A case of pulmonary varices in a 24-year-old man with mitral regurgitation is reported. A brief summary of the literature on pulmonary varices associated with mitral valve disease is presented, with special reference to its etiology and surgical treatment. It is strongly suggested that production of varicosities of the pulmonary vein requires not only increased pulmonary venous pressure but also other local factors. If the patient has symptoms due to mitral regurgitation, operation for mitral valve disease is indicated. Direct operative intervention for the varices should not be performed. 相似文献

To compare the hemodynamic effect of vasodilator therapy on different regurgitant lesions, we infused sodium nitroprusside intraooperatively in 12 patients with mitral regurgitation and 15 with aortic regurgitation. During the critical period preceding establishment of cardiopulmonary bypass, both groups had developed intense vasoconstriction and cardiac decompensation. All demonstrated improved cardiac function with vasodilator therapy; however, the degree of improvement with nitroprusside differed in the two groups. Stroke volume increased 10 ml. per beat per meter squared in those patients with aortic regurgitation and only 6 ml. per beat per meter squared in those with mitral regurgitation (p less than 0.05). The percent increase in stoke volume induced by nitroprusside was inversely correlated to the preoperative left ventricular ejection fraction (r = 0.44, p less than 0.02). Patients with aortic regurgitation had lower preoperative left ventricular ejection fractions than those with mitral regurgitation (0.53 versus 0.63, p less than 0.02). Therefore, we conclude that patients with aortic regurgitation derived greater intraoperative hemodynamic benefit from unloading with nitroprusside, because they came to surgery with greater impairment of left ventricular contractility. Although nitroprusside improved cardiac function in both groups, only the patients with aortic regurgitation achieved normal pulmonary artery pressure (17 torr) and pulmonary vascular resistance (2.1 units) as a result of unloading. Those with mitral regurgitation continued to have pulmonary hypertension (28 torr) and increased pulmonary vascular resistance (3.9 units) despite vasodilator therapy. Thus the data suggest that patients with mitral regurgitation derived less hemodynamic benefit from intraoperative nitroprusside therapy because they were also limited by right ventricular dysfunction and a less responsive pulmonary vasculature. 相似文献

Two cases of cardiogenic shock and pulmonary edema due to acute, severe, silent mitral regurgitation are discussed. The mechanism for the mitral regurgitation was papillary muscle rupture in the setting of acute myocardial infarction. Echocardiography established the presence, severity, and cause of the mitral regurgitation and the associated hyperdynamic left ventricular function in the setting of cardiogenic shock. Transesophageal echocardiography is excellent for assessing the mitral valve in critically ill patients in whom transthoracic echocardiography may be inadequate or misleading. This allowed for emergency mitral valve replacement without prolonged attempts at medical stabilization. 相似文献

A 57-year-old woman was admitted to our hospital for the treatment of mitral regurgitation and giant bulla with severe pulmonary hypertension. A dobutamine-induced test performed preoperatively resulted in a decrease of the systolic pulmonary artery pressure by 30 mmHg. Subsequently, mitral valve replacement and bullectomy were performed concomitantly. The patient recovered from heart failure, and the pulmonary artery pressure clearly decreased during the perioperative period. This case report serves to demonstrate the effectiveness of performing a one-staged operation for mitral regurgitation and giant bulla with severe pulmonary hypertension. 相似文献

Williams syndrome is a genetic disorder associated with various cardiovascular abnormalities, most commonly supravalvar aortic stenosis and peripheral pulmonary stenosis. However, isolated severe mitral regurgitation necessitating surgical intervention is extremely rare. Here, we present the case of a 14‐year‐old child with Williams syndrome and isolated severe mitral regurgitation who underwent successful mitral valve repair. 相似文献

A 61-year-old woman with mitral valve regurgitation and pulmonary hypertension, was referred to us for surgical repair. Preoperative left ventriculography showed Sellers IV mitral valve regurgitation and high pulmonary arterial pressure: 103/31 (57) mmHg. The mitral valve was replaced with a phi 27 mm SJM mechanical valve. The postoperative residual pulmonary hypertension was successfully treated with nitric oxide gas, decreased significantly pulmonary arterial pressure, and the postoperative course was uneventful. Based on our experience, we think that nitric oxide gas may prove effective for residual pulmonary hypertension after a cardiac operation. 相似文献

