A 65 year old patient had his mitral and aortic valves replaced with two Braunwald-Cutter prostheses in 1973. Seven years later, he presented with intermittent aortic insufficiency demonstrated by echocardiography, fluoroscopy and angiography. At emergency surgery, the occluders (poppets) of both prostheses were found within the left ventricular cavity. The valves were excised and replaced with Björk-Shiley prostheses and the patient recovered. Aortic occluder escape is rare and usually fatal. Mitral occluder escape of the Braunwald-Cutter prosthesis has not been described previously.
一名65岁患者于1973年接受了二尖瓣和主动脉瓣置换术，植入了两个布劳恩瓦尔德-卡特人工瓣膜。七年后，经超声心动图、荧光透视检查和血管造影显示，他出现了间歇性主动脉瓣关闭不全。在急诊手术中，发现两个人工瓣膜的封堵器（瓣片）位于左心室腔内。切除这些瓣膜后，换用了比约克-希利人工瓣膜，患者康复。主动脉瓣封堵器脱出很少见，通常是致命的。此前尚未有过关于布劳恩瓦尔德-卡特人工瓣膜二尖瓣封堵器脱出的报道。
