Alcohol Septal Ablation

Septal Ablation

Cardiologists developed a less invasive method of reducing the outflow obstruction in hypertrophic cardiomyopathy. In this procedure, a few drops of an alcohol-based solution are injected into a small branch of the main artery supplying the thickened heart muscle.

This causes part of the muscle to die (in effect, a small heart attack) and this in turn reduces the obstruction to blood flow.

This procedure is done entirely via a small incision at the top of the leg. Patients typically go home a few days later.

Not every patient will have an appropriate branch of their main artery which supplies only the thickened heart muscle and does not connect with other arteries.
