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.

摘要

我们报告一例肥厚型梗阻性心肌病（HOCM）与冠状动脉疾病同时进行经皮治疗的病例。心脏导管检查显示左心室流出道压力阶差（LVOTPG）为130 mmHg，且在第一大间隔支部位存在明显的左前降支（LAD）狭窄。通过向该分支注射乙醇消除了LVOTPG。随后，在LAD植入了冠状动脉支架。由于未来可能需要重复间隔消融，因此选择了线圈支架。使用线圈支架同时治疗HOCM和LAD狭窄被认为是安全有效的。
