Mitral valve regurgitation, also known as mitral valve insufficiency or mitral valve incompetence, is a valvulopathy that describes leaking of the mitral valve during . Insufisiensi Mitrai. Insufisiensi mitral dapat disebabkan oleh deformitas daun- daun katup, deformitas anulus mitral, atau gangguan pada khorda tendinae dan . Mitral regurgitation (MR), Mitral insufficiency or mitral incompetence is a disorder of the heart in which the mitral valve does not close properly when the heart.

Nelson text book of pediatrics, l3th ed. However, the decompensated phase is characterized by calcium overload within the cardiac myocytes.

This volume overload eventually causes mital drop in forward cardiac output 1,2. The loudness of the murmur does not correlate well with the severity of regurgitation.

This is known as the regurgitant orifice insufisiejsi, and correlates with the size of the defect in the mitral valve.

Either boys or girls with individual variation in endurance time. Surgery is curative of mitral valve regurgitation.

In particular, cardiac MRI CMR may be particularly useful for accurate measurements pertaining to the valve, regurgitant volume, and underlying etiology 1,7. The systolic presure tended to increase occurred at the age of y”ur.


Mitral insufficiency

Findings on clinical examination depend on the severity and duration of MI.

Saunders, ;5. The same phenomenon was reported by have shorter endurance time.

Cardiovascular disease heart I00—I52— The mitral valve apparatus comprises two valve leaflets, the mitral valve annuluswhich forms a ring around the valve leaflets, and the papillary muscleswhich tether the valve leaflets to the left ventricle and prevent them from prolapsing into the left atrium.


Philadel- Indones t; Acute MR as may occur due to the sudden rupture of a chorda tendinae or papillary muscle causes a sudden volume overload of both the left atrium and the left ventricle.

Skip to main content. It seems that the shorter endura- patients maintained sinus rhythm throughout the test. Circulation l; The chest X-ray in individuals with chronic MR is characterized by enlargement of the left atrium and the left ventricle.

This finding was in accordance with the finding of others that there was concordant with other reports. Thus, the causes of mitral regurgitation are protean and, as such, there is no single group of patients who are affected 1,2.
