Impact of concomitant tricuspid annuloplasty on right ventricular remodeling in patients with rheumatic mitral valve disease.


ABSTRACT:

Background

Studies on the management of functional tricuspid regurgitation (TR) during mitral valve operations have drawn inconsistent conclusions. This study was designed to compare the treatment strategy of concomitant tricuspid annuloplasty (TAP) against isolated mitral valve replacement (MVR) in rheumatic mitral valve disease patients, and to assess the effect of concomitant TAP on postoperative right ventricular (RV) remodeling and function.

Methods

One hundred-seventy patients with rheumatic mitral valve disease receiving MVR were categorized into TAP group (n?=?124) and non-TAP group (n?=?46). Clinical and echocardiographic data were collected preoperatively and at 1-year follow-up. Three-dimensional echocardiographic indices of RV geometry and function were analyzed.

Results

At baseline, concomitant TAP group had larger RV end-diastolic volume, more decreased RV ejection fraction and RV longitudinal strain than non-TAP group (all P?ConclusionsOur results suggest that concomitant TAP could improve RV remodeling and function for rheumatic mitral valve disease patients, while those with mild preoperative functional TR who had isolated MVR might experience RV dilation and deterioration of RV function at follow-up. Concomitant surgery for functional TR could be considered for patients undergoing MVR with rheumatic mitral valve disease.
