Objective
The appearance of atrial fibrillation is associated with significant clinical deterioration in patients with obstructive hypertrophic cardiomyopathy; therefore, maintenance of sinus rhythm is desirable. Guidelines and most articles have reported the results of catheter ablation and pharmacologic atrial fibrillation treatment; nevertheless, data regarding concomitant procedures during septal myectomy are limited. The aim of this study was to assess the outcomes of concomitant atrial fibrillation treatment in patients with obstructive hypertrophic cardiomyopathy.Methods
Between 2010 and 2013 in our clinic, 187 patients with obstructive hypertrophic cardiomyopathy underwent extended myectomy. In 45 cases, concomitant Cox-Maze IV procedure was performed; however, obstructive hypertrophic cardiomyopathy was the primary indication for surgery. Atrial fibrillation was paroxysmal in 26 patients (58%) and nonparoxysmal in 19 patients (42%). The mean age of patients was 52.8 ± 14.2 years (range, 22-74 years). Mean peak gradient was 90.7 ± 24.2 mm Hg, and interventricular septum thickness was 26.1 ± 4.3 mm. Mean atrial fibrillation duration was 17.3 ± 8.5 months.Results
There were no early deaths. No procedure-related complications occurred with regard to ablation procedure. Complete atrioventricular block was achieved in 2 patients (4.0%). Mean crossclamping time was 61 ± 36 minutes. Peak left ventricular outflow tract gradient was 12.6 ± 5.5 mm Hg based on transesophageal echocardiography. The Maze IV procedure was used for ablation in all patients (radiofrequency ablation with bipolar clamp + cryolesion for mitral and tricuspid lines). Because of the atrial wall thickness (5-6 mm), applications were performed 8 to 10 times on each line. There were no cases of pacemaker implantation due to sinus node dysfunction. All patients were discharged in stable sinus rhythm. Mean follow-up was 23.7 ± 1.3 months. The rate of atrial fibrillation freedom was 100% (45 patients) at 6 months, 89% (40 patients) at 1 year, and 78% (35 patients) at 24 months.Conclusions
Concomitant ablation atrial fibrillation during septal myectomy in patients with obstructive hypertrophic cardiomyopathy is a safe and effective procedure and should be considered carefully in this patient group. 相似文献5.

Cor triatriatum is a rare congenital heart disease. A 57‐year‐old woman had cor triatriatum with severe mitral valve regurgitation (MR) and atrial fibrillation (AF). We performed mitral valve repair, left atrial appendage resection, and maze procedure by resection of the anomalous septum in the left atrium. As a result, MR was controllable and AF disappeared after the operation. Although there is no established maze procedure with cor triatriatum, removing the septum was effective to complete it. 相似文献

Objective
Newly published guidelines made the highest level recommendation for surgical treatment for atrial fibrillation. However, the number of patients without a mitral valve procedure with atrial fibrillation who are treated with concomitant surgical ablation is still low (15%-25%), because surgeons are reluctant to perform procedures in patients who would not otherwise require left atriotomy. The purpose of this study was to compare the outcomes of concomitant Cox maze with and without mitral valve procedures.Methods
Patients who underwent concomitant Cox maze procedures were prospectively followed since September 2005. Of the 711 patients, 238 did not receive mitral valve surgery. Propensity score matching was conducted to balance preoperative characteristics between patients with and without mitral valve procedures (164/group after matching).Results
Before matching, patients in the mitral valve group were younger (65 vs 67 years, P = .047) and had higher euroSCORE II (European System for Cardiac Operative Risk Evaluation; 3.2% vs 2.6%, P = .002), larger mean left atrial size (5.3 vs 4.8 cm, P < .001), and shorter median atrial fibrillation duration (19 vs 25 months, P = .064). Early outcomes were similar for the matched groups. Cumulative 5-year freedom from stroke did not differ between matched mitral valve and non–mitral valve groups (96.1% vs 96.6%, P = .667). At each time point, the proportion in sinus rhythm off antiarrhythmic medications was similar for the matched groups, including 5 years after surgery (68% vs 63%, P = .492).Conclusions
The Cox maze procedure is safe and effective with comparable outcomes when performed concomitant to mitral valve or non–mitral valve surgery. Surgeons should base the decision to perform surgical ablation procedures on atrial fibrillation pathophysiology and the benefit to patients, not on the type of concomitant procedure. 相似文献10.

Objectives
An increasing number of octogenarians are referred to undergo mitral valve surgery for degenerative disease, and percutaneous approaches are being increasingly used in this subgroup of patients. We sought to determine the survival and its predictors after Mitral Valve Surgery in Octogenarians (MiSO) in a multicenter UK study of high-volume specialized centers.Methods
Pooled data from 3 centers were collected retrospectively. To identify the predictors of short-term composite outcome of 30 days mortality, acute kidney injury, and cerebrovascular accident, a multivariable logistic regression model was developed. Multiple Cox regression analysis was performed for late mortality. Kaplan–Meier curves were generated for long-term survival in various subsets of patients. Receiver operating characteristic analysis was done to determine the predictive power of the logistic European System for Cardiac Operative Risk Evaluation.Results
A total of 247 patients were included in the study. The median follow-up was 2.9 years (minimum 0, maximum 14 years). A total of 150 patients (60.7%) underwent mitral valve repair, and 97 patients (39.3%) underwent mitral valve replacement. Apart from redo cardiac surgery (mitral valve repair 6 [4%] vs mitral valve replacement 11 [11.3%], P = .04) and preoperative atrial fibrillation (mitral valve repair 79 [52.6%] vs mitral valve replacement 34 [35.1%], P < .01), there was no significant difference in terms of any other preoperative characteristics between the 2 groups. Patient operative risk, as estimated by logistic European System for Cardiac Operative Risk Evaluation, was lower in the mitral valve repair group (10.2 ± 11.8 vs 13.7 ± 15.2 in mitral valve replacement; P = .07). No difference was found between groups for duration of cardiopulmonary bypass and aortic crossclamp times. The 30-day mortality for the whole cohort was 13.8% (mitral valve repair 4.7% vs mitral valve replacement 18.6%; P < .01). No differences were found in terms of postoperative cerebrovascular accident (2% vs 3.1%; P = .9), acute kidney injury requiring dialysis (6.7% vs 13.4%; P = .12), and superficial or deep sternal wound infection (10% vs 16.5%, P = .17; 2% vs 3.1%, P = .67, respectively). The final multiple regression model for short-term composite outcome included previous cardiac surgery (odds ratio [OR], 4.47; 95% confidence interval [CI], 1.37-17.46; P = .02), intra-aortic balloon pump use (OR, 4.77; 95% CI, 1.67-15.79; P < .01), and mitral valve replacement (OR, 7.7; 95% CI, 4.04-14.9; P < .01). Overall survival for the entire cohort at 1, 5, and 10 years was 82.4%, 63.7%, and 45.5% (mitral valve repair vs mitral valve replacement: 89.9% vs 70.7% at 1 year, 69.6% vs 54% at 5 years, and 51.8% vs 35.5% at 10 years; P = .0005). Cox proportional hazard model results showed mitral valve replacement (hazard ratio, 1.88; 95% CI, 1.22-2.89; P < .01) and intra-aortic balloon pump use (hazard ratio, 2.54; 95% CI, 1.26-5.13; P < .01) to be independent predictor factors affecting long-term survival. Logistic European System for Cardiac Operative Risk Evaluation did not perform well in predicting early mortality (area under the curve, 0.57%).Conclusions
In octogenarians, mitral valve repair for degenerative disease is associated with good survival and remains the gold standard, whereas mitral valve replacement is still associated with significant mortality. Logistic European System for Cardiac Operative Risk Evaluation was unable to predict early mortality in our cohort of patients. Larger international multicenter registries are required to optimize the decision-making process in such a high-risk subgroup. 相似文献14.

Objective
Atrial fibrillation (AF) is associated with an increased mortality risk. The Cox-maze IV procedure (CM4) performed concomitantly with other cardiac procedures has been shown to be effective for restoring sinus rhythm. However, few data have been published on the late survival of patients undergoing a concomitant CM4.Methods
Patients undergoing cardiac surgery were retrospectively reviewed from 2001 to 2016 (n = 10,859). Patients were stratified into 3 groups: patients with a history of AF receiving a concomitant CM4 (CM4; n = 438), patients with a history of AF unaddressed during surgery (Untreated AF; n = 1510), and patients without AF history (No AF; n = 8911). Propensity score matching was conducted between the CM4 and Untreated AF groups, and between the CM4 and No AF groups.Results
Thirty-day mortality was similar between the matched groups. Kaplan-Meier analysis showed greater survival for CM4 compared to Untreated AF (P = .004). Ten-year survival was 62% for CM4 and 42% for Untreated AF. Adjusted hazard ratio was 0.47 (95% confidence interval, 0.26-0.86, P = .014). No difference in survival was found between CM4 and No AF groups with the Kaplan–Meier analysis (P = .847). Ten-year survival was 63% for CM4 and 55% for No AF. Adjusted hazard ratio was 1.03 (95% confidence interval, 0.51-2.11, P = .929).Conclusions
For selected patients with a history of AF undergoing cardiac surgery, concomitant CM4 did not add significantly to postoperative morbidity or mortality and was associated with improved late survival compared with patients with untreated AF and a similar survival to patients without a history of AF. 相似文献15.

Given the paucity of available literature, we sought to evaluate the mechanisms of tricuspid regurgitation and the outcomes of tricuspid valve surgery in the presence of permanent pacemakers.Methods
We retrospectively reviewed the records of 622 adult patients who underwent tricuspid valve surgery in the presence of permanent pacemakers between January 1993 and December 2013. Those with prosthetic tricuspid valve or tricuspid valve endocarditis and those undergoing concomitant heart transplant were excluded (n = 23). Patients were divided into 2 etiologic groups: pacemaker-associated tricuspid regurgitation (n = 349, 58%) and pacemaker-induced tricuspid regurgitation (n = 249, 42%). One patient was not categorized, because permanent pacemaker involvement was unknown.Results
Mean age was 69.5 ± 12.0 years; 312 patients (52%) were female. In pacemaker-associated tricuspid regurgitation, the most common cause was functional (n = 304, 87%). The most common mechanism leading to pacemaker-induced tricuspid regurgitation was restricted leaflet mobility (n = 101, 41%), followed by adherent leaflet to the leads (n = 93, 37%), leaflet perforation (n = 30, 12%), scarring of leaflets (n = 19, 8%), and chordal entrapment (n = 18, 7%). The most common leaflet involved was septal leaflet (n = 182, 73%). Tricuspid valve repair (n = 215, 62%) was higher in the pacemaker-associated tricuspid regurgitation group. In multivariable analysis, pacemaker-induced tricuspid regurgitation was found to be protective with improved survival (hazard ratio [HR], 0.79; 95% confidence interval [CI], 0.68-0.98). Other independent risk factors of mortality included tricuspid valve replacement (HR, 1.50; 95% CI, 1.20-1.87), nonelective surgery (HR, 1.66; 95% CI, 1.33-2.08), diabetes (HR, 1.37; 95% CI, 1.09-1.73), severe tricuspid regurgitation (HR, 1.42; 95% CI, 1.04-1.95), and older age when there was a concomitant aortic valve surgery (HR, 1.44; 95% CI, 1.15-1.79).Conclusions
Several mechanisms lead to pacemaker-induced tricuspid regurgitation. Pacemaker-induced tricuspid regurgitation when compared with pacemaker-associated tricuspid regurgitation carries a better prognosis with improved survival. 相似文献16.

Objective
The study objective was to evaluate the impact of various surgical characteristics and practices on the risk of postoperative atrial fibrillation and other adverse outcomes after cardiac surgery.Methods
By using the prospectively collected data of patients who underwent cardiac surgery in 28 centers across the United States, Italy, and Argentina, the details of surgery characteristics were collected for each patient and the outcomes, including postoperative atrial fibrillation, major adverse cardiovascular events, and mortality. These were evaluated via multivariable-adjusted models.Results
In 1462 patients, a total of 460 cases of postoperative atrial fibrillation, 33 major adverse cardiovascular events, 23 cases of 30-day mortality, and 46 cases of 1-year mortality occurred. We found that type of surgery and cardiopulmonary bypass use predicted the occurrence of postoperative atrial fibrillation. Compared with coronary artery bypass grafting alone, there was a higher risk of postoperative atrial fibrillation with valvular surgery alone (odds ratio, 1.4; 95% confidence interval, 1.1-1.9), and the risk was even higher with concomitant valvular and coronary artery bypass grafting surgery (odds ratio, 1.8; 95% confidence interval, 1.2-2.7). Compared with no bypass, use of cardiopulmonary bypass was associated with higher risk of postoperative atrial fibrillation (odds ratio, 2.4; 95% confidence interval, 1.7-3.5), but there were significant age and sex differences of the impact of bypass use among patients undergoing coronary artery bypass grafting (P for interaction = .04). In addition, compared with spontaneous return of rhythm, ventricular pacing was associated with a higher risk of major adverse cardiovascular events (odds ratio, 5.0; 95% confidence interval, 1.4-18), whereas concomitant coronary artery bypass grafting and valvular surgery was associated with a higher risk of 30-day mortality (hazard ratio, 4.3; 95% confidence interval, 1.2-14) compared with coronary artery bypass grafting alone. Occurrence of postoperative atrial fibrillation was associated with greater length of stay and 1-year mortality (hazard ratio, 2.2; 95% confidence interval, 1.2-3.9).Conclusions
In this multicenter trial, we identified specific adverse outcomes that are associated with concomitant valvular and coronary artery bypass graft surgery, cardiopulmonary bypass, ventricular pacing, and occurrence of postoperative atrial fibrillation. 相似文献17.

Background
Paravalvular leak (PVL) is often seen after aortic (AV) and mitral valve (MV) surgery, either due to infection or valve dehiscence. We sought to describe predictors of longer-term outcomes in patients who developed PVL after AV and MV surgery and were considered eligible for reoperative cardiac surgery (RCS).Methods
We studied 495 such patients (65 ± 14 years, 65% men, 47% with MV PVL) who presented at our center between January 2003 and December 2011. Patients with severe mitral/aortic stenosis, patients with less than mild PVL, and those with prohibitive risk precluding RCS were excluded. Society of Thoracic Surgeons (STS) score was calculated. Primary endpoint was mortality.Results
At baseline, mean STS score and left ventricular ejection fraction were 5.8 ± 4% and 52 ± 12%, respectively. In total, 105 (21%) had infective PVL and 72% had moderate or greater PVL. At a median of 8 days, 351 (71%) patients underwent RCS to repair PVL (3% in-hospital postoperative mortality), and at 6.6 ± 4 years, 230 (47%) patients died. On multivariable Cox survival analysis, greater STS score (hazard ratio or HR 1.35), mitral versus aortic PVL (HR 1.66), infectious etiology (HR 2.05), and greater right ventricular systolic pressure (HR 1.09) were associated with greater longer-term mortality, whereas surgery (HR 0.58) was associated with improved longer-term survival (all P < .05).Conclusions
Patients who develop mild or greater PVL after AV/MV surgery have a high rate of longer-term mortality, despite excellent perioperative outcomes. Greater STS score, right ventricular systolic pressure, infectious etiology, and MV (vs AV) involvement were all independently associated with long-term mortality, whereas RCS for PVL closure was associated with improved longer-term survival. 相似文献18.

ObjectiveDeterioration of the native aortic valve function by a late progression of rheumatic disease is not infrequent in patients who underwent rheumatic mitral valve surgery; however, this phenomenon has not been clearly quantified.MethodsA total of 1155 consecutive patients (age 52.0 ± 12.9 years; 807 female) who underwent rheumatic mitral valve surgery without concomitant aortic valve surgery from 1997 to 2015 were enrolled. The primary end point was the composite of progression to severe aortic valve dysfunction or a requirement of subsequent aortic valve replacements during follow-up. To determine the risk factors of the primary outcome, we performed the generalized linear mixed model.ResultsThe baseline severities of aortic valve were none to trivial in 880 patients (76.2%), mild in 256 patients (22.2%), and moderate in 19 patients (1.6%). The latest 1062 echocardiographic assessments (91.9%; median, 81.2 postoperative months; interquartile range, 37.3-132.1 months) demonstrated 26 cases (0.33%/patient-year) meeting the primary end point during follow-up. Cumulative incidence of the primary end point at 10 years was 0.4% ± 0.3% and 7.4% ± 2.5% depending on the presence of mild or greater aortic valve dysfunction at baseline (P < .01). In multivariable analyses, aortic valve peak pressure gradient (odds ratio, 1.14; 95% confidence interval, 1.10-1.20), aortic regurgitation degree (mild over none: odds ratio, 3.26; 95% confidence interval, 1.15-9.23), and time (odds ratio, 1.30; 95% confidence interval 1.19-1.41) were significantly associated with the occurrence of the primary end point.ConclusionsProgression of severe aortic valve dysfunction and the need for aortic valve replacement are uncommon in patients undergoing rheumatic mitral valve surgery. However, such events were relatively common among those with mild or greater aortic valve dysfunction at the time of mitral valve surgery. 相似文献

Background
This study compares early and late outcomes in patients undergoing coronary artery bypass grafting with and without preoperative atrial fibrillation in a contemporary, nationally representative Medicare cohort.Methods
In the Medicare-Linked Society of Thoracic Surgeons database, 361,138 patients underwent isolated coronary artery bypass from 2006 to 2013, of whom 37,220 (10.3%) had preoperative atrial fibrillation; 13,161 (35.4%) were treated with surgical ablation and were excluded. Generalized estimating equations were used to compare 30-day mortality and morbidity. Long-term survival was summarized using Kaplan-Meier curves and Cox regression models. Stroke and systemic embolism incidence was modeled using the Fine-Gray model and the CHA2DS2-VASc score was used to analyze stroke risk. Median follow-up was 4 years.Results
Preoperative atrial fibrillation was associated with a higher adjusted in-hospital mortality (odds ratio [OR], 1.5; P < .0001) and combined major morbidity including stroke, renal failure, prolonged ventilation, reoperation, and deep sternal wound infection (OR, 1.32; P < .0001). Patients with preoperative atrial fibrillation experienced a higher adjusted long-term risk of all-cause mortality and cumulative risk of stroke and systemic embolism compared to those without atrial fibrillation. At 5 years, the survival probability in the preoperative atrial fibrillation versus no atrial fibrillation groups stratified by CHA2DS2-VASc scores was 74.8% versus 86.3% (score 1-3), 56.5% versus 73.2% (score 4-6), and 41.2% versus 57.2% (score 7-9; all P < .001).Conclusions
Preoperative atrial fibrillation is independently associated with worse early and late postoperative outcomes. CHA2DS2-VASc stratifies risk, even in those without preoperative atrial fibrillation. 相似文献20.
