Abstract：Objective To observe the clinical effect of Edwards MC3 tricuspid in valve annuloplasty for moderate and severe tricuspid regurgitation(TR). Methods Fifty-one patients with moderate and severe TR were divided into 3 groups. Twenty-one patients were given Edwards MC3 ring tricuspid valve annuloplasty; 12 Carpentier ring tricuspid valve annuloplasty and 18 De Vega tricuspid valve annuloplasty after LCVR were enrolled in this study. The TR grade of these patients were examined by 2D echocardiography preoperatively, 1 week, 3 months, 6 months,1 year and 3 years after surgery. Results There was no morbidity and mortality in three groups. The NYHA clincal function class was improved. The patients of MC3 tricuspid valve annuloplasty showed less residual tricuspid regurgitation than Carpentier ring and De Vega tricuspid valve annuloplasty 3 years after operation. The recurrence rate TR of MC3 ring tricuspid valve annuloplasty was significantly less than the Carpentier ring and De Vega tricuspid valve annuloplasty one year after surgery. Conclusion The early and middle term effect of MC3 ring tricuspid valve annuloplasty is better than that of Carpentier ring and De Vega tricuspid valve annulopla operation duration sty.
