Nonalcoholic percutaneous transluminal septal ablation for hypertrophic cardiomyopathy with obstruction

Abstract

The procedure presented describes an alternative way to avoid this rare but serious complication. By positioning a covered stent in the left anterior descending artery at the origin of the septal perforator branch, mechanical occlusion of the perforator branch is achieved. This results in focal myocardial infarction as evidenced by the relatively modest elevation in creatine kinase compared with alcoholic percutaneous transluminal septal myocardial ablation and thinning of the ventricular septum. Although in-stent restenosis as well as thrombosis should be considered, these complications are better treatable compared with alcohol leakage in the left anterior descending artery. Therefore, this new technique could be a valuable alternative in treating obstructive HC.
