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.
