Degenerative mitral valve regurgitation: surgical echocardiography.
Echocardiography is an essential tool in managing patients with mitral regurgitation. It allows identification and precise summation of anatomic lesions that lead to valve dysfunction. In this article, we highlight important aspects of mitral valve anatomy and pathophysiology as they pertain to surgical repair and discuss the critical role of echocardiography in surgical planning and assessment...
متن کاملExercise-induced changes in degenerative mitral regurgitation.
OBJECTIVES We sought to quantify exercise-induced changes in patients with degenerative mitral regurgitation (MR), to examine the relationship between exercise-induced changes in MR and in systolic pulmonary artery pressure (PAP), and to identify their potential impact on symptom-free survival. BACKGROUND MR severity can change during exercise in patients with functional MR. Quantified change...
متن کاملImaging Exercise Pulmonary Hypertension in Asymptomatic Degenerative Mitral Regurgitation
Background—Current guidelines recommend mitral valve surgery for asymptomatic patients with severe degenerative mitral regurgitation and preserved left ventricular systolic function when exercise pulmonary hypertension (PHT) is present. However, the determinants of exercise PHT have not been evaluated. The aim of this study was to identify the echocardiographic predictors of exercise PHT and th...

متن کاملPrediction of exercise pulmonary hypertension in asymptomatic degenerative mitral regurgitation.
OBJECTIVE Exercise systolic pulmonary arterial pressure (SPAP) predicts the occurrence of symptoms in patients with degenerative mitral regurgitation (MR). However, this measurement is not always available. The purpose of this study was to identify resting echocardiographic predictors of exercise SPAP and whether predicted exercise SPAP may predict symptom-free survival. METHODS We prospectiv...
