Mitral valve surgery in advanced heart failure.
The appropriateness and timing of mitral valve surgery in patients with advanced heart failure and severe mitral regurgitation remains controversial. Recent surgical results provide evidence for beneficial effects on left ventricular remodeling and functional capacity. Given the absence of randomized trials comparing the outcomes of mitral valve surgery to medical therapy, however, clinical dec...
متن کاملMitral valve repair in heart failure.
Mitral regurgitation (MR) is a frequent complication of end-stage heart failure. Historically, these patients were either managed medically or with mitral valve replacement, both associated with poor outcomes. Mitral valve repair via an 'undersized' annuloplasty repair is safe and effectively corrects MR in heart-failure patients. All of the observed changes contribute to reverse remodeling and...
متن کاملMitral valve abnormalities in congestive heart failure
itral regurgitation (MR) of at least mild severity is present n up to 90% of patients with advanced congestive heart ailure (CHF) due to systolic dysfunction (1). It had long een assumed that MR results primarily from left ventriclar (LV) and mitral annular enlargement due to pathologic emodeling, with contributions as well from regional wall otion abnormalities and papillary muscle dysfunction...
متن کاملRole of mitral valve surgery for secondary mitral regurgitation in heart failure.
n nonischemic and ischemic cardiomyopathies, geometric perturations in the left ventricle (LV) result in dysfunction of the mitral alve and secondary (functional) mitral regurgitation (MR). An ncrease in interpapillary muscle distance, annular dilation, and nhanced leaflet tethering contribute to secondary MR. Because he MR in these patients is primarily a function of distorted LV eometry rathe...
متن کاملRight sided heart evaluation after successful mitral valve replacement.
Introduction: It is well-documented that right-sided heart dysfunction and significant tricuspid valve regurgitation (TVR) have adverse effects on patient outcomes after left-sided heart valve surgery. Therefore, the evaluation of right ventriclular (RV) function and TR severity in patients who had undergone mitral valve replacement (MVR), associated with/without concomitant su...
