What causes mitral incompetence?

The common causes of organic (primary) MR include prolapse syndrome, flail leaflet, rheumatic heart disease, coronary artery disease (CAD), infective endocarditis, certain drugs (some anorectic drugs), and collagen vascular disease.

What is the pathology of mitral valve disease?

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

What causes incompetent heart valve?

Heart valve disease occurs when your heart’s valves do not work correctly. Common causes of valve disease include rheumatic fever, birth defects, degeneration over time and infection. This can be caused by valvular stenosis or valvular insufficiency.

What causes mitral valve stenosis?

The main cause of mitral valve stenosis is an infection called rheumatic fever, which is related to strep infections. Rheumatic fever — now rare in the United States, but still common in developing countries — can scar the mitral valve. Left untreated, mitral valve stenosis can lead to serious heart complications.

What is the most common heart valve disorder?

Mitral valve prolapse: The most common heart valve abnormality and the No. 1 cause for mitral regurgitation, this is when the mitral valve doesn’t open and close properly.

What is a mitral valve leaflet?

The mitral valve has two leaflets. The anterior leaflet has a semi-circular shape and attaches to two fifths of the annular circumference. There is continuity between the anterior leaflet of the mitral valve and the left and non-coronary cusp of the neighboring aortic valve, referred to as the aortic-mitral curtain.

What causes mitral valve insufficiency?

Causes of mitral insufficiency. Most mitral valve insufficiency is due to distortion of the free edge. Most often this is associated with deposits of tissue. Normally, when the heart beats, the ventricles pump the blood out to the arteries.

What does mitral valve insufficiency mean?

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.

What makes mitral valve prolapse worse?

Sometimes, symptoms that mitral valve prolapse is getting worse occur from lifestyle changes or actions that the sufferer has taken with their diet. Eating foods to avoid with mitral valve prolapse, for example, can worsen or trigger symptoms.

Do I need mitral valve replacement?

If your condition is mild, you may not need surgery. However, your mitral valve may eventually need to be repaired or replaced. In some cases, doctors may recommend mitral valve repair or mitral valve replacement even if you’re not experiencing symptoms.
