Aortic Root Replacement for a TAVR-Induced Aortic Root-to-Right Ventricular Fistula

Alexander P Kossar et al. Ann Thorac Surg. 2020 Oct.

Abstract

Aortic right ventricular fistulae have been thoroughly documented as a rare but potentially serious complication of surgical aortic valve replacement. The risk factors and pathogenesis contributing to this complication with respect to transcatheter aortic valve replacement (TAVR), however, remain far less characterized. We describe a post-TAVR aortic root-to-right ventricular fistula with associated pseudoaneurysm requiring surgical aortic root replacement.

Figure 1.
Computed tomography (CT) imaging revealed a (A) 15.8 × 15.2 mm fluid collection extending from the basal interventricular septum, communicating with the aortic annulus anteriorly and the right ventricular outflow tract posteriorly, suggestive of a fistula. CT reconstruction of the aortic root (stretched-vessel view, B) and associated perpendicular plane (C) further characterized proximal fistula tract termination at the aortic annulus anteriorly.
