Abstract

A 72-year-old woman with a 6-month history of severe mitral valve regurgitation presented at our institution with dyspnea (NYHA II-III) and left ventricular impairment (LVEF 50%). Echocardiography showed P2-P3 prolapse with chordal rupture. A posterior mitral valve repair was performed using the loop technique through a minimally invasive approach. Only trivial postoperative regurgitation was observed. This video tutorial shows demonstrates our technique for this procedure and shows how we created self-made loop neochords.

摘要

一名72岁女性，有6个月严重二尖瓣反流病史，因呼吸困难（纽约心脏协会II-III级）和左心室功能障碍（左心室射血分数50%）前来我院就诊。超声心动图显示P2-P3脱垂伴腱索断裂。通过微创方法采用套圈技术进行二尖瓣后叶修复。术后仅观察到微量反流。本视频教程展示了我们进行该手术的技术以及我们自制套圈新腱索的方法。
