Restrictive Mitral Valve Annuloplasty: Prognostic Implications of Left Ventricular Forward Flow

Kamperidis and colleagues report that left ventricular (LV) functional recovery after mitral valve (MV) repair for severe secondary mitral regurgitation is associated with improved patient outcomes. Their retrospective analysis of 130 patient records found increased LV forward ejection fraction and LV forward stroke volume after MV annuloplasty, despite no observed change in LV ejection fraction. The authors found that LV forward stroke volume after repair independently associated with overall survival and survival without major adverse cardiac-related events by multivariable analysis.
