Abstract:
An interventricular membranous septal aneurysm, though rare, can coexist with aortic valve stenosis. In this report, we present an unsuitable anatomy for transcatheter aortic valve replacement (TAVR) due to large interventricular membranous septal aneurysm. This case suggests that the feasibility of TAVR would depend on the location and size of the aneurysm and its relationship with the aortic root.
