Is right ventricular systolic function reduced after cardiac surgery? A two- and three-dimensional echocardiographic study

A reduction in tricuspid annular plane systolic excursion (TAPSE) and peak systolic velocity (PSV) of tricuspid annulus after cardiac surgery is a well-known phenomenon, even though its origin is not well established. Recently, a new three-dimensional (3D) echocardiographic software adapted for right ventricular (RV) analysis has been validated. Aims of this study were to evaluate RV function in patients with mitral valve prolapse undergoing surgical valvular repair and to compare and correlate 3D RV ejection fraction (RVEF) with TAPSE and PSV before and after surgery.
