- Abstract
- OBJECTIVES: Ring annuloplasty is now regarded as the standard surgical technique for the correction of tricuspid regurgitation (TR). However, comparative research on the durability of commercially available annuloplasty rings is limited. We reviewed early and late surgical results of tricuspid annuloplasty using the Duran AnCore and Edwards MC3 rings. METHODS: From our institutional prospective cardiac surgical database, we identified 581 adult patients (55.9 +/- 12.9 years) undergoing tricuspid ring annuloplasty using either a Duran AnCore (n = 370; Duran group) or an Edwards MC3 ring (n = 211; MC3 group) from January 2001 through December 2012. Survival rates, valve-related outcomes and late tricuspid functions were compared between the 2 groups. Propensity score analysis was conducted to adjust for selection bias. RESULTS: The degree of TR assigned preoperatively was mild in 128 (22.0%), moderate in 205 (35.3%), and severe in 248 patients (42.7%), with a higher prevalence of severe TR in the Duran group than in the MC3 group (46.5% vs 36.0%; P = 0.014). Over an observation period of 47.0 months, 46 patients developed significant TR (>= moderate). After propensity score matching, there were no significant differences in the risks of early mortality (P = 0.36), early complications (P > 0.99) and recurrence of significant TR (P = 0.33). CONCLUSIONS: Both the Duran and the MC3 rings showed comparable safety and tricuspid valve durability for tricuspid valve annuloplasty.
