CT-Guided Transcatheter Aortic Valve Replacement in Bicuspid Aortic Stenosis With a Large Membranous Ventricular Septal Aneurysm: Challenges in Annular Sizing and Valve Selection.
Membranous ventricular septal aneurysm (MSA) is an uncommon anatomical finding that may significantly alter the geometry of the aortic annulus and left ventricular outflow tract, creating challenges for transcatheter aortic valve replacement (TAVR). We report the case of a 78-year-old woman with symptomatic severe bicu...
