Alcohol Septal Ablation

Overview: Alcohol septal ablations are a minimally invasive procedure used to treat obstruction in HCM.


Alcohol septal ablation (ASA) is a minimally invasive procedure that is used to treat obstruction due to HCM. In an ASA, a thin, flexible catheter with a balloon tip is threaded through a blood vessel in your groin to the artery that carries blood to your septum. Alcohol is  inserted through the catheter. This will kill some of the heart muscle cells, causing the tissue to shrink. The balloon is then deflated and removed from your body.
