2023年10月4日 · Aortic valve regurgitation — also called aortic regurgitation — is a type of heart valve disease. The valve between the lower left heart chamber and the body's main artery doesn't close tightly. As a result, some of the blood pumped out of the heart's main pumping chamber, called the left ventricle, leaks backward.

Aortic regurgitation is a common form of heart valve disease that ranges from mild to severe. Providers also call this condition aortic insufficiency. Healthcare providers separate aortic regurgitation into two types: Acute. This type happens quickly and suddenly. Chronic. This type happens gradually. The chronic form is more common in the U.S.

2024年5月24日 · What causes aortic regurgitation? Common causes of severe aortic regurgitation are bicuspid valve disease, congenital abnormalities, primary diseases in the ascending aorta or dilated aortic sinuses. Acute aortic regurgitation can be caused from bacterial infections of the heart tissue, after chest trauma or from calcific valve disease.

2023年10月4日 · It can show the aortic valve and the aorta. An echocardiogram can help tell how severe aortic regurgitation is. There are different types of echocardiograms. If a standard test doesn't provide enough information, you may have one called a transesophageal echocardiogram. This type creates pictures of the heart from inside the body.

2019年9月23日 · Chronic severe aortic regurgitation (AR) results in left ventricular (LV) volume and pressure overload, initially leading to compensatory but eventually detrimental myocardial changes, with patients remaining asymptomatic for a long time.

Aortic regurgitation (AR), also known as aortic insufficiency (AI), is the leaking of the aortic valve of the heart that causes blood to flow in the reverse direction during ventricular diastole, from the aorta into the left ventricle. As a consequence, the cardiac muscle is …

2023年7月4日 · Aortic regurgitation (AR), also known as aortic insufficiency, is a form of valvular heart disease in which the integrity of the aortic valve is compromised and leads to inadequate closure of the valve leaflets. A normal aortic valve is comprised of three semilunar cusps that attach to the aortic wall.

Acute aortic regurgitation causes symptoms of heart failure (dyspnea, fatigue, weakness, edema) and cardiogenic shock (hypotension with resultant multisystem organ damage). Chronic aortic regurgitation is typically asymptomatic for years; progressive exertional dyspnea, orthopnea, paroxysmal nocturnal dyspnea, and palpitations develop insidiously.

Acute, severe aortic valve regurgitation needs surgery right away. You may need medicines for a short time to stimulate your heart or to dilate or constrict your blood vessels. In some cases, an infection of the heart valves can cause acute valve regurgitation.

2016年9月17日 · In severe aortic insufficiency the severe leak can lead to enlargement of the heart and symptoms of heart failure requiring aortic valve replacement. Mild and moderate degrees of regurgitation are usually tolerated well and don’t require treatment or cause symptoms. A tight aortic valve is known as aortic stenosis.
