Does stringent restrictive annuloplasty for functional mitral regurgitation cause functional mitral stenosis and pulmonary hypertension?
BACKGROUND It remains controversial whether restrictive mitral annuloplasty (RMA) for functional mitral regurgitation (MR) can induce functional mitral stenosis (MS) that may cause postoperative residual pulmonary hypertension (PH). METHODS AND RESULTS One hundred eight patients with left ventricular (LV) dysfunction and severe MR underwent RMA with stringent downsizing of the mitral annulus....
متن کاملMitral valve area during exercise after restrictive mitral valve annuloplasty: importance of diastolic anterior leaflet tethering.
BACKGROUND Restrictive mitral valve annuloplasty (RMA) for secondary mitral regurgitation might cause functional mitral stenosis, yet its clinical impact and underlying pathophysiological mechanisms remain debated. OBJECTIVES The purpose of our study was to assess the hemodynamic and clinical impact of effective orifice area (EOA) after RMA and its relationship with diastolic anterior leaflet...
متن کاملPreoperative posterior leaflet angle accurately predicts outcome after restrictive mitral valve annuloplasty for ischemic mitral regurgitation.
BACKGROUND Ischemic mitral regurgitation (MR) often persists after restrictive mitral valve annuloplasty, in which case it is associated with worse clinical outcomes. The goal of the present study was to determine whether persistence of MR and/or clinical outcome could be predicted from preoperative analysis of mitral valve configuration. METHODS AND RESULTS In 51 consecutive patients undergo...
متن کاملRestrictive annuloplasty for ischemic mitral regurgitation may induce functional mitral stenosis.
OBJECTIVES The purpose of this study was to evaluate mitral valve hemodynamic performance and functional capacity in patients with ischemic mitral regurgitation (MR) who underwent restrictive mitral valve annuloplasty (MVA). BACKGROUND Restrictive MVA combined with coronary artery bypass graft is the conventional approach for the surgical management of patients with ischemic MR. We hypothesiz...
متن کاملMechanism of beneficial effects of restrictive mitral annuloplasty in patients with dilated cardiomyopathy and functional mitral regurgitation.
BACKGROUND Restrictive mitral annuloplasty (RMA) often leads to reverse left ventricular (LV) remodeling in patients with advanced cardiomyopathy and functional mitral regurgitation. However, the mechanism responsible for its favorable effects on LV ejection performance has been poorly understood. We evaluated systolic wall stress using cineangiographic multidetector computed tomography (MDCT) ...
