Abstract
Two cases of fatal left ventricular outflow tract obstruction following mitral valve replacement with low-profile bioprostheses are described. This unfortunate experience shows that correct orientation of the prosthesis is mandatory also when using low-profile bioprosthetic valves to avoid this complication, particularly in patients with a small left ventricular cavity.
摘要
本文描述了两例使用低轮廓生物瓣膜进行二尖瓣置换术后发生致命性左心室流出道梗阻的病例。这一不幸的经历表明，即使使用低轮廓生物瓣膜，假体的正确定位也是必不可少的，以避免这种并发症，特别是在左心室腔较小的患者中。
