A 74-year-old woman with failed mitral surgical repair underwent transcatheter mitral valve-in-ring replacement. Pre-procedural assessment highlighted a substantial risk for valve misalignment and left ventricular outflow obstruction. Electrosurgical laceration of the anterior mitral leaflet to prevent outflow obstruction (LAMPOON) technique and transapical wire externalization for valve deployment were successfully employed to prevent these complications.
一名二尖瓣手术修复失败的74岁女性接受了经导管二尖瓣环内瓣膜置换术。术前评估突出显示了瓣膜错位和左心室流出道梗阻的重大风险。成功采用二尖瓣前叶电外科撕裂以防止流出道梗阻（LAMPOON）技术和经心尖导线外置以进行瓣膜植入，从而预防了这些并发症。
