Mitral Valve Regurgitation - Cause Acute mitral valve regurgitation occurs when the mitral valve or one of its supporting structures ruptures suddenly, creating an immediate overload of blood volume and pressure in the left side of the heart. Your heart doesn't have time to adjust to the increased volume and pressure of blood (as it does in chronic MR).

- Aortic valve regurgitation — or aortic regurgitation — is a condition that occurs when your heart's aortic valve doesn't close tightly.Aortic valve regurgitation allows some of the blood that was just pumped out of your heart's main pumping chamber (left ventricle) to leak back into it.The leakage may prevent your heart from efficiently pumping blood to the rest of your body. As a result, you may feel fatigued and short of breath.ortic valve regurgitation allows some of the blood that was just pumped out of your heart's main pumping chamber (left ventricle) to leak back into it.

Problem: Heart Valve Regurgitation Regurgitation is the name for leaking heart valves. Sometimes the condition is minor and may not require treatment, but other times valve regurgitation places a strain on the heart. It can cause the heart to work harder to pump the same amount of blood. Regurgitation occurs when: 1  Blood flows back through the valve as the leaflets are closing. 2  Blood leaks through the leaflets when they should be completely closed.

- Mitral regurgitation is the most common complication of mitral valve prolapse. MR may be acute (due to ruptured chordae tendineae causing flail mitral valve leaflets) or chronic. Sequelae of MVP with MR include heart failure, infective endocarditis, and atrial fibrillation (AF) with thromboembolism.

Mitral Regurgitation Mitral regurgitation (MR) is incompetency of the mitral valve causing flow from the left ventricle (LV) into the left atrium during ventricular systole.MR can be primary (common causes are mitral valve prolapse and rheumatic fever) or secondary to LV dilation or infarction.Complications include progressive heart failure, arrhythmias, and endocarditis. Symptoms and signs include palpitations, dyspnea, and a holosystolic apical murmur.itral regurgitation (MR) is incompetency of the mitral valve causing flow from the left ventricle (LV) into the left atrium during ventricular systole.

Tricuspid Regurgitation The tricuspid valve separates the right lower heart chamber (the right ventricle) from the right upper heart chamber (right atrium). The most common cause of tricuspid regurgitation is enlargement of the right ventricle, which pumps blood to the lungs, where it picks up oxygen.

Problem: Heart Valve Regurgitation A leaking (or regurgitant) aortic valve allows blood to flow in two directions. Oxygen-rich blood either flows out through the aorta to the body — as it should — but some flows backwards from the aorta into the left ventricle when the ventricle relaxes.

Problem: Heart Valve Regurgitation Mitral regurgitation is leakage of blood backward through the mitral valve each time the left ventricle contracts. Aortic valve regurgitation may stem from a congenital heart defect, complications of an infection or other more rare causes.

Overview This can lead to blood leaking backward (regurgitating) into the right atrium. Tricuspid valve regurgitation in children is usually caused by heart disease present at birth (congenital heart disease), and Ebstein's anomaly is the most common congenital heart disease that causes the condition.

Mitral Valve Regurgitation - Overview See a picture of mitral valve regurgitation . When the mitral valve is damaged-for example, by an infection-it may no longer close tightly. This lets blood leak backward, or regurgitate, into the upper chamber. Your heart has to work harder to pump this extra blood. Small leaks are usually not a problem.

Overview Mitral valve regurgitation — also called mitral regurgitation, mitral insufficiency or mitral incompetence — is a condition in which your heart's mitral valve doesn't close tightly, allowing blood to flow backward in your heart.

Mitral Valve Regurgitation - Overview Instead of a slow leak, blood builds up quickly in the left side of the heart. Your heart doesn't have time to adjust to this sudden buildup of blood the way it does with the slow buildup of blood in chronic regurgitation. Common causes of acute regurgitation are heart attack and a heart infection called endocarditis. What are the symptoms?

- Mitral regurgitation occurs when the valve between the upper and lower chambers on the left side of the heart does not close properly. Mitral regurgitation can be caused by progressive structural changes in the leaflets of the mitral valve, certain infectious diseases and some heart attacks.

Heart Failure  In-Depth Report Aortic regurgitation is where blood leaks back through the aortic valve. This is because the valve does not close properly. With each heartbeat, more blood than usual enters the left ventricle and so it needs to work harder.Mild regurgitation may not cause symptoms.he aortic valve lies between the left ventricle and the aorta. When the left ventricle relaxes, the aortic valve closes and the mitral valve opens. This allows more blood into the ventricle, ready for the next heartbeat. Aortic regurgitation is sometimes called aortic incompetence or a leaky aortic valve.

Heart Murmur Symptoms, Causes, Treatments, and Surgery 1 Calcification of a valve may also result in stenosis. 2  This causes the heart muscle to work harder to push blood through the narrowed opening and possible heart failure. 3  Valve regurgitation (or insufficiency) is a valve that leaks causing blood to pass backward against the normal blood flow pattern in the heart.

Mitral Valve Regurgitation Mitral valve regurgitation symptoms. When mitral regurgitation is severe, the blood backs up into the lungs. This leads to congestive heart failure, which causes fatigue, fluid retention and shortness of breath. Additionally, the leakiness of the valve burdens the heart and causes it to work harder.

Causes and effects of heart valve disease In some cases, medicine can be used to treat the condition; in others, surgery may be necessary. Bacterial endocarditis -- Bacterial endocarditis is a bacterial infection that can affect the valves of the heart causing deformity and damage to the leaflets of the valve(s).Effects: Regurgitation occurs when blood flows back into the valve as the leaflets close or leaks through the leaflets after they are closed.eart valve disease occurs when one or more of the valves is damaged. Causes: Degenerative valve disease -- This is a common cause of valvular degeneration.

Tricuspid Regurgitation (Tricuspid Valve Insufficiency) The most common cause of tricuspid regurgitation is right ventricle dilation. The right ventricle (the lower right-hand chamber) is responsible for pumping blood from your heart to your lungs. When the right ventricle is forced to work extra hard at this task, it can dilate (or become larger) to compensate.

Problem: Heart Valve Regurgitation Mitral regurgitation is leakage of blood backward through the mitral valve each time the left ventricle contracts. Watch an animation of mitral valve regurgitation. A leaking mitral valve allows blood to flow in two directions during the contraction. Some blood flows from the ventricle through the aortic valve — as it should — and some blood flows back into the atrium.

Mitral Valve Regurgitation Mitral Valve Regurgitation. The mitral valve is on the left side of the heart. It lets blood flow from the upper to the lower heart chamber. Mitral valve regurgitation is diagnosed when the mitral valve in the heart does not close well, which causes blood to leak back from the left ventricle into the left atrium. Mitral valve regurgitation forces the heart to work harder to pump extra blood out of the heart.
