Aortic regurgitation Regurgitation Gastroesophageal Reflux Disease (GERD) (AR) is a cardiac Cardiac Total Anomalous Pulmonary Venous Return (TAPVR) condition characterized by the backflow of blood from the aorta Aorta The main trunk of the systemic arteries. Mediastinum and Great Vessels: Anatomy to the left ventricle during diastole Diastole Post-systolic relaxation of the heart, especially the heart ventricles. Cardiac Cycle. Aortic regurgitation Regurgitation Gastroesophageal Reflux Disease (GERD) is associated with an abnormal aortic valve Aortic valve The valve between the left ventricle and the ascending aorta which prevents backflow into the left ventricle. Heart: Anatomy and/or aortic root stemming from multiple causes, commonly rheumatic heart disease Rheumatic Heart Disease Cardiac manifestation of systemic rheumatological conditions, such as rheumatic fever. Rheumatic heart disease can involve any part the heart, most often the heart valves and the endocardium. Rheumatic Fever as well as congenital Congenital Chorioretinitis and degenerative valvular disorders. Acute valvular insufficiency, which rapidly progresses to cardiogenic shock Cardiogenic shock Shock resulting from diminution of cardiac output in heart disease. Types of Shock, is an emergency requiring immediate aortic valve Aortic valve The valve between the left ventricle and the ascending aorta which prevents backflow into the left ventricle. Heart: Anatomy surgery. Chronic AR develops gradually, allowing the left ventricle to adapt to the increased stroke volume Stroke volume The amount of blood pumped out of the heart per beat, not to be confused with cardiac output (volume/time). It is calculated as the difference between the end-diastolic volume and the end-systolic volume. Cardiac Cycle. Thus, echocardiogram Echocardiogram Transposition of the Great Vessels shows left ventricular hypertrophy Hypertrophy General increase in bulk of a part or organ due to cell enlargement and accumulation of fluids and secretions, not due to tumor formation, nor to an increase in the number of cells (hyperplasia). Cellular Adaptation and dilation along with valvular abnormalities. Eventually, congestive heart failure Heart Failure A heterogeneous condition in which the heart is unable to pump out sufficient blood to meet the metabolic need of the body. Heart failure can be caused by structural defects, functional abnormalities (ventricular dysfunction), or a sudden overload beyond its capacity. Chronic heart failure is more common than acute heart failure which results from sudden insult to cardiac function, such as myocardial infarction. Total Anomalous Pulmonary Venous Return (TAPVR) occurs as the left ventricle is unable to handle the hemodynamic overload. Aortic valve replacement Aortic valve replacement Aortic Stenosis is the mainstay of treatment for AR with left ventricular dysfunction.

This audio clip is an example of aortic regurgitation Regurgitation Gastroesophageal Reflux Disease (GERD). It is characterized by a blowing, decrescendo murmur occurring right after S2 S2 Heart Sounds.
Differential diagnoses of AR include the following conditions:
