    ObjectiveThis study was conducted to compare the outcomes of rigid ring versus De Vega annuloplasty for the treatment of functional tricuspid regurgitation (TR).MethodsFrom 2003 to 2017, De Vega annuloplasty (group D) was used in 231 patients, and rigid ring annuloplasty (group R) was used in 204 patients for the treatment of functional TR during left-sided valve surgery. A propensity score-matching analysis was used to pair group D (n = 109) with group R (n = 109). The primary outcomes were long-term overall survival and cardiac death, and the secondary outcomes were tricuspid valve-related events and TR recurrence (TR moderate or severe). The follow-up data were complete in 99.6% (447 out of 449) of the patients with a follow-up duration of 102 months.ResultsThere were no differences in the overall survival and cardiac death between the propensity score-matched groups (P = .793 and P = .175, respectively) up to 14 years after surgery. Tricuspid valve-related events, including cardiac death, permanent pacemaker implantation, thromboembolism, bleeding and tricuspid valve reoperation were also similar between the 2 matched groups during the follow-up (P > .999). However, cumulative incidence of TR recurrence was significantly higher in group R than in group D (P = .007). Multivariate analysis indicated the annuloplasty method (De Vega) and preoperative TR grade as risk factors for late TR recurrence.ConclusionsIn functional TR, annuloplasty methods did not influence long-term overall survival, cardiac mortality, and tricuspid valve-related events. However, rigid ring annuloplasty showed less late TR recurrence. Rigid ring annuloplasty can be considered for the treatment of functional TR in terms of its better durability.Copyright © 2020.
