Late development of mitral regurgitation after left ventricular reconstruction surgery.
PURPOSE Late presence of mitral regurgitation (MR) after the Dor procedure (left ventricular (LV) reconstruction associated with coronary artery bypass grafting) for postinfarction patients carries a poor prognosis. The aim of this study was to review our experience with the Dor procedure and to analyze the correlation of surgical results with late MR. METHODS The study group comprised 19 pat...
متن کاملLeft Ventricular Response to Mitral Regurgitation
Mitral regurgitation (MR) burdens the left ventricle with a volume load that leads to a series of left ventricular (LV) compensatory adaptations and adjustments that vary considerably during the prolonged clinical course of MR.1–4 The early compensatory changes observed in acute MR (ie, utilization of the Frank-Starling mechanism) are gradually replaced by a chronic remodeling process with enla...

متن کاملPredictors of left ventricular dysfunction following mitral valve repair for mitral regurgitation.
e read the study by Matsumura et al. (1) and the accompanying ditorial by Wisenbaugh (2) with great interest. Unfortunately, in eveloping countries, rheumatic heart disease remains the major ause for severe mitral regurgitation. Furthermore, many patients re seen for the first time when adverse echocardiographic charcteristics such as an ejection fraction 60% or an end-systolic iameter 45 mm ar...
متن کاملIs mitral valve repair superior to replacement for chronic ischemic mitral regurgitation with left ventricular dysfunction?
BACKGROUND This study was undertaken to compare mitral valve repair and replacement as treatments for ischemic mitral regurgitation (IMR) with left ventricular dysfunction (LVD). Specifically, we sought to determine whether the choice of mitral valve procedure affected survival, and discover which patients were predicted to benefit from mitral valve repair and which from replacement. METHODS ...
