Minimally invasive left ventricular assist device (LVAD) implantation with the HeartWare VAD (HVAD) has been reported lately as an alternative approach to median sternotomy due to its favorable results regarding sternal wound complications, mediastinitis, postoperative bleeding, and right ventricular failure (RVF). Relevant aortic regurgitation is a cardiac comorbidity that requires surgical repair at the time of LVAD implantation to reduce recirculation and ensure adequate forward flow. We herein report on a patient with severely reduced left ventricular function due to ischemic cardiomyopathy, moderate aortic regurgitation, and a reduced right ventricular function. We performed minimally invasive HVAD implantation with concomitant transapical transcatheter aortic valve replacement. We believe this hybrid procedure could potentially reduce the risk for post-LVAD RVF because it preserves the pericardial geometry and obviates the need for cardioplegic arrest.
最近有报道称,采用HeartWare心室辅助装置(HVAD)进行微创左心室辅助装置(LVAD)植入术是一种替代正中胸骨切开术的方法,因为其在胸骨伤口并发症、纵隔炎、术后出血和右心室衰竭(RVF)方面取得了良好的效果。相关的主动脉瓣反流是一种心脏合并症,在LVAD植入时需要进行手术修复,以减少再循环并确保足够的前向血流。我们在此报告一名因缺血性心肌病导致左心室功能严重降低、中度主动脉瓣反流和右心室功能降低的患者。我们进行了微创HVAD植入术并同时进行经心尖经导管主动脉瓣置换术。我们认为这种联合手术可能会降低LVAD术后RVF的风险,因为它保留了心包的几何形状,并且无需心脏停搏。
