We report a case in which the DuraHeart (Terumo Heart, Ann Arbor, MI, USA) was successfully removed despite a low ejection fraction. A 33-year-old man who suffered from dilated cardiomyopathy underwent implantation of the DuraHeart. The assist flow decreased to less than 1.0 l/min 3 months after the implantation. Echocardiography demonstrated a low left ventricular ejection fraction (26 %) and left ventricular dilatation (64 mm). Right heart catheterization revealed a cardiac index of 2.9 l/min/m(2) with a DuraHeart flow of 0.7 l/min. The patient underwent DuraHeart explantation without cardiopulmonary bypass. He was stable at 10 months post-explant.
我们报告了一例尽管射血分数较低，但DuraHeart（美国密歇根州安阿伯市泰尔茂心脏公司）仍成功移除的病例。一名患有扩张型心肌病的33岁男性接受了DuraHeart植入术。植入后3个月，辅助血流降至每分钟1.0升以下。超声心动图显示左心室射血分数较低（26%）且左心室扩张（64毫米）。右心导管检查显示心脏指数为每分钟2.9升/平方米，DuraHeart血流为每分钟0.7升。该患者在未进行体外循环的情况下接受了DuraHeart移除术。移除术后10个月，他情况稳定。
