Alcohol septal ablation (ASA) is an established alternative to surgical myectomy for the relief of left ventricular outflow tract obstruction in patients with hypertrophic obstructive cardiomyopathy1 and has been shown to improve New York Heart Association class and exercise tolerance, and to reduce outflow tract gradients.2
ASA is a percutaneous technique necessitating catheterisation of the left coronary artery. To identify the area of myocardium to be ablated, a proximal septal branch is wired, and an …