Left atrial or pulmonary capillary wedge pressure V waves are used immediately after mitral valve replacement to evaluate valve competence. However, their correlation with hemodynamically significant regurgitation has not been established. Transesophageal echocardiography (TEE) was used to prospectively examine whether left atrial V waves represented significant mitral regurgitation in 11 patients undergoing mitral valve replacement. Left atrial pressure V waves were measured in the immediate postcardiopulmonary bypass period by direct cannulation of the right superior pulmonary vein and recorded on a paper chart recorder. In each patient, three evaluations of mitral regurgitation by Doppler TEE were made at 15-minute intervals. In 22 of 33 evaluations, left atrial V waves with peak V wave height more than 5 mm Hg above the mean left atrial pressure were present. However, only in 3 of these periods did transesophageal echocardiography show evidence of more than trace mitral regurgitation by pulsed Doppler and color flow mapping. As indicators of mild-to-severe mitral regurgitation diagnosed by TEE, left atrial V waves had a specificity for the three evaluation periods of 40%, 30%, and 40%. Left atrial V waves with peak height greater than 5 mm Hg above mean left atrial pressure frequently appear following mitral valve replacement, but these V waves are nonspecific signs of mitral regurgitation. 相似文献

A 74-year-old man had pustulant bilateral arthritis complicated with sepsis and disseminated intravascular coagulation (DIC). Microbiologic study of blood sample showed Streptococcus and methicillin resistant Staphylococcus aureus (MRSA). He was complicated with postulant diskitis since then. Medical treatment for DIC and administration of antibiotics were performed. Preoperative echocardiography revealed massive aortic regurgitation and vegetation of aortic valve, moderate pulmonary regurgitation and vegetation of pulmonary valve, massive mitral regurgitation, massive tricuspid regurgitation. He was diagnosed as infective quadruple valve endocarditis. He received aortic valve replacement, pulmonary valve replacement, mitral valve repair and tricuspid valve repair. Postoperative echocardiography showed satisfactory function of bioprosthesis. Postoperative course was uneventful. 相似文献

PGE1 has a beneficial effect on cardiac failure with mitral valve regurgitation by decreasing the "after load". An 82-year-old female had a total cystectomy of a bladder tumor. The preoperative standard 12 lead electrocardiogram showed atrial fibrillation and incomplete right bundle branch block. The preoperative echocardiogram showed regurgitation of both mitral valve and tricuspid valve. Under heavy premedication, we intubated with fentanyl and pancuronium bromide, maintained anesthesia with enflurane. After incision, both pulmonary artery pressure and pulmonary capillary wedge pressure increased, and cardiac index decreased. Continuous injection of 100ng.kg-1.min-1 PGE1 made pulmonary artery pressure and pulmonary capillary wedge pressure to decrease, and cardiac index to increase. PaO2, however, decreased apparently. PGE1 was effective for cardiac failure with mitral valve regurgitation associated with pulmonary hypertension. But attention must be given to the decrease in PaO2. 相似文献

A 48-year-old female was admitted to our hospital for examination of an abnormal shadow in the right lung field. She had a systolic murmur (4/6) over the apex and the chest radiograph revealed cardiac enlargement with three round opacities in the right lung field. Cardiac catheterization showed marked mitral regurgitation and large pulmonary varices. Pulmonary varix caused by mitral regurgitation was diagnosed. The size of the pulmonary varix was reduced with improvement of pulmonary artery wedge pressure one month after mitral valve replacement. We conclude that pulmonary varices can decrease in size secondary to lowering of left atrial pressure within one month after operation. 相似文献

Swan-Ganz catheter-induced massive hemoptysis and later pulmonary artery false aneurysm occurred in a patient with prosthetic mitral regurgitation. This patient was successfully managed by double-lumen endotracheal intubation, control of pulmonary hypertension, reversal of anticoagulation, mitral valve re-replacement, and transcatheter embolization. The pertinent literature is reviewed. 相似文献

Valvular heart disease in a parturient presenting for Cesarean section is challenging. A 25 year old primigravida parturient with severe mitral stenosis, mild mitral regurgitation, mild aortic regurgitation, and mild pulmonary arterial hypertension required Cesarean delivery after developing pulmonary edema. Low-dose spinal with hyperbaric bupivacine 0.5% 1.8 mL plus 25 μg of fentanyl was used for anesthesia. Chest ultrasonography (US) and transthoracic echocardiography (TTE) were used for monitoring purposes. Spinal-induced preload reduction improved the pulmonary edema, as evidenced by chest US. Chest US and TTE helped in fluid management. 相似文献

BACKGROUND: Several studies reported excellent long-term results after mitral valve repair for regurgitation, however a number of patients still experience recurrent mitral valve regurgitation which requires reoperation. We have evaluated the long-term outcome of a consecutive series of patients who underwent mitral valve repair for regurgitation in an attempt to identify the risk factors associated with late failures. PATIENTS AND METHODS: One-hundred and sixty-four patients underwent mitral valve repair for ischemic and degenerative mitral valve regurgitation. Seventy-two patients underwent echocardiographic evaluation a median of 5.6 years after surgery. RESULTS: Ten-year survival freedom from any fatal cardiac event was 75.9% and survival freedom from redo mitral valve surgery was 93.8%. Multivariable analysis showed that residual mitral valve regurgitation grade>1 as assessed during the immediate postoperative period (at 10-year, 60.6% vs. 95.7%, p=0.001, RR 20.7, 95%C.I. 3.4-125.3) and chronic obstructive pulmonary disease/asthma (at 10-year 66.8% vs. 95.2%, p=0.013, RR 12.0, 95%C.I. 1.7-85.2) were predictors of redo mitral valve surgery. The same findings were observed also among patients with myxomatous degenerative disease. At echocardiographic follow-up, no significant improvement was detected in terms of left ventricular ejection fraction, whilst mitral valve regurgitation grade (median, 3 to 1), New York Heart Association class (median, 2 to 1) and left atrium diameter (median, 50 to 44 mm) decreased significantly. CONCLUSIONS: This study confirms the excellent clinical long-term results after mitral valve repair. An adequate repair technique is advocated in order to decrease the immediate postoperative rate of residual regurgitation>1 as this is a main determinant of late failures requiring redo mitral valve surgery. Further studies are required to better define the possible causative role of chronic obstructive pulmonary disease and any underlying connective tissue metabolic disorder in late failures after mitral valve repair. 相似文献

The long-term results of closed mitral valvotomy performed between 1978 and 1985 in 198 patients with noncalcific mitral stenosis were analyzed. Follow-up data were available on 185 patients (93%); 1 patient died in the postoperative period, and 12 foreign patients were lost to follow-up. At the 4-year and 8-year intervals, 91% and 80% of patients, respectively, were event free (not in need of further operative procedures). By multivariate analysis, the factor preoperative mild mitral regurgitation showed a tendency to influence the event-free period. By univariate analysis, postoperative mitral regurgitation significantly reduced the event-free period. Twenty-one patients subsequently underwent mitral valve replacement; 8 for mitral regurgitation, 10 for mitral stenosis, and 3 for mixed mitral regurgitation and stenosis. By multivariate analysis, the reason for reoperation significantly influenced the length of the event-free period. The patients with mitral regurgitation required mitral valve replacement sooner than those with mitral stenosis. Advanced age, sex, previous valvotomy, preoperative New York Heart Association Functional Class, low mitral valve leaflet excursion, and pulmonary hypertension had no influence on the long-term result. 相似文献

INTRODUCTION: In order to improve the prognosis, repair of severe mitral regurgitation should be undertaken at the same time as aortic valve replacement in patients with severe aortic valve stenosis. However, mitral regurgitation may be secondary to pressure overload or ventricular dysfunction and improve after surgery. AIM: To assess the incidence of non-severe functional mitral regurgitation before and after isolated aortic valve replacement and determine its influence on the postoperative course. METHODS: The clinical and surgical characteristics were compared in a cohort of 577 consecutive patients who underwent isolated aortic valve replacement. RESULTS: The mean age was 68.4+/-9.2 years (44% women). Non-severe functional mitral valve regurgitation was detected prior to surgery in 26.5% of the patients. These patients were older (p=0.009), more often had ventricular dysfunction (p=0.005) and pulmonary hypertension (0.002), and had been admitted more frequently for heart failure (0.002), with fewer of them conserving sinus rhythm (p<0.001). Additionally, the pre-surgery existence of mitral regurgitation was associated with greater morbidity and mortality (10.5% vs 5.6%; p=0.025). The mitral regurgitation disappeared or improved prior to hospital discharge in 56.2% and 15.6%, respectively. Independent factors predicting this improvement were the presence of coronary lesions (OR 3.7, p=0.038), and the absence of diabetes (OR 0.28, p=0.011) and pulmonary hypertension (0.33, p=0.046). CONCLUSIONS: The presence of intermediate degree mitral regurgitation in patients undergoing isolated aortic valve replacement increases morbidity and mortality. However, a high percentage of those who do survive experience disappearance or improvement of the mitral regurgitation. 相似文献

Most reports of clinical experiences with palliation of acquired tricuspid regurgitation have failed to address the issue of coexisting disease of the mitral or aortic valve, or both. To accurately determine the natural history and the effect of operative interventions, we studied patients with chronic, pure mitral regurgitation who had surgical treatment at the National Heart, Lung, and Blood Institute from 1968 to 1984. Forty-seven patients fulfilled the criteria of a documented history of mitral regurgitation for more than 1.5 years, minimal mitral diastolic gradient, severe mitral regurgitation by angiography, and no prior mitral or tricuspid operative procedure. Twenty-five of the 47 patients (53%) had evidence of tricuspid regurgitation. No statistical differences in age, sex, mean duration of symptoms of congestive heart failure, or functional class were found between those patients with and those without tricuspid regurgitation. However, patients with symptoms of congestive heart failure for more than 6 years were more likely to have tricuspid regurgitation. This increased prevalence also correlated with higher elevations of left ventricular end-diastolic, systolic pulmonary artery, and mean right atrial pressures. The severity of tricuspid regurgitation estimated preoperatively did not correlate statistically with that determined by digital palpation, although the presence of tricuspid regurgitation was reliably confirmed. These data demonstrate that tricuspid regurgitation is frequently present in patients with chronic, pure mitral regurgitation and is associated with prolonged symptoms of congestive heart failure and significant alterations in right heart dynamics. 相似文献

The fate is described of 11 patients who had a stored pulmonary valve homograft mounted on a frame or in a Dacron jacket used for mitral valve replacement. Mitral regurgitation due to holes in the attenuated cusps occurred in nine by one year, requiring re-operation or causing death. Only one patient remains well with moderate mitral regurgitation after two years. 相似文献

A case of a successful surgical treatment for traumatic mitral valve regurgitation is reported. A 44-year-old, small-statured female with cretinism had a traffic accident. Eleven days after the accident, she was admitted to our hospital with severe respiratory distress syndrome by acute pulmonary edema. Echocardiography showed severe mitral regurgitation due to tendon rupture of posterior leaflet. Mitral valve plasty was performed successfully. 相似文献

Purpose: The aim of this study is to elucidate the impact of preoperative and postoperative pulmonary hypertension (PH) on long-term clinical outcomes after mitral valve repair for degenerative mitral regurgitation.Methods: A total of 654 patients who underwent mitral valve repair for degenerative mitral regurgitation between 1991 and 2010 were retrospectively reviewed. Patients were divided into PH(+) group (137 patients) and PH(–) group (517 patients). Follow-up was complete in 99.0%. The median follow-up duration was 7.5 years.Results: Patients in PH(+) group were older, more symptomatic and had higher tricuspid regurgitation grade. Thirty-day mortality was not different between 2 groups (p = 0.975). Long-term survival rate was lower in PH(+) group; 10-year survival rate after the operation was 85.2% ± 4.0% in PH(+) group and 89.7% ± 1.8% in PH(–) group (Log-rank, p = 0.019). The incidence of late cardiac events were not different between groups, however, the recurrence of PH was more frequent in PH(+) group. The recurrence of PH had an adverse impact on survival rate, late cardiac events and symptoms. Univariate analysis showed age and preoperative tricuspid regurgitation grade were the predictors of PH recurrence.Conclusion: Early surgical indication should be advocated for degenerative mitral regurgitation before the progression of pulmonary hypertension and tricuspid regurgitation. 相似文献
