Relevant aortic regurgitation (AR) requires surgical repair at the time of left ventricular assist device (LVAD) implantation to reduce recirculation and ensure adequate forward flow. We report here on a patient with moderate AR in a noncalcified aortic valve and extensive calcification of the ascending aorta. The latter precluded aortic-crossclamping and, thus, surgical intervention on the aortic valve. Although there were no valvular or annular calcifications, a JenaValve transcatheter heart valve was successfully placed transapically with subsequent LVAD implantation in one operation. We believe concomitant transcatheter aortic valve implantation (TAVI) and LVAD implantation is a promising hybrid procedure, even in patients with pure AR.
需要在植入左心室辅助装置 (LVAD) 时进行相关的主动脉瓣反流 (AR) 手术修复,以减少再循环并确保足够的前向血流。我们在此报告一例患有中度 AR 的非钙化主动脉瓣和升主动脉广泛钙化的患者。后者排除了主动脉阻断,因此无法对主动脉瓣进行手术干预。尽管没有瓣膜或瓣环钙化,但仍成功通过经心尖途径植入了 JenaValve 经导管心脏瓣膜,随后在一次手术中植入了 LVAD。我们认为,即使是单纯的 AR 患者,同期行经导管主动脉瓣植入术 (TAVI) 和 LVAD 植入术也是一种很有前途的杂交手术。
