Septal Ablation

Septal ablation (also referred to as alcohol septal ablation) is a minimally invasive technique that treats a heart condition called hypertrophic obstructive cardiomyopathy. This is an inherited (genetic) structural heart condition in which certain parts of the heart are thicker than they should be, which can cause fatigue, shortness of breath and a decreased quality of life.

The cardiologists at Weill Cornell Medicine are experts in the septal ablation procedure. Many patients benefit from this procedure because it reduces symptoms, improves quality of life and reduces future complications.

With compassionate and expert care from Weill Cornell Medicine cardiologists, our patients achieve the best possible health and well-being.

Septal Ablation

First, your cardiologist will determine if this procedure is right for you and what you can expect.

During this procedure, you will be awake and given medications to help you relax as well as reduce the likelihood of blood clots (mass of blood when cells in the blood stick together) during your procedure. A numbing medication is applied to your skin in your groin area and a small incision (cut) is made. Next, a catheter (long, thin tube) is inserted into the incision, into an artery or vein and led to your heart.

During the procedure, your cardiologist will use imaging tools to be sure the catheter is in the right place and measure your heart. Next, a small amount of alcohol is released into the artery to destroy part of the thickened muscle. This may cause some discomfort, but will improve quickly. Next, your cardiologist will remove the tubes through your groin and bandage the incision.

You will spend several hours in a recovery room lying flat. This will prevent bleeding and help your healing. You will then stay under cardiac care for a few days to monitor your recovery.

When you return home, you will be able to return to light activity. Your doctor will discuss when to resume exercising and other activities. Most patients notice an immediate improvement of their symptoms after the procedure.
