Impact of suture annuloplasty repair for moderate functional tricuspid regurgitation in rheumatic patients undergoing mitral valve replacement (Early outcome)

Abstract

Background: In this study, we examine the outcomes of tricuspid valve repair against non-repair to see if there is a near-term progression of non-corrected moderate functional TR in patients who had mitral valve replacement for rheumatic mitral disease and if RV size and function were affected. Objectives: To evaluate the effect of the De Vega annuloplasty for repair of moderate functional TV regurge during the left heart valve surgery in early post-operative period. Patients and methods:A prospective randomized controlled trial will contain (forty patients aged from 25 to 55 years of both sexes )they will be divided into two groups of patients: Group A: Twenty patients with moderate functional tricuspid regurgitation who received tricuspid valve annuloplasty (TVA) in the form of De vega repair along with mitral valve replacement. Group B: Twenty patients with moderate functional tricuspid regurgitation who received mitral valve replacement without tricuspid valve annuloplasty (TVA). Results: TR and right ventricle diameter were found to be significantly reduced in Group A. In group B, (6) individuals (30%) had developed grade IV/IV TR after 6 months, while 65% of patients developed competent tricuspid valve after 6 months in group A .Furthermore, in group B, TABSE (tricuspid annular systemic excursion) had dropped significantly to 1.7±0.2 cm. Conclusion: In the early postoperative period, tricuspid suture annuloplasty combined with MVR can prevent the advancement of tricuspid regurgitation, right ventricular dilatation, and systolic dysfunction.
