Mitral valve prolapse (MVP) is a common heart condition, and in most persons does not cause symptoms. It results from a fluttering of the valve on the left side of the heart, between the small chamber (atrium) and the large chamber that pumps blood to the body (ventricle).
Some patients can experience chest pain, rapid heartbeat, and anxiety from MVP and are treated with medication. In some severe cases, valvular replacement may be needed.
The relationship between headache and mitral valve prolapse is uncertain, although there have been reports of MVP being more common in migraine sufferers.
