Abstract

Leaflet escape in contemporary mechanical valves is an extremely rare and potentially lethal condition. We report the case of a 77-year-old man who presented with embolization of a leaflet from an On-X mitral valve (CryoLife, Kennesaw, GA) with Conform-X Sewing Ring prosthesis (CryoLife) after exercise. The patient recovered completely 6 months after surgery, and he is currently asymptomatic.

摘要

人工机械瓣膜叶瓣脱出极为罕见，但可能致命。我们报告 1 例 77 岁男性患者，因运动后 CryoLife 的 On-X 二尖瓣（Kennesaw，GA）与 Conform-X 缝合环（CryoLife）瓣叶脱出，发生栓塞。患者术后 6 个月完全康复，目前无症状。
