Alcohol Septal Ablation

Make Appointments & Get Care

What is Alcohol Septal Ablation?

Alcohol septal ablation is a nonsurgical procedure, often for patients with hypertrophic cardiomyopathy (HCM). HCM causes abnormally thick or stiff heart muscles.

In alcohol septal ablation, alcohol is injected into a select coronary artery. Over time, the alcohol shrinks the over-thickened septum (the wall between the two sides of the heart).

Patients sometimes need an implantable loop recorder or defibrillator after the procedure, or a pacemaker.

UR Medicine's Approach


Once you are referred to us, we will perform an evaluation to determine if you are a good candidate for alcohol septal ablation.

What’s included in the evaluation:

  • Review of past medical history and current medical status
  • Collaboration with our Electrophysiology and Advanced Heart Failure physicians for more complex patients
  • Physical exam
  • Family screening
  • Specialized cardiac imaging
  • Assessment of risk for sudden cardiac death
  • Discussion of possible treatment options
  • Referral to Medical Genetics for genetic counseling/possible testing
