摘要

对于成人，卡朋蒂埃分类 II 型二尖瓣反流的标准二尖瓣修复术是使用人工腱索重建二尖瓣。在儿童患者中，要在受限的二尖瓣下腔隙中的乳头肌和脱垂的二尖瓣叶之间放置长度精确的人工腱索在技术上有一定难度。我们采用改良的固定环入环技术成功地为 3 名儿童患者进行了二尖瓣修复手术。

Modified Fixed Loop-in-Loop Technique in Mitral Valve Repair for Children

For adults, the standard procedure for mitral valve repair of Carpentier classification type II mitral regurgitation is reconstruction with artificial chordae. In children, placement of artificial chordae of precise length between the papillary muscle and prolapsed mitral leaflet in the restricted mitral subvalvular space is technically difficult. We successfully performed mitral valve repair in 3 pediatric patients using a modified fixed loop-in-loop technique.
