Right ventricular to pulmonary arterial coupling as a predictor of survival in patients undergoing mitral valve surgery for mitral regurgitation.

ABSTRACT:

Objectives

Right ventricular-to-pulmonary artery coupling has been associated with outcomes in mitral regurgitation treated by transcatheter approaches. We evaluated right ventricular-to-pulmonary artery coupling as a predictor of survival and postoperative length of hospital stay (LOS) in patients with mitral regurgitation undergoing mitral valve surgery.

Methods

In this retrospective analysis (median follow-up: 5.8 years), right ventricular-to-pulmonary artery coupling was quantified as the ratio of tricuspid annular plane systolic excursion to pulmonary artery systolic pressure (TAPSE/PASP) using transthoracic echocardiography. Receiver operating characteristic curve analysis was used to determine the optimum cut-point of TAPSE/PASP to predict all-cause mortality, and the
