Abstract：Objective To comparatively analyze the clinical outcome of modified individually Edwards MC3 tricuspid valve annuloplasty for treating the patients with secondary moderate-severe tricuspid regurgitation. Methods We performed tricuspid valve annuloplasty with Edwards MC3 ring in 72 patients who suffered from moderate to severe secondary tricuspid valve regurgitation from 2005 to 2007 in our hospital. The patients were divided into two groups. 36 patients received Edwards MC3 tricuspid valve annuloplasty by classical method (classical method group) and 36 patients by modified method (modified method group). Results Fifty nine patients received the follow-up study at endtime of 5 years. There were no significant differences in two groups of patients about fundamental condition and left-sided valve operation (P > 0.05). The follow-up patients of modified method group had smaller tricuspid valve diameter than the patients of classical method group [(26.1 ± 1.8) mm vs (27.5 ± 2.2)mm, P < 0.05]. And the moderate-severe tricuspid regurgitation in modified method group was less than that in classical method group (6.5% vs 28.6%, P < 0.05). Conclusion The individually modified tricuspid valve annuloplasty with Edwards MC3 annuloplasty ring is effective for treating the secondary moderate-severe tricuspid regurgitation, but need longer-term follow-up study.
