BATMAN is a new technique to prevent left ventricular outflow tract (LVOT) obstruction from transcatheter mitral valve replacement (TMVR) by deploying the transcatheter heart valve from the apex through a perforation of the anterior mitral valve leaflet. The risks of uncontrolled balloon dilatation of the anterior mitral valve leaflet include extension of the tear superiorly into the aorto-mitral curtain or laterally to avulse the trigone from the annulus. Percutaneous laceration of the anterior mitral leaflet, pre-emptive alcohol septal ablation, and transatrial leaflet resection are alternative strategies that prevent LVOT obstruction from TMVR.
BATMAN是一种通过经心尖穿过二尖瓣前叶穿孔来部署经导管心脏瓣膜，以预防经导管二尖瓣置换术（TMVR）导致左心室流出道（LVOT）梗阻的新技术。二尖瓣前叶不受控制的球囊扩张风险包括撕裂口向上延伸至主动脉二尖瓣间隔或向外侧延伸以从瓣环撕脱三角区。二尖瓣前叶的经皮撕裂、预防性酒精室间隔消融和经心房瓣叶切除术是预防TMVR导致LVOT梗阻的替代策略。
