PurposeWe investigated the long-term outcomes of suture/ring tricuspid valve annuloplasty for functional tricuspid regurgitation associated with degenerative mitral regurgitation.MethodsWe retrospectively reviewed patients who underwent flexible ring tricuspid valve annuloplasty (n = 120) or suture tricuspid valve annuloplasty (n = 42) for functional tricuspid regurgitation concomitant with surgery for degenerative mitral regurgitation (mean follow-up duration, 5.3 ± 5.1 years).ResultsThe mean age of patients was 62.5 ± 13.1 years. Thirty-day mortality was zero in the suture group, and 0.8% in the ring group. Tricuspid regurgitation grade at discharge was lower in the ring group ( p = 0.002). No difference was observed between survival and freedom from major cardiac/cerebrovascular adverse events between the groups. However, freedom from ≥moderate tricuspid regurgitation was higher in the ring group (Log-rank p = 0.003). From univariate analysis, the risk factors for ≥moderate TR were suture annuloplasty and preoperative tricuspid regurgitation grade. No reoperation for recurrent tricuspid regurgitation occurred in either group because symptoms experienced by patients with recurrent tricuspid regurgitation were relatively insignificant.ConclusionConcomitant tricuspid annuloplasty using flexible bands offered improved durability than suture annuloplasty for preventing postoperative tricuspid regurgitation progression.
