Aortic valve perforation following transcoronary ablation of septal hypertrophy.

We report the case of a 47-year-old man with hypertrophic obstructive cardiomyopathy who underwent transcoronary ablation of septal hypertrophy and developed severe aortic regurgitation after the procedure. Intra-operatively, we found a wide perforation of the noncoronary cusp, and performed aortic valve replacement.
