We successfully treated a patient who was diagnosed of having hypertrophic obstructive cardiomyopathy after the aortic valve replacement surgery for the concomitant aortic stenosis. We report this first in kind new procedure exclusively developed in our center, Liwen procedure TM (percutaneous intramyocardial septal radiofrequency ablation), for patients with left ventricular outflow tract obstruction in spite of maximal medical therapy. The procedure was performed under transthoracic echo guidance. We discussed the technical details, safety, and effectiveness with corresponding images. The patient did well one year after the procedure without LVOT obstruction or arrhythmia.
