Retrospective Study to Compare Ring Annuloplasty and Suture Annuloplasty in Tricuspid Valve Diseases

Abstract

The Tricuspid regurgitation may be primary or secondary to left sided heart disease Residual tricuspid regurgitation is seen after tricuspid valve annuloplasty(TVA) - both ring and suture anuloplasty. A study was conducted in KEM Hospital as to validate the benefits of ring annuloplasty over suture anoloplasty. 80 patients undergoing MVR and TVA were studied. Of these 50 patients underwent MVR with ring annuloplasty and 30 underwent MVR with DeVegas annuloplasty. 2DECHO was done pre and postoperatively to determine pulmonary artery systolic pressure(PASP), grade of tricuspid regurgitation (TR), LV ejection fraction(LVEF) and tricuspid annulus. 82% of patients of ring annuloplasty group had reduction in PASP postoperatively compared to 56% in DeVegas annuloplasty . Grade of TR improved from moderately severe TR to mild TR in 86% in the ring annuloplasty group compared to53% in DeVegas annuloplasty group. 58% of patients of ring annuloplasty had maintained LV function postoperatively compared to 46% of patients in DeVegas annuloplasty.The mean tricuspid annulus showed reduction from preoperative annulus size of 37.72 to 27.5 in ring annuloplasty group and from 37.9to 27.13 in DeVegas annuloplasty group. Tricuspid ring annuloplasty is a better and durable repaire compared to suture annuloplasty for secondary TR. Aggressive management of secondary TR such as this could hopefully decreas the occurence of late TR following previous left sided valve surgery
