Abstract:
Membranous ventricular septum aneurysm (MVSA) is extremely rare, especially when coexisting with aortic stenosis (AS), and reports regarding the available treatment for MVSA with AS are limited. Aortic valve replacement (AVR) can be challenging because of anatomical reasons. In this case report, a patient with MVSA and severe AS was treated with AVR with the sutureless Perceval bioprosthesis. After implantation, no paravalvular leakage was detected in echocardiography, and no other postoperative complications were observed. Postoperative electrocardiography-gated computed tomography revealed no contrast enhancement for MVSA. The MVSA was closed by the Perceval bioprosthetic valve. Thus, patients with simultaneous MVSA and AS may be effectively treated with AVR using a Perceval bioprosthesis.
