Alcohol Septal Ablation (ASA)

Percutaneous ablation may be considered in hypertrophic cardiomyopathy (HCM) with left ventricular outflow tract obstruction, limited drug treatment, and anatomical assessment showing the presence of an accessible septal branch. The decision is based on a comprehensive assessment of symptom severity, resting/provoked gradient, branch anatomical feasibility, previous treatment response, cardiopulmonary function, and overall risk by a specialist team.
