Abstract Introduction: Predictors of arrhythmias and sudden cardiac death in patients with hypertrophic cardiomyopathy (HCM) have been identified. However, they have not been validated after alcohol septal ablation (ASA). Data to predict the occurrence of arrhythmia after the procedure are not certain. Objectives: To retrospectively analyze patients who underwent ASA and to determine the predictors of post-op ventricular arrhythmia. Patients and Methods: We retrospectively enrolled 53 consecutive patients with HCM who underwent ASA procedure due to symptomatic left ventricular outflow […]
