Mitral Valve Prolapse
Definition 1
A fairly common and often benign valvular heart disorder characterized by redundancy or hooding of mitral valve leaflets so that they prolapse into the left atrium, often causing mitral regurgitation. It is often a symptomless condition but may be marked by varied symptoms (e.g. chest pain, fatigue, dizziness, dyspnea, or palpitations) leading in some cases to endocarditis or ventricular tachycardia. (NCI Thesaurus)
Definition 2
Prolapse of the mitral valve, often with regurgitation, associated with myxomatous proliferation of the leaflets of the mitral valve. (Food and Drug Administration)
More information
Mitral valve prolapse (MVP) occurs when one of your heart's valves doesn't work properly. The flaps of the valve are "floppy" and don't close tightly. Most people who have the condition are born with it. It also tends to run in families.
Most of the time, MVP doesn't cause any problems. Rarely, blood can leak the wrong way through the floppy valve. This can cause
• Palpitations (feelings that your heart is skipping a beat, fluttering, or beating too hard or too fast)
• Shortness of breath
• Cough
• Fatigue, dizziness, or anxiety
• Migraine headaches
• Chest discomfort
Most people who have mitral valve prolapse (MVP) don't need treatment because they don't have symptoms and complications. If you need treatment for MVP, medicines can help relieve symptoms or prevent complications. Very few people will need surgery to repair or replace the mitral valve.
MVP puts you at risk for infective endocarditis, a kind of heart infection. To prevent it, doctors used to prescribe antibiotics before dental work or certain surgeries. Now, only people at high risk of endocarditis need the antibiotics. (NIH: National Heart, Lung, and Blood Institute)
