Abstract: Transcatheter aortic valve replacement (TAVR) is a minimally invasive procedure for treating aortic stenosis. However, it can lead to complications, such as ventricular septal defects (VSD). Although rare, these defects may result in hemodynamic instability and require intervention. An 82-year-old male with a history of Edwards SAPIEN TAVR and heart failure presented with dyspnea, fatigue, and complete heart block. An electrocardiogram showed a heart block, and a transesophageal echocardiogram revealed a mild paravalvular leak and an outlet VSD at the aortic annulus. Cardiac catheterization confirmed a Qp/Qs ratio of 1.68. After pacemaker implantation, the patient remained stable, and conservative management was pursued with outpatient follow-up. Aorto-right ventricular fistula is a rare late complication of TAVR. Clinicians should consider VSD in patients with complete heart block and a TAVR history, and regular echocardiographic surveillance may be warranted for symptomatic patients.
