Aneurysm: A bulging of the wall of an artery, vein or heart wall Anti-coagulant: A medication that prevents the forming of blood clots Aorta: The main artery that supplies blood and oxygen to the body. It usually comes off the left ventricle (main pumping chamber) of the heart. Aortic valve: The valve between the aorta and the left ventricle (main pumping chamber). The aortic valve usually has three leaflets. Arrhythmia: An abnormal pattern of the beating of the heart AS: Aortic stenosis, in which the vessel going from the heart to the aorta is narrow or blocked ASD: Atrial septal defect, a hole in the wall that separates the right and left atria (top chambers of the heart) Atrial Septum: The muscular wall between the two collecting chambers of the heart (left atrium and right atrium) Atrio-Ventricular Node (AV Node): Part of the electrical (conduction) pathway of the heart that tells the ventricles when to beat Atresia: absence or abnormal narrowing of a passage Atrium: An upper chamber of the heart. (There are two.) The right atrium collects un-oxygenated (blue) blood from the body. The left atrium collects oxygenated blood from the lungs. AVC or AV Canal Defect: Atrioventricular canal defect, also known as endocardial cushion defect BE: Bacterial endocarditis, an infection of the inner layer and/or valves of the heart, caused by bacteria Blalock-Hanlon: Surgical septostomy performed for palliative treatment of transposition of the great vessels Blood Pressure: The pressure of the blood in the arteries. Systolic blood pressure is the top number (when the heart is contracted). Diastolic blood pressure is the bottom number (when the heart is relaxed).
