Mitral valve prolapse is a bulging of one or both leaflets in the mitral valve back into the left atrium. This is a very benign condition
and as such is often considered by cardiologists to be a “non-condition.” Mitral valve prolapse is fairly common, occurring
in about 10 to 15 out of 100 people.
Mitral valve prolapse is generally diagnosed as a heart murmur. Symptoms can include: headaches, dizziness, insomnia, shortness
of breath and palpitations.
If the mitral valve leaflets can seal shut, there is no effect on the individual. However, when these leaflets don’t shut
tight because there is too much tissue, blood can leak from the left ventricle into the left atrium. This is called mitral
valve insufficiency or mitral regurgitation. Depending on the severity, this may require treatment.
How is mitral valve prolapse treated?
Most patients require no treatment. In fact, many people go through life not knowing they have a mild form of the condition
and not experiencing symptoms.
Occasionally, children with mitral valve prolapse experience chest pain and irregular heartbeat. If treatment is needed, the
symptoms of mitral valve prolapse can often be controlled with drugs. Surgery is rarely necessary, though for severe cases
valve repair or valve replacement may be considered. Usually, physical activity is not restricted. Regular physical examinations
will be needed.
What is the long-term outlook for children with mitral valve prolapse?
The outlook for children with mitral valve prolapse is very good.
