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.

Mitral insufficiency

It is currently unclear what causes an individual to enter the decompensated phase of this disease. IVo out of 17 boys and in7 Secondary mitral insufficiency is due to the dilatation of the left ventricle that causes stretching of the mitral valve annulus and displacement of the papillary muscles.

They consisted of 17 boys obtained by measuring the interval between five R and 3l girls, Study subjects were selected from RHD waves, patients treated at the Outpatient Clinic, Cardiology Division, Department of Child Health, Cipto Ma- Heart rates, blood pressure, and the duration of exer- ngunkusumo Hospital, Jakarta, Indonesia from tion were recorded.

Individuals with acute MR are typically severely symptomatic and will have the signs and symptoms of acute decompensated congestive heart failure i.

Pulmonary edema associated with mitral regurgitation: In the artificial chordae approach, ePTFE expanded polytetrafluoroethylene, or Gore-Tex sutures are used to replace the broken or stretched chordae tendonae, bringing the natural tissue back into the physiological position, thus restoring the natural anatomy of the valve. Distribution of 3l girls studied based on age group and stage of endurance time rheumatic mitral regurgitation.

Also, it may detect a dilated left atrium and ventricle and decreased left ventricular function. motral

If the MR develops slowly over months to years or if the acute phase cannot be managed with medical therapy, the individual will enter the chronic compensated phase of the disease. In other projects Wikimedia Commons.

Mitral regurgitation Mitral valve insufficiency Mitral valve incompetence Mitral insufficiency Mitral incompetence. The quantification of MR usually employs imaging studies such as echocardiography or magnetic resonance angiography of the heart.

An individual may be in the compensated phase of MR for years, but will eventually develop left ventricular dysfunction, the hallmark for the chronic decompensated phase of mitral insufficiency. Unlike mitral regurgitation, mitral stenosis does not have left ventricular enlargement and usually has less striking enlargement of the left atrium 2. Atrial fibrillation may also be noted on the ECG in individuals with chronic mitral regurgitation.


The dilated left ventricle causes an increase in the wall stress of the cardiac chamber as well. In the left atrium, the volume overload causes enlargement of the left atrium, allowing the filling pressure in the left atrium to decrease.

The mitral valve apparatus comprises two valve leaflets, the mitral valve annuluswhich insufisiejsi 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.
