经皮冠状动脉介入治疗急性非ST段抬高型心肌梗死合并主动脉瓣Lambl’s赘生物1例Percutaneous coronary intervention for the treatment of non-ST-segment elevation myocardial infarction combined with Lambl's excrescences on the aortic valve:a case report

摘要(Abstract):
Lambl’s赘生物(LEs)是长条形的瓣膜状突起,具有移动性,通常位于心脏瓣膜间的闭合处。这些丝状的突起细长而柔软,在主动脉瓣和二尖瓣附近最为常见,但也可能出现在其他位置。经食管超声心动图检查可用于检测LEs。左心瓣膜闭合线的高压力可能导致内膜撕裂或损伤,从而引发LEs。本病例报道1例急性非ST段抬高型心肌梗死的患者,同时超声心动图在主动脉瓣的无冠瓣上发现LEs。这种特定的解剖位置给经皮冠状动脉介入治疗(PCI)带来了重大挑战,因为需要指引导管与主动脉瓣直接接触,增加了LEs脱落的风险。幸运的是,此次成功地完成了PCI,随访12个月未发生明显的并发症或栓塞事件。
