目的：总结改良De Vega环缩术治疗功能性三尖瓣返流的疗效。方法功能性三尖瓣返流患者63例随机分为两组，分别接受改良De Vega环缩术（A组，33例）和经典De Vega环缩术（B组，30例），比较两组疗效。结果术前两组患者病情相仿（ P＞0．05）。术后A、B两组患者三尖瓣返流程度均减轻、心功能分级和左室射血分数（LVEF）均有改善（P＜0．05）。远期随访，A组三尖瓣返流程度轻于B组（P＜0．05）。结论改良De Vega环缩术治疗功能性三尖瓣返流临床疗效确切，减轻三尖瓣返流效果优于经典De Vega环缩术。“,”Objective To summarize the efficacy of modified De Vega annuloplasty in the treatment of functional tricuspid regurgitation(FTR) .Methods A total of 63 patients with FTR was randomly divided into two groups of A(operated with modified De Vega annuloplasty ,33 cases) and B (operated with conventional De Vega annuloplasty ,30 cases) .The efficacy was compared between two groups .Results There were no statistically differences in tricuspid regurgitation and cardiac function between two groups before operation ( P>0 .05 ) .Compared with before ,postoperative tricuspid regurgitation was alleviated ,the classification of cardiac function and left ventricular ejection fraction (LVEF) were improved in both groups after operation(P<0 .05) .Long‐term follow‐up showed that tricuspid regurgitation was less in group A than that in group B(P<0 .05) .Conclusion The modified De Vega annuloplasty is effective and the efficacy of reducing tricuspid regurgitation is superior to the conventional De Vega annuloplasty .
