Based on the success of the pneumatically powered HeartMate (Thermo Cardiosystems Inc, Woburn, MA) left ventricular assist device, researchers at the Texas Heart Institute have begun conducting clinical studies of the vented electric model in bridge-to-transplantation procedures. Like the pneumatic device, the electric device is implanted intraperitoneally, but the blood pump is powered through a percutaneous lead that is connected to two rechargeable batteries. The batteries are worn in a shoulder holster; thus, patients are not tethered to a control console and are fully mobile. Two patients are currently undergoing left ventricular support with the vented electric HeartMate (duration of support, 315 days and 112 days) as they await cardiac transplantation, and they seem to be medically fit for outpatient care and follow-up. This technology may eventually allow selected patients to receive long-term support as a substitute for cardiac transplantation.
基于气动式HeartMate（美国马萨诸塞州沃本市的热控心血管系统公司）左心室辅助装置的成功，得克萨斯心脏研究所的研究人员已开始在心脏移植桥接手术中对通风电动模型进行临床研究。与气动装置一样，电动装置植入腹腔内，但血泵通过经皮导线供电，该导线连接到两个可充电电池。电池佩戴在肩带中；因此，患者无需连接到控制台，可完全自由活动。目前有两名患者在等待心脏移植期间，正使用通风电动HeartMate进行左心室支持（支持时长分别为315天和112天），他们在医学上似乎适合门诊护理和随访。这项技术最终可能使部分患者获得长期支持，以替代心脏移植。
