Commissural fusion of the native aortic valve in a patient with a continuous flow left ventricular assist device (LVAD) is a known phenomenon. This may result in aortic insufficiency (AI) leading to symptomatic heart failure. In patients with AI at the time of LVAD implantation, repairing, or replacing the aortic valve is advisable. We describe a patient who had a severe dilated cardiomyopathy and moderate AI who underwent implantation of an LVAD and aortic valve replacement with a bioprosthesis that subsequently developed commissural fusion which was found at the time of heart transplantation. This case highlights the conundrum of the management of AI in patients requiring LVAD support.
在植入连续血流左心室辅助装置(LVAD)的患者中,天然主动脉瓣的瓣叶融合是一种已知现象。这可能导致主动脉瓣关闭不全(AI),进而引发有症状的心力衰竭。对于在植入LVAD时就存在AI的患者,建议修复或置换主动脉瓣。我们描述了一名患有严重扩张型心肌病和中度AI的患者,该患者接受了LVAD植入及生物瓣主动脉瓣置换术,随后在心脏移植时发现发生了瓣叶融合。该病例凸显了需要LVAD支持的患者中AI管理的难题。
