Aortic Valve Regurgitation - Overview Aortic valve regurgitation is a problem with the aortic valve. The aortic valve allows blood to flow from the heart 's lower left chamber (ventricle) into the aorta and to the body.hen you have aortic valve regurgitation, the aortic valve doesn't close as it should. With each heartbeat, some of the blood leaks back (regurgitates) through the aortic valve into the left ventricle. The body does not get enough blood, so the heart has to work harder to make up for it.

- Certain medical problems or conditions make it more likely that you will develop aortic valve stenosis: 1  Calcium buildup. Aging can cause calcium buildup around the aortic valve, which can make the normally thin and flexible valve flaps thick and stiff. 2  Birth defect.

Aortic valve stenosis Aortic stenosis is abnormal narrowing of the aortic valve. A number of conditions cause disease resulting in narrowing of the aortic valve. When the degree of narrowing becomes significant enough to impede the flow of blood from the left ventricle to the arteries, heart problems develop. The basic mechanism is as follows:

Heart Valve Problems Congenital heart valve problems – Severe valve narrowing can cause a condition called cyanosis, in which the skin becomes bluish, and symptoms of heart failure. Aortic stenosis – Aortic stenosis usually does not cause symptoms until the valve opening narrows to about one-third of normal.

Aortic Valve Disorders Types of Aortic Valve Disorders. There are a few types of aortic valve disorder. 1  Aortic valve stenosis is a narrowing or obstruction of the valve. 2  As shown below, the flaps on the valve cannot open widely enough for sufficient blood to pass.3  This condition accounts for the largest number of surgeries to correct a damaged heart valve.here are a few types of aortic valve disorder. 1  Aortic valve stenosis is a narrowing or obstruction of the valve. 2  As shown below, the flaps on the valve cannot open widely enough for sufficient blood to pass.

- When the leaflets don’t fully open, your heart must work harder to push blood through the aortic valve to your body. Eventually, your heart gets weaker; increasing the risk of heart failure (your heart cannot supply enough blood to your body). Severe aortic stenosis is a very serious problem.

Bicuspid Aortic Disease This condition can lead to a number of complications, including: 1  Leaking of blood back into the heart because the valve doesn't close tightly. Depending on how much leaking occurs, there may be strain on the heart. 2  An inability of the valve to open widely or the development of calcium deposits on the leaflets.

Aortic Valve Disease Aortic valve disease is a condition in which the valve between the main pumping chamber of your heart (left ventricle) and the main artery to your body (aorta) doesn't work properly.Aortic valve disease sometimes may be a condition present at birth (congenital heart disease), or it may result from other causes.Types of aortic valve disease include: 1  Aortic valve stenosis. 2  In this condition, the aortic valve opening is narrowed.3  This narrowing prevents the valve from opening fully, which obstructs blood flow from your heart into your aorta and the rest of your body. 4  Aortic valve regurgitation.ortic valve disease sometimes may be a condition present at birth (congenital heart disease), or it may result from other causes. Types of aortic valve disease include: 1  Aortic valve stenosis. 2  In this condition, the aortic valve opening is narrowed.

Introduction The aortic valve may need to be replaced for two reasons: 1  the valve has become narrowed (aortic stenosis) – the opening of the valve becomes smaller, obstructing the flow of blood out of the heart. 2  the valve is leaky (aortic regurgitation) – the valve allows blood to flow back through into the heart.

Overview With age, heart valves may accumulate deposits of calcium (aortic valve calcification). Calcium is a mineral found in your blood. As blood repeatedly flows over the aortic valve, deposits of calcium can accumulate on the valve's leaflets. These deposits may never cause any problems.

Causes of Aortic valve disease List of causes of Aortic valve disease. Following is a list of causes or underlying conditions (see also Misdiagnosis of underlying causes of Aortic valve disease) that could possibly cause Aortic valve disease includes: Aging - often leads to aortic stenosis. Rheumatic fever.

Aortic Stenosis Aortic stenosis (AS) is a narrowing of the aortic valve in the heart. This valve is located between the left ventricle (lower pumping chamber) and the aorta. The aorta is the largest artery in the body. It transports blood from the heart throughout the body. The aortic valve has three cusps, or flaps, that control the direction and flow of the blood. Aortic stenosis causes obstruction or blockage of blood flow through this valve.

Aortic valve stenosis The heart-weakening effects of aortic valve stenosis may lead to heart failure. Heart failure signs and symptoms include fatigue, shortness of breath, and swollen ankles and feet. Aortic valve stenosis often doesn't produce warning signs or symptoms right away, making it difficult to detect at first.

Diseases of the Aorta If the dissection involves the aortic root, commissural involvement of the aortic valve can lead to aortic regurgitation. Dilation of the root and aortic annulus, without leaflet involvement, can also lead to aortic valve regurgitation. A diastolic murmur is evident in these cases.

Aortic Valve Stenosis What is aortic valve stenosis? Aortic valve stenosis is a narrowing of the aortic valve. The aortic valve allows blood to flow from the heart's lower left chamber (ventricle) into the aorta and to the body. Stenosis prevents the valve from opening properly, forcing the heart to work harder to pump blood through the valve.

Problem: Aortic Valve Stenosis Aortic stenosis is one of the most common and most serious valve disease problems. Aortic stenosis is a narrowing of the aortic valve opening. Aortic stenosis restricts the blood flow from the left ventricle to the aorta and may also affect the pressure in the left atrium.

- Some of the causes include rheumatic disease, endocarditis (infection of the valve), connective tissue diseases (weakening of the tissues that make up the support structures within the body), and congenital diseases. Although the aortic valve may rarely be repaired more often it requires replacement.

Heart Disease: Heart Valve Disease Other causes of valve disease include: coronary artery disease, heart attack, cardiomyopathy (heart muscle disease), syphilis (a sexually transmitted disease), high blood pressure, aortic aneurysms, and connective tissue diseases. Less common causes of valve disease include tumors, some types of drugs, and radiation.

Aortic Valve Replacement Surgery There are several heart valve disorders which stimulate the patient need for AVR. Aortic valve disease can result from a congenital defect. Or, it can result from a serious bacterial infection. However, the two most common diseases that force the patient to undergo valve replacement surgery are:

Bicuspid Aortic Disease An aortic valve that has only two, instead of the normal three, flaps to open and shut the valve. An aortic dilation, aneurysm or dissection (a tear in the wall of the aorta) Deterioration of the valve or the aorta. Rapid changes in blood pressure with activity or stress (labile hypertension)
