An 88-year-old woman with a prior history of aortic stenosis and history of valvuloplasty presented with worsening symptoms of heart failure and dizziness. She underwent successful transcatheter aortic valve replacement (TAVR) without complications. Follow-up echocardiograms revealed a small fistula connecting aorta to the right ventricle. The patient was initially asymptomatic but 3 months later developed overload of the right ventricle and heart failure and chose to continue medical therapy. She died of progressive heart failure at 9 months from onset of fistula. Aorto-right ventricular fistula is a rare complication of TAVR with only four cases reported in literature thus far.
一名88岁女性，既往有主动脉瓣狭窄病史及瓣膜成形术史，现出现心力衰竭和头晕症状加重。她成功接受了经导管主动脉瓣置换术（TAVR），无并发症。随访超声心动图显示有一个小瘘管连接主动脉和右心室。患者最初无症状，但3个月后出现右心室负荷过重和心力衰竭，并选择继续药物治疗。她在瘘管形成后9个月死于进行性心力衰竭。主动脉-右心室瘘是TAVR的一种罕见并发症，迄今为止文献中仅报道了4例。
