Key result
Large interventricular membranous septal aneurysms can render anatomy unsuitable for TAVR.
Why the study?
Interventricular membranous septal aneurysms are rare but can coexist with aortic valve stenosis, potentially affecting procedural feasibility.
Case Report (n=1)
A large interventricular membranous septal aneurysm can render anatomy unsuitable for TAVR, highlighting the importance of careful pre-procedural anatomical assessment.
Warrants vigilance for septal aneurysms in TAVR planning; single case report leaves open systematic screening needs.
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.

Shirai et al. (2022) conducted a case report in Aortic valve stenosis and large interventricular membranous septal aneurysm (n=1). Transcatheter aortic valve replacement (TAVR) was evaluated on Anatomical suitability for TAVR. A large interventricular membranous septal aneurysm can render the anatomy unsuitable for transcatheter aortic valve replacement.
