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.
