Human heart has four valves namely mitral valve, aortic valve, pulmonary valve and tricuspid valve. The mitral valve is also known as bicuspid valve or left antriventricular valve. It is seen as a dual flap valve between the left atrium and left ventricle.
The mitral valve has got two flaps of tissues known by the name leaflets. It opens when the blood flows from left atrium to the left ventricle. Each time when the blood flows, the flaps close so as to prevent the blood from flowing backwards.
Mitral valve regurgitation is one of the most commonly seen heart valve disorder. Here you can read the details.
In patients with mitral valve regurgitation, the mitral valve does not close tightly. Therefore some quantity of the blood from the left ventricle will flow backward into the left atrium, instead of going into the aorta, with each heartbeat. The leakage will increase the pressure and volume of the blood in the area. The heart will become inefficient in pumping blood resulting in shortness of breath and dizziness. Mitral valve regurgitation is also called mitral insufficiency or mitral incompetence.
There are two types of mitral valve regurgitation. They are:
What causes mitral valve regurgitation?
Here are the probable reasons of the mitral regurgitation:
The symptoms will develop gradually, unless it occurs suddenly. However, the symptoms will suddenly show up if the regurgitation occurs after a heart attack.
Treatment for mitral regurgitation
If it is mild regurgitation, treatment is not necessary. For patients with high BP, medication is suggested to lower it. Doctors may recommend anticoagulation medicine as well. Mitral valve replacement or repair surgery is suggested for patients if it is in later stages.
Mitral valve repair: The cardiac surgeon will repair the valve by reconnecting the valve leaflets or by removing the extra tissues in order to tight closely.
Mitral valve replacement: The cardiac surgeon will replace the mitral valve with mechanical or biological valve.
