The mitral valve helps control blood flow through the heart. Mitral valve prolapse, also known as click-murmur syndrome or floppy valve syndrome, occurs when two valve flaps of the mitral valve do not close smoothly, but instead bulge upward into the heart’s left upper chamber (the left atrium) during a heartbeat.
Risk factors for mitral valve prolapse
Some factors that increase the risk of mitral valve prolapse include:
- Graves disease (a condition that affects the thyroid gland)
- Certain connective tissue disorders, such as Marfan syndrome
- Scoliosis and other skeletal problems
- Some types of muscular dystrophy
Symptoms of mitral valve prolapse
Symptoms of mitral valve prolapse may depend on the degree of the prolapse present, but keep in mind that you may not always show symptoms of mitral valve prolapse. The most common signs of this condition include:
- Palpitations or fast, irregular heartbeats
- Chest pain
- Cough
- Headaches
- Exercise intolerance
- Dizziness
