Aortic regurgitation Regurgitation Gastroesophageal Reflux Disease (GERD) (AR) is a cardiac 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 Shock Shock is a life-threatening condition associated with impaired circulation that results in tissue hypoxia. The different types of shock are based on the underlying cause: distributive (↑ cardiac output (CO), ↓ systemic vascular resistance (SVR)), cardiogenic (↓ CO, ↑ SVR), hypovolemic (↓ CO, ↑ SVR), obstructive (↓ CO), and mixed. 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 Left ventricular hypertrophy Enlargement of the left ventricle of the heart. This increase in ventricular mass is attributed to sustained abnormal pressure or volume loads and is a contributor to cardiovascular morbidity and mortality. Hypertension and dilation along with valvular abnormalities. Eventually, congestive heart failure Congestive heart failure Congestive heart failure refers to the inability of the heart to supply the body with normal cardiac output to meet metabolic needs. Echocardiography can confirm the diagnosis and give information about the ejection fraction. Congestive Heart Failure occurs as the left ventricle is unable to handle the hemodynamic overload. Aortic valve Aortic valve The valve between the left ventricle and the ascending aorta which prevents backflow into the left ventricle. Heart: Anatomy replacement 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:
