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

A 50-year-old woman was admitted to our hospital because of heart failure (NYHA III) due to mitral valve regurgitation (MR) with pulmonary hypertension (PH) and tricuspid valve regurgitation (TR). She had a history of chronic renal failure undergoing dialysis (peritoneal dialysis, homodialysis) since 1996. Cardiac catheterization and ultrasonic cardiography showed severe MR (Sellers III), severe TR and PH (mean pressure 33 mmHg). So we performed mitral valve replacement and tricuspid annuloplasty (DeVega). Frequent blood transfusion was needed because severe hemolytic anemia appeared after operation. Ultrasonic cardiography demonstrated moderate aortic valve regurgitation (AR) with no paravalvular prosthetic leakage. We diagnosed hemolytic anemia due to AR. We performed aortic valve replacement. Hemolytic anemia improved soon after second operation. We investigated the mechanical process of the AR. She had a very short subaortic curtain (5.9 mm) compared with the average (8.7 +/- 2.1 mm: mean +/- SD) of cardiac patients. We think that we must be very careful with suture to short subaortic curtain. In addition measurement of subaortic curtain before operation is very useful. 相似文献

Aortic valve pathology is the most common acquired valvular heart disease in the adults of western countries, and mitral regurgitation (MR) is often clinically present in patients with degenerative aortic stenosis or insufficiency. Many studies report an incidence of MR between 65-75% in patients evaluated for aortic valve replacement. Severe aortic valve disease may be associated with functional mitral regurgitation (FMR) defined as the failure of mitral valve to prevent systolic backward flow in the absence of any significant structural or intrinsic valvular disease. Increased afterload and left ventricular remodeling have been implicated to explain FMR in patients with aortic valve disease. Moreover, organic mitral valve disease can be associated with aortic stenosis and can be rheumatic or degenerative. We have examined the data of the literature to understand the evolution of MR, the impact of mitral regurgitation on the outcome of patients undergoing aortic valve replacement, and to determine clinical predictors of prognosis in patients with concomitant MR at the time of aortic valve replacement. 相似文献

We report a case of severe aortic regurgitation occurring immediately after the insertion of a mitral annuloplasty ring. On transesophageal echocardiography, regurgitation was found to originate from the retracted left coronary cusp. On direct examination, part of the aortic wall was folded, but no suture could be identified. It was reasoned that tension created by the ring caused the retraction. The problem was corrected by releasing three sutures on the ring. Postoperative course was uneventful. 相似文献

No data are available in the literature regarding the effectiveness and safety of transcatheter aortic valve implantation in patients who underwent previous mitral valve ring repair. Concerns exist related to the possible interference between the percutaneous aortic valve and the mitral annuloplasty ring. We report our experience with percutaneous aortic self-expandable valve implantation in a 76-year-old woman affected by severe aortic stenosis, previously operated on for "undersized" mitral annuloplasty repair of severe functional mitral regurgitation in dilated cardiomyopathy. No deformation of the nitinol tubing of the CoreValve device (CoreValve, Inc, Irvine, CA), neither distortion nor malfunction nor change of the conformation of the mitral ring occurred. No change in mitral function and regurgitation was evident at echocardiography monitoring, which was performed during the implant. 相似文献
