CHINA CLINICAL PRACTICAL MEDICINE（2009）
Abstract
目的 借助于心脏超声评价C形软环和改良De Vega成形术治疗功能性三尖瓣返流的疗效.方法 选择因功能性三尖瓣返流行C形软环成形术患者32例和改良De Vega成形术患者31例,对术前、术后的下列指标进行随访观察比较:右心房横径,右心室内径,三尖瓣返流程度.结果 右心房内径、右心事内径和三尖瓣返流程度在术后近期均明显下降,2组间差异无显著性,但远期的以上各指标C形软环环成形组要优于改良De Vega成形组.结论 C形软环环成形术和改良De Vega成形术治疗功能性三尖辫返流的近期效果相似,远期效果C形软环环成形术优于改良De Vega成形术.
