As the indications for implanting left ventricular assist devices have expanded, some patients are qualifying for device removal after myocardial recovery. Whereas explantation has been described for previous generations of devices, no standard procedures have been developed. Removal of centrifugal-flow devices has created the need for a plug to seal the apical ventriculotomy after pump removal. However, no commercially available products are available in the United States. We used a novel technique to fashion a plug from Teflon felt and a Dacron graft to enable minimally invasive explantation of a current-generation centrifugal-flow device in a 33-year-old woman.
随着植入左心室辅助设备的适应证不断扩大，一些心肌恢复后的患者有资格移除设备。虽然已经描述了前几代设备的取出方法，但尚未制定出标准的程序。移除离心流设备后，需要在移除泵后用塞子密封心尖心室切开术。然而，美国没有市售的产品。我们使用一种新颖的技术，用特氟隆毡和涤纶移植物制作一个塞子，以便在一名 33 岁女性中微创取出当前一代的离心流设备。
