Mitral Valve Prolapse (cont.)
Mitral Valve Prolapse Causes
For most people, the cause for mitral valve prolapse is unknown.
- Some people may inherit the condition, especially those associated with connective tissue disorders like Marfan's syndrome. Marfan's syndrome is an inherited disorder of connective tissue that causes abnormally long limbs, loose joints, and bulges (aneurysms) in the aorta, the main artery from the heart.
- Up to 40% of people have dysautonomia, an imbalance of the autonomic nervous system. This is the part of the nervous system that controls involuntary body functions such as breathing and the beating of the heart. This may lead to a large number of symptoms that seem serious to the person with the symptoms but are usually not serious (that is, they are not heart conditions).
