摘要

经导管二尖瓣置换术是一种混合策略，包括将患者置于体外循环和直接将经导管瓣膜植入钙化环中以治疗二尖瓣环钙化。我们报告了一种罕见的现象，即用于二尖瓣置换术的经导管心脏瓣膜假体的小叶收缩前移导致左心室流出道阻塞。尽管在经导管二尖瓣置换术中有报道，但我们认为这是经导管二尖瓣替换术后左心室流出道梗阻的首次报道，并讨论了处理前的危险因素。

Systolic anterior motion of a transatrial transcatheter mitral valve replacement causing left ventricular outflow tract obstruction.

Transatrial transcatheter mitral valve replacement is a hybrid strategy involving placing the patient on cardiopulmonary bypass and direct implantation of a transcatheter valve in a calcified annulus for mitral annular calcification. We report a rare phenomenon of systolic anterior motion of the leaflets of a transcatheter heart valve prosthesis used for mitral valve replacement causing left ventricular outflow tract obstruction. Although reported in transcatheter mitral valve replacement, we believe this is the first report of left ventricular outflow tract obstruction after transatrial mitral valve replacement and discuss the pre-disposing risk factors.
