Surgical Septal Myectomy Versus Percutaneous Transluminal Alcohol Septal Ablation in Patients With Hypertrophic Obstructive Cardiomyopathy
The aim of this randomized trial is to compare the improvement in exercise capacity among patients with highly symptomatic hypertrophic obstructive cardiomyopathy despite optimal medical treatment who undergo alcohol septal ablation (ASA) or surgical septal myectomy (SSM).
• Age between 40-75 years including 40 and 75 years of age
• HOCM eligible for both SSM and ASA by a heart team (multidisciplinary team) and core lab.
• Left ventricle outflow tract (LVOT) obstruction \> 30mmHg at rest or during physiological provocation by transthoracic echocardiogram
• Symptomatic (New York Heart Association classification (NYHA) \>1 or Canadian Cardiovascular Society (CCS) class \>1) and/or syncope due to HOCM
