What is the prolapse of the mitral valve?
When cardiac contractions, mitral valves, located between the left atrial and the chamber, open to allow the blood to pass into the left ventricle. In the prolapse of the mitral valve, the mining valve has the leaflets that open, and the chains or chordae that support the valve. A small amount of blood leaks, called regurgitation , as a result of the leaflets do not meet perfectly when they close.
Although the defect once considered, a certain degree of malformation of the mitral valve is now considered a normal variation. In approximately 95% of cases, the benign prolapse of the mitral valve never requires surgery, although doctors can hear a significant sturdy with a stethoscope. Important is the diagnosis of prolapse of the mitral valve, although it is mild. Even those who have a very mild form should probably take antibiotics before dental tests and procedures of bacterial endocarditis.
prolape Mitral valve does not pose problems for infants unless there is seriousOr butt with other congenital heart defects, but tends to deteriorate with age. Symptoms of this condition may be recognized over adolescent years or cannot be recorded until a person is in a good or third decade. Symptoms do not necessarily indicate the severity of the mitral valve prolapse. In some cases, a slight prolapse leads to symptoms, but does not require treatment. In other situations, prolapse may be significant, but does not have many symptoms.
When the treatment of mitral valve prolapse is required, several options are considered, the first are medicines to improve the function of the heart rhythm and the control heart rhythm. If there is a blockage in the valve, a minimally invasive balloon valvuloplastics may try to open the valve passage and prevent blood from backing up in the left atrium. Ballo -balloon is not generally successful, as the mitral valve prolapse tends to repeat.
If possible, the cardiotorac surgeon will try to repair the valve. If necessary, it can separate leaflets and also shorten the chordae to create a more efficient valve. Often, however, surgeons decide to completely replace the valve. The new valve can be either pig or beef valve or often a mechanical valve.
pig and bovine valves are not as viable as mechanical valves. They have the advantage that they only require blood thinners several months after the operation. Mechanical valves require blood thinners throughout their lives such as warfarin. This can be particularly difficult for small children, because the level of warfarin must be consistently monitored.
Mitral valve prolapse was associated with several causes. The rheumatic fever can damage the mitral valves and the surrounding heart tissue. Mitral valve prolapse may be a congenital condition or may cause bacterial endocarditis. There are evidence that suggests that the innate prolapse of the mitral valve may be genetic, thereforethat it tends to be present with more than one family member. If you have a family history of mitral valve prolapse, inform your doctor as the problem can be easily diagnosed through the echocardiogram.
