Alcohol septal ablation

Alcohol septal ablation is a minimally invasive treatment procedure used to manage the symptoms of hypertrophic cardiomyopathy (HCM), a condition characterized by the thickening of the heart muscle. The procedure involves the injection of alcohol into the septal artery, leading to a controlled heart attack that reduces the thickness of the heart muscle.

Procedure

The procedure is performed by a cardiologist in a catheterization laboratory. The patient is sedated, and a catheter is inserted into the femoral artery in the groin. The catheter is then guided to the heart using fluoroscopy, a type of X-ray imaging. Once the catheter reaches the septal artery, a small amount of alcohol is injected. This causes a controlled heart attack, which leads to the death of the thickened heart muscle cells. Over time, the dead cells are replaced by scar tissue, which reduces the thickness of the heart muscle and improves the symptoms of HCM.

Indications

Alcohol septal ablation is indicated for patients with hypertrophic cardiomyopathy who have severe symptoms that are not adequately controlled by medication. It may also be considered for patients who are not suitable candidates for septal myectomy, a more invasive surgical procedure.

Risks and Complications

As with any medical procedure, alcohol septal ablation carries some risks. These include the risk of infection, bleeding, damage to the heart or blood vessels, and the possibility of an irregular heart rhythm. In rare cases, the procedure can lead to a heart block, which may require the implantation of a pacemaker.

Effectiveness

Studies have shown that alcohol septal ablation can significantly improve symptoms in patients with hypertrophic cardiomyopathy. However, it may not be as effective as septal myectomy in reducing the thickness of the heart muscle.
