Alcohol Septal Ablation

Alcohol septal ablation (ASA, TASH, Sigwart procedure) is a percutaneous, minimally-invasive treatment performed by an interventional cardiologist to relieve symptoms and improve functional status in severely symptomatic patients with hypertrophic cardiomyopathy (HCM) who meet strict clinical, anatomic and physiologic selection criteria. In carefully selected patients, when performed by an experienced interventional cardiologist, the procedure is successful in relieving symptoms in over 90% of patients.

Hypertrophic cardiomyopathy is a condition of the heart muscle which grows abnormally thick, in the absence of a physiologic cause such as hypertension (high blood pressure) or aortic valve disease. In a large subset of patients with hypertrophic obstructive cardiomyopathy, thickening of the heart muscle in a particular part of the interventricular septum causes obstruction to blood being ejected from the left ventricle.

Alcohol septal ablation is a technique designed to reduce the obstruction to blood being ejected from the heart; the technique creates a small controlled heart attack, killing the area of heart muscle responsible for the obstruction, and eventually causing it to become less thick.

Famous quotes containing the word alcohol:

    The sacrifice to Legba was completed; the Master of the Crossroads had taken the loas’ mysterious routes back to his native Guinea.
    Meanwhile, the feast continued. The peasants were forgetting their misery: dance and alcohol numbed them, carrying away their shipwrecked conscience in the unreal and shady regions where the savage madness of the African gods lay waiting.
    Jacques Roumain (1907–1945)
