Right ventricular failure (RVF) is an unfortunate complication that continues to limit outcomes following durable left ventricular assist device (LVAD) implantation. Despite several 'RVF risk scores' having been proposed, preoperative prediction of post-LVAD RVF remains a guesstimate at best. Current strategies for institution of temporary RVAD support are invasive, necessitate additional re-thoracotomy, restrict postoperative mobilization, and/or entail prolonged retention of prosthetic material in-situ. The authors propose a novel surgical strategy comprising simultaneous implantation of a permanent LVAD and percutaneous TandemHeart® plus ProtekDuo® to provide temporary RVAD support and preempt RVF in patients with impaired RV function.
右心室衰竭(RVF)是一种不幸的并发症,它仍然限制着持久性左心室辅助装置(LVAD)植入后的治疗效果。尽管已经提出了几种“RVF风险评分”,但LVAD植入术后RVF的术前预测充其量仍只是一种猜测。目前建立临时RVAD支持的策略具有侵入性,需要再次开胸,限制术后活动,和/或需要在原位长期保留假体材料。作者提出了一种新颖的手术策略,包括同时植入永久性LVAD和经皮TandemHeart®加ProtekDuo®,以提供临时RVAD支持并预防右心室功能受损患者的RVF。
