Mitral valve prolapse is defined as a non-life-threatening structural defect in the heart, causing the valve to improperly close, that usually causes no symptoms. It is a common genetic condition. MVP usually runs in families: If you have relatives with MVP, then there’s a good chance you probably do too.
Symptomatic mitral valve prolapse is called mitral valve prolapse syndrome. Common symptoms are awareness of heartbeat, heart murmur, arrhythmia, chest pain, palpitations, fainting, fatigue, low blood pressure, low exercise tolerance, dizziness, anxiety, panic attacks, temperature sensitivity, insomnia, IBS, “lump-in-the-throat” feeling/difficulty swallowing, migraines, allergies, muscle spasms, medication sensitivity, and shortness of breath.
There is a higher incidence of MVP among those who have Grave’s disease, hypomastia, Duchenne muscular dystrophy, myotic dystrophy, sickle cell disease, atrial septic defect, Marfan’s syndrome, and rheumatic heart disease. There also seems to be a higher incidence among women.
Quite often there are similarities in body types among those who have MVP. Many people (but definitely not all) have lax joints, are tall and thin, and have long arms and fingers. Twenty-five percent of MVP patients also have a high arched palate, scoliosis, funnel chest, or straight back.
