Abstract

Background:Whether there is a significant difference in the long-term surgical outcomes between suture annuloplasty and ring annuloplasty for the treatment of functional tricuspid regurgitation (TR) is still controversial. We compared the long-term outcomes of tricuspid annuloplasty (TAP) with and without an annuloplasty ring.

Methods and Results:From January 1996 to December 2015, we consecutively enrolled 684 patients (mean age, 65.5 years; 60% women) undergoing TAP for functional TR: 312 underwent conventional suture annuloplasty (Group S) and 372 underwent ring annuloplasty (Group R). Baseline characteristics were comparable between the 2 groups, except for age and the prevalence of prior cardiac surgery. The mean follow-up period was 7.3 years (range, 0.3–20.3 years).There was no significant difference in overall survival, freedom from major adverse cardiac and cerebrovascular events, and freedom from recurrent moderate to severe TR between Groups S and R, although postoperative mean TR grade and sPAP were significantly lower in Group R. Multivariate analysis revealed that age, prior cardiac surgery, and preoperative severe TR were independent predictors of recurrent moderate or greater TR.

Conclusions:There was no significant difference in the long-term surgical outcomes between ring and suture TAP, although postoperative mean TR grade was lower in the ring annuloplasty group.
