Barlow syndrome; Floppy mitral valve; Myxomatous mitral valve; Billowing mitral valve; Systolic click-murmur syndrome; Prolapsing mitral leaflet syndrome
Many patients with mitral valve prolapse do not have symptoms. The group of symptoms found in patients with mitral valve prolapse is called "mitral valve prolapse syndrome" and includes:
- Sensation of feeling the heart beat (
Chest pain(not caused by coronary artery diseaseor a heart attack)
Difficulty breathingafter activity Fatigue Cough
Shortness of breathwhen lying flat ( orthopnea)
Note: There may be no symptoms, or symptoms may develop slowly.
Signs and tests
The doctor will perform a physical exam and use a stethoscope to listen to your heart and lungs. The doctor may feel a thrill (vibration) over the heart, and hear a heart murmur ("midsystolic click"). The murmur gets louder when you stand up.
The following tests may be used to diagnose mitral valve prolapse or a leaky mitral valve:
- Color-flow Doppler examination
- Cardiac catheterization
ECG(may show arrhythmiassuch as atrial fibrillation) Chest MRI CT scan of the chest
