3D print and multi-modality imaging guided transcatheter closure of multiple left ventricular pseudoaneurysms

Abstract

Left ventricular pseudoaneurysm (PSA) after surgical aortic valve replacement (AVR) is a known but uncommon complication. It is associated with risks such as thromboembolism and life-threatening rupture. Surgical repair has traditionally been utilized in low-risk patients but transcatheter closure has become a promising therapeutic option. This case report describes the utility of multimodality imaging in pre-, intra-, and post-procedural evaluation of transcatheter PSA closure and is among the first to demonstrate the utility of 3D print model.
