In patients with the obstructive variant of hypertrophic cardiomyopathy, when symptomatic despite the medical therapy, septal reduction is a common treatment option. Among all the percutaneous approaches, therapeutic septal alcoholization is the most commonly used technique. Non-alcoholic septal reduction techniques have recently emerged as an additional treatment option, generating procedures with more predictable outcomes and lower complication rates. In this report, we describe a case of therapeutic septal reduction with embolization of the target branch using coils with excellent immediate results.
