This report describes the case of a 64-year-old woman with a previous diagnosis of obstructive hypertrophic cardiomyopathy who underwent surgical myectomy but who had a persistent midventricular residual gradient. The patient was symptomatic despite medical treatment and chose to undergo percutaneous radiofrequency (RF) ablation focused on the gradient. RF delivery was performed, and the gradient was reduced from the initial 105/68 mm Hg (during Valsalva maneuver/at rest before ablation) to 24/10 mm Hg. This reduction was sustained for the next 12 months. Percutaneous RF ablation may be a reasonable option for second surgical myectomy, and the protocol can be easily reproduced.
