Symptoms of Mitral Valve Prolapse

In mild cases, symptoms of mitral valve prolapse are often not present. People who do have signs and symptoms may experience chest pain, palpitations, lightheadedness, or fainting. More severe complications and symptoms of the condition, including sudden death, may occur in extreme cases.

Signs and Symptoms of Mitral Valve Prolapse: An Overview

People with mitral valve prolapse usually don't have any symptoms, although they sometimes will occur. Since the condition is so common, it is difficult to say whether these symptoms are due to the prolapse or something else.
 
If someone does have mitral valve prolapse symptoms, they might include:
 
  • Chest pain
  • Heart palpitations
  • Lightheadedness
  • Fainting.
     

Severe Mitral Valve Prolapse Symptoms

Complications can result from mitral valve prolapse, but they are rare, occurring in less than 1 percent of people with this condition. Possible complications include:
 
  • Stroke or TIA (also known as a "mini-stroke")
  • Arrhythmia
  • Mitral regurgitation (blood going back up into the left atrium)
  • Sudden death.
     
People with mitral valve prolapse who are under the age of 45 and do not have mitral regurgitation are at low risk for any complications from their condition.
