Prognostic Implications of Cardiac Magnetic Resonance Imaging Characteristics in Primary Mitral Regurgitation.

ABSTRACT:

Background

Knowledge remains limited regarding the relationship between cardiac magnetic resonance (CMR) preoperative characteristics and postoperative clinical outcomes in primary mitral regurgitation (MR).

Objectives

The authors assessed the prognostic value of CMR preoperative characteristics in patients with primary MR due to prolapse or flail undergoing mitral valve surgery.

Methods

We retrospectively studied 284 patients (median age 61 years, 24% women) with chronic significant primary MR, who underwent CMR and echocardiography (echo) prior to mitral valve repair surgery. The endpoint was a composite of all-cause mortality, hospitalization for heart failure, stroke, or life-threatening ventricular arrhythmia.

Results

Over a median follow-up of 7.3 years (
