Abstract

We report a case of simultaneous percutaneous treatment of hypertrophic obstructive cardiomyopathy (HOCM) and coronary artery disease. Cardiac catheterization revealed a left ventricular outflow tract pressure gradient (LVOTPG) of 130 mmHg and a significant left anterior descending artery (LAD) stenosis at the site of the 1st major septal branch. The LVOTPG was eliminated by injection of ethanol into the branch. Subsequently, a coronary stent was implanted in the LAD. A coil stent was selected due to possibility of repeat septal ablation in the future. Simultaneous treatment of HOCM and LAD stenosis is considered safe and effective using a coil stent.
