TAVI in Complex Dual-Level Obstruction: A Case of Severe Aortic Stenosis and Subaortic Membrane.

Abstract

This case addresses the challenges of treating patients with both severe aortic stenosis and subaortic stenosis. In this combined condition, transcatheter aortic valve implantation (TAVI) remains an off-label application, particularly in the presence of a subaortic membrane. Our multimodal imaging approach that incorporates echocardiography, cardiac computed tomography, and fluoroscopic guidance demonstrates the successful application of TAVI in a high-risk clinical scenario. The results underscore the potential of TAVI as a viable alternative to traditional surgical aortic valve replacement for patients with dual-level obstruction who are not candidates for open surgery.
