Clinical Outcomes Post‐Transcatheter Aortic Valve Replacement in Patients With Hypertrophic Obstructive Cardiomyopathy

Catheterization and Cardiovascular Interventions, Volume 106, Issue 7, Page 3419-3426, December 1, 2025.
ABSTRACT Background Patients with hypertrophic obstructive cardiomyopathy (HOCM) were excluded from all major trials for transcatheter aortic valve replacement (TAVR). “Suicide left ventricle” occurring after TAVR is postulated to occur as a result of chronic pressure overload from fixed obstruction that is acutely relieved after the valve deployment ...
