Overview Mitral valve prolapse and regurgitation. When your heart is working properly, the mitral valve closes completely during contraction of the left ventricle and prevents blood from flowing back into your heart's upper left chamber (left atrium).he bulging may keep the valve from closing tightly. When blood leaks backward through the valve, it's called mitral valve regurgitation. This may not cause problems if only a small amount of blood leaks back into the atrium.

Background The pulmonic valve is normally a thin tricuspid structure that prevents blood from regurgitating into the right ventricle once ejected into the low-pressure pulmonary circulation. Pulmonic regurgitation refers to retrograde flow from the pulmonary artery into the right ventricle during diastole. Physiologic (trace-to-mild) pulmonic regurgitation is present in nearly all individuals, particularly in those with advanced age.

Mitral valve regurgitation In mitral valve prolapse, the leaflets of the mitral valve bulge (prolapse) into the left atrium like a parachute during the heart's contraction. Sometimes mitral valve prolapse causes blood to leak back into the atrium from the ventricle, which is called mitral valve regurgitation.

Overview Mitral valve prolapse (MVP) occurs when the valve between your heart's left upper chamber (left atrium) and the left lower chamber (left ventricle) doesn't close properly.

Aortic Valve Regurgitation  [en EspaÃ±ol] What is aortic valve regurgitation? 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. When the heart rests between beats, the valve closes to keep blood from flowing backward into the heart.

Human Physiology/Print Version Mitral Valve Prolapse. In MVP, when the left ventricle contracts, one or both flaps of the mitral valve flop or bulge back (prolapse) into the left atrium. This can prevent the valve from forming a tight seal. As a result, blood may leak from the ventricle back into the atrium. The backflow of blood is called regurgitation.

- The mitral valve regulates the flow of blood from the upper-left chamber (the left atrium) to the lower-left chamber (the left ventricle). Three diseases of the mitral valve are mitral valve prolapse, mitral regurgitation, and mitral stenosis.

Tricuspid regurgitation The tricuspid valve separates the right lower heart chamber (the right ventricle) from the right upper heart chamber (right atrium). Tricuspid regurgitation is a disorder in which this valve does not close tight enough. This problem causes blood to flow backward into the right upper heart chamber (atrium) when the right lower heart chamber (ventricle) contracts. An increase in size of the right ventricle is the most common cause of this condition.

What are mitral stenosis, mitral regurgitation and mitral valve prolapse? Mitral stenosis, mitral regurgitation and mitral valve prolapse are all defects of the heart's mitral valve. The heart is a two-sided pump with four chambers. Four valves control the flow of blood through the heart.roblems with the mitral valve include: 1  Mitral stenosis: The leaflets are fused, are too thick, or there is some other structural defect in the valve leaflets. 2  Sometimes, mitral stenosis occurs as a result of surgery to repair an abnormal mitral valve.

- What Is Mitral Regurgitation? Mitral regurgitation (MR) occurs when the heart's mitral valve does not close completely, allowing blood to regurgitate (or leak) through the valve when it should be closed. Here is a brief review of the heart's chambers and valves.

- Mitral regurgitation is where blood leaks back through the mitral valve in the heart as the valve does not close properly. This increases the pressure in the left atrium and in the blood vessels coming from the lungs. This may lead to various problems and symptoms, depending on the severity of the leak.itral valve prolapse. This is also called floppy mitral valve. In this condition the valve is slightly deformed and bulges back into the left atrium when the ventricle contracts. This can let a small amount of blood leak back into the left atrium. As many as 1 in 20 people have some degree of mitral valve prolapse.

- Mitral Valve Insufficiency/Regurgitation. 1  Overview: Mitral valve insufficiency/regurgitation is a disease in which the mitral valve does not close completely, causing blood to flow backward instead of forward through the valve. 2  Mitral valve insufficiency/regurgitation may develop in response to a number of conditions.

Problem: Pulmonary Valve Regurgitation Pulmonary regurgitation (PR, also called pulmonic regurgitation) is a leaky pulmonary valve. This valve helps control the flow of blood passing from the heart to the lungs. A leaky pulmonary valve allows blood to flow back into the heart chamber before it gets to lungs for oxygen.

- The bicuspid aortic valve may not be completely effective at stopping blood from leaking back into the heart. This is called aortic regurgitation. The aortic valve may also become stiff and not open up as well, causing the heart to have to pump harder than usual to get blood past the valve (aortic stenosis).

Aortic Valve Disease Definition. 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.

- Mitral regurgitation is leakage of blood backward through the mitral valve each time the left ventricle contracts. 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.

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.

Mitral valve regurgitation Mitral regurgitation is the most common type of heart valve disorder. Blood that flows between different chambers of your heart must flow through a valve. The valve between the two chambers on the left side of your heart is called the mitral valve.

Heart Valve Disease 1 Also called regurgitation, incompetence, or leaky valve, this occurs when a valve does not close tightly. 2  If the valves do not seal, some blood will leak backwards across the valve. 3  As the leak worsens, the heart has to work harder to make up for the leaky valve, and less blood may flow to the rest of the body.

Causes and Treatment of Mitral Regurgitation View All. Mitral regurgitation occurs when the heart's mitral valve does not close properly, allowing blood to leak (regurgitate) back into the heart chamber. Mitral regurgitation is not only the most common of heart valve abnormality, it can be one of the most challenging to evaluate and treat.

Mitral Valve Regurgitation - Overview Mitral valve regurgitation means that one of the valves in your heart-the mitral valve-is letting blood leak backward into the heart.Heart valves work like one-way gates, helping blood flow in one direction between heart chambers or in and out of the heart. The mitral valve is on the left side of your heart.It lets blood flow from the upper to the lower heart chamber. 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.he mitral valve is on the left side of your heart. It lets blood flow from the upper to the lower heart chamber.

Mitral insufficiency Mitral regurgitation is sometimes called mitral insufficiency or mitral incompetence. In mitral regurgitation the valve does not close properly. This causes blood to leak back (regurgitate) into the left atrium when the left ventricle contracts. Basically, the more open the valve remains, the more blood regurgitates, the more severe the problem.
