEDP, p <0.001); only mild improvements were seen in group II. The regurgitation fraction decreased significantly in group I patients after surgery (p <0.001). Cardiac index increased significantly in groups I and II (p <0.001 and p = 0.03, respectively). In group I at follow up, four of six patients undergoing mitral valve replacement died, compared with five of 43 patients (11.5%) undergoing mitral valve repair (p = 0.007). At three years, the overall survival in group II was significantly lower than in group I (p <0.009). CONCLUSION: Both MV repair and replacement preserving subvalvular apparatus in patients with impaired LV function offered acceptable outcome in terms of morbidity and survival. Surgical correction of grade II-III MVR in patients with impaired LV function should be taken into consideration as it provides better survival and improves LV function. 相似文献

OBJECTIVE: To compare the sensitivities of Doppler echocardiography and cardiac catheterization in the diagnosis of severe valvular heart disease in patients requiring valve surgery. DESIGN: Retrospective analysis of Doppler echocardiograms and cardiac catheterizations. SETTING: Tertiary referral cardiovascular centre in a university setting. PATIENTS: Sixty-nine patients undergoing valve surgery between July 1988 and July 1990. RESULTS: The sensitivities of echocardiography and cardiac catheterization were 84 and 87%, respectively (P = 1.0) in 32 patients who underwent aortic valve surgery primarily for severe aortic stenosis; 83 and 67%, respectively (P = 1.0) in six patients with severe aortic regurgitation, and 100 and 85%, respectively (P = 1.0) in seven patients with combined severe aortic stenosis and regurgitation. The sensitivities of echocardiography and cardiac catheterization in 11 patients who underwent mitral valve surgery for severe mitral stenosis were 73 and 91%, respectively (P = 0.6) and 69 and 92%, respectively (P = 0.3) in 13 patients with severe mitral regurgitation. Sensitivities of echocardiography and cardiac catheterization in the diagnosis of severe tricuspid regurgitation in five patients who had tricuspid valve repair were 100 and 80%, respectively (P = 1.0). Two patients with severe aortic stenosis by echocardiography, but not by catheterization, did not undergo aortic valve replacement during valvular surgery; both required aortic valve replacement within two years of initial surgery because of heart failure. Four patients with severe tricuspid regurgitation identified by echocardiography did not have tricuspid repair; three had pulmonary hypertension and these patients had resolution of tricuspid regurgitation on follow-up. One patient with severe tricuspid regurgitation and absence of pulmonary hypertension required reoperation for tricuspid valve repair 10 months after initial operation. CONCLUSIONS: The sensitivity of echocardiography and cardiac catheterization in the detection of severe valvular lesions requiring surgery is similar. Discordant results should be reviewed carefully with knowledge of the inherent pitfalls of both techniques in order to ensure optimal patient outcome. 相似文献

BACKGROUND AND AIMS OF THE STUDY: The outcome of percutaneous balloon mitral commissurotomy (BMC) has been reported as poor in patients with prior surgical commissurotomy. The study aim was to evaluate immediate and long-term follow up results of BMC in patients with restenosis after surgical commissurotomy compared to patients with 'de-novo' mitral stenosis. METHODS: Between October 1988 and September 1999, a total of 1,027 patients underwent BMC. Of these patients, 169 (16.5%) were examined at 17+/-7 years (range: 2-33 years) after surgical commissurotomy (group 1), and 858 (83.5%) had de-novo mitral stenosis (group 2). RESULTS: Group 1 patients were older than group 2 patients (49.4+/-9.3 versus 47.3+/-9.6 years; p <0.05), and atrial fibrillation was seen more often in group 1 (53.9% versus 32.4%; p <0.005). Before BMC, mitral valve area (MVA) was similar in both groups (1.18+/-0.27 and 1.15+/-0.26 cm2 in groups 1 and 2 respectively; p = NS); following BMC, MVA was 1.82+/-0.3 and 1.93+/-0.40 cm2 respectively (p <0.05). Four patients (2.4%) from group 1, and 24 (2.8%) from group 2 required mitral valve replacement due to severe regurgitation (p = NS). Annual clinical and echocardiographic evaluation was completed for 950 patients (mean follow up 56.2+/-31.1 months (range: 12-132 months). Cardiac events defined as death, valve surgery or repeat BMC occurred in 16.0% of patients in group 1, and in 9.6% of those in group 2. At follow up of three, five and 10 years, actuarial event-free survival was 85.7+/-2.9%, 79.8+/-3.8% and 65.2+/-7.5% respectively in group 1, and 93.4+/-0.9%, 90.1+/-1.1% and 72.7+/-3.9% respectively in group 2 (log rank test, p = 0.02). Multivariate analysis showed MVA <1.5 cm2 after BMC, mitral regurgitation grade >2/4, Wilkins score >8, and mean transmitral gradient and left atrial mean pressure post BMC to be independent predictors of an adverse event occurring during follow up. CONCLUSION: BMC in patients with restenosis after surgical commissurotomy is an effective method of treatment, and may help to avoid valve surgery in most patients. 相似文献

BACKGROUND AND AIM OF THE STUDY: Recently published data suggest that prosthesis-patient mismatch is common after mitral valve replacement (MVR), and manifests as persistent pulmonary hypertension. The study aim was to determine the prevalence and severity of pulmonary hypertension after mitral valve surgery, including mitral valve repair, and to determine whether surgery type affects the prevalence of post-operative pulmonary hypertension. METHODS: Matched preoperative and > or =1 year postoperative Doppler estimates of right ventricular systolic pressure (RVSP) were evaluated in a cohort of 179 patients who underwent MVR or repair (33 after bioprosthetic valve replacement, 20 after mechanical valve replacement, 43 after physiological valve repair (predominantly for myxomatous disease), 78 after undersized annuloplasty for functional regurgitation, and five after repair of rheumatic stenosis). RESULTS: Patients undergoing repair of function mitral regurgitation had a lower left ventricular ejection fraction. The postoperative mean transmitral gradient was slightly higher for patients after bioprosthetic valve replacement (6.9 +/- 2.6 mmHg) compared to mechanical valve replacement (5.2 +/- 2.8 mmHg; p = 0.03), physiological repair (5.2 +/- 2.8 mmHg; p = 0.05), or repair of functional regurgitation (5.5 +/- 2.8 mmHg; p = 0.02). Pulmonary hypertension was common (present in 78% of patients before and 64% after surgery), and there were no significant differences between groups in the prevalence of postoperative pulmonary hypertension. The RVSP tended to decrease in all groups, but reached statistical significance only for patients undergoing bioprosthetic replacement (-9 +/- 24 mmHg; p = 0.04), mechanical replacement (-10 +/- 14 mmHg; p = 0.003) or physiological repair (-6 +/- 16 mmHg; p = 0.01). CONCLUSION: Pulmonary hypertension is common before and after mitral valve surgery. Although there were at least trends toward lower pulmonary artery pressures regardless of surgery type, significant decreases were noted only after MVR and physiological repair. A slightly higher postoperative mean transmitral gradient after bioprosthetic valve replacement may have contributed to postoperative pulmonary hypertension. The physiological repair of organic, non-rheumatic mitral regurgitation appears to offer favorable hemodynamics and a relatively low rate of postoperative pulmonary hypertension. 相似文献

The immediate post-operative results of conservative surgery were evaluated objectively in 31 children aged under 13 years referred to us for surgical correction of severe rheumatic mitral valve regurgitation. 16 patients had pure mitral regurgitation. In the others, lesions which required additional surgery were aortic regurgitation in 7 cases, tricuspid of the mitral valve and left ventricle was studied by two-dimensional TM-mode echocardiography. This examination was combined with a pulsed doppler study in search of a possible residual mitral regurgitation signal, with special attention to the depth at which it was recorded in the left atrium -- a semi-quantitative indication of the severity of residual leakage. Two mitral valve replacements were performed, and two early reoperations were needed for residual regurgitation developed between the 5th and 8th post-operative days. Three deaths occurred due to supra-systemic pulmonary arterial hypertension. The post-operative evaluation of mitral valvuloplasty results therefore involved 25 patients. In the absence of significant residual mitral regurgitation, two-dimensional echocardiography was inconclusive since the images obtained varied considerably according to the surgical procedures performed. There was a distinct reduction of end-diastolic diameters (43.5 +/- 5.9 versus 62.1 +/- 8.7 mm pre-operatively), reflecting the disappearance or marked decrease of the pre-operative ventricular volume overload consecutive to mitral regurgitation. The reduction of end-systolic diameters was also significant (31.2 +/- 6.7 mm versus 39.2 +/- 7.1 mm pre-operatively), though less pronounced than that of end-diastolic diameters, which explains the diminution observed in the percentage of fibre shortening, although the figures remained within normal limits (28.7 +/- 9.7 p. 100 versus 37.0 +/- 6.8 p. 100).(ABSTRACT TRUNCATED AT 250 WORDS) 相似文献

The present study examined the safety and immediate and late outcome of 12 patients with coexisting moderate (angiographic grade 2+) mitral regurgitation and significant subvalvular disease and/or calcified mitral valves (group 1) after percutaneous balloon mitral commissurotomy (BMC) and compared the results with 64 patients without these adverse valve features (group 2). BMC produced a significantly smaller echocardiographically determined mitral valve area improvement in group 1 compared with group 2 (from 0.7 +/- 0.2 cm2 to 1.3 +/- 0.3 cm2 vs. 0.8 +/- 0.2 cm2 to 1.7 +/- 0.4 cm2, respectively, p < 0.05). Similarly, compared with group 2, less patients in group 1 obtained an optimal valvuloplasty outcome defined as a 3 50% increase in mitral valve area or a final valve area of 3 1.5 cm2 without final 3 3 grade angiographic mitral regurgitation (75% vs. 95%, p < 0.05). There was, however, no severe (3 angiographic grade 3+) mitral regurgitation in group 1 compared with 1 in group 2 (p = NS). At a mean follow-up of 19 +/- 14 months, there were no deaths or strokes. Restenosis was noted in 4 patients; 3 in group 1, and 1 in group 2. We conclude that BMC is safe and effective in patients with pre-existing moderate mitral regurgitation and severe subvalvular disease and/or significant mitral calcification with minimal risk of creating severe mitral regurgitation. The valve area improvement was, however, substantially smaller and the restenosis rate higher than those without moderate mitral regurgitation and favorable valve anatomy. 相似文献

To study the long-term results of tricuspid valvuloplasty, pre- and postoperative (51 +/- 17 months) echocardiographic and catheterization data were collected from 51 patients (aged 59 +/- 9 years). Because of severe mitral stenosis all patients received a heterograft in the mitral position and underwent reconstructive tricuspid surgery with Carpentier rings. With regard to postoperative clinical outcome three patient groups were distinguished: 37 patients (group A) showed clear clinical improvement; in seven patients mild, and in three patients moderate tricuspid regurgitation persisted. A mild tricuspid stenosis of less than 4 mm Hg mean diastolic gradient was found in 11 patients. Patients in group B (n = 8) showed no clinical improvement, but there was persistence of moderate tricuspid regurgitation associated with nearly unchanged pulmonary hypertension in five patients and moderate tricuspid stenosis in two. Six patients (group C) showed deterioration of their clinical status; in two patients a severe degree of tricuspid regurgitation persisted, and four patients were first seen with a tricuspid stenosis with a mean diastolic gradient greater than 7 mm Hg. Analysis of postoperative data showed that tricuspid stenosis may develop during surgery in patients with slightly shrunken valve leaflets. Although the area of the anterior tricuspid leaflet was slightly underestimated, we found that long-term results of tricuspid valve annuloplasty with a Carpentier ring were encouraging. Doppler echocardiography for detection of tricuspid regurgitation and transvalvular pressure gradient showed results identical to hemodynamic data and is a suitable and sensitive method for evaluating postoperative results after tricuspid valve annuloplasty. 相似文献
