Alcohol septal ablation is a percutaneous alternative to surgical myotomy-myomectomy for symptomatic patients who have hypertrophic cardiomyopathy (HCM) and left ventricular outflow tract (LVOT) obstruction.

Here we discuss the mechanics of the procedure itself and examine its place in clinical practice, highlighting the importance of appropriate patient selection.
