What is Mitral Valve Prolapse Syndrome

Mitral Valve Prolapse Syndrome (MVPS) is a condition where one or both leaflets of the mitral valve in the heart bulge backward into the left atrium during contraction, sometimes causing blood to leak backward (regurgitation). While often benign, the syndrome can present with a constellation of symptoms including palpitations, chest pain, and anxiety, which are thought to be linked to autonomic nervous system dysregulation.

What causes Mitral Valve Prolapse Syndrome?

The primary mechanism of Mitral Valve Prolapse Syndrome involves structural changes in the valve tissue, often classified as myxomatous degeneration, where the connective tissue of the valve becomes thickened and redundant. In many cases, this is a primary, idiopathic condition, though it can also be associated with connective tissue disorders like Marfan syndrome or Ehlers-Danlos syndrome. The "syndrome" aspect specifically refers to the collection of systemic symptoms that occur alongside the valve abnormality, which may result from an imbalance in the autonomic nervous system.

Who is typically affected by the syndrome?

Mitral Valve Prolapse Syndrome is one of the most common valvular abnormalities, estimated to affect approximately 2% to 3% of the general population. While it can occur at any age, it is frequently diagnosed in early adulthood. Current clinical data suggests:

• It is more commonly diagnosed in women than in men.


• Onset of symptoms often occurs between the ages of 20 and 40.


• A family history of Mitral Valve Prolapse Syndrome is frequently reported, suggesting a genetic predisposition in many cases.

How is Mitral Valve Prolapse Syndrome different from other heart conditions?

Unlike severe structural heart disease, many people with Mitral Valve Prolapse Syndrome lead healthy, active lives without needing intervention. It is distinct from rheumatic heart disease or ischemic heart disease because the primary issue is the physical "floppiness" of the valve leaflets rather than damage from infection or restricted blood flow to the heart muscle itself. At DiseaseMaps.org, 23 people with Mitral Valve Prolapse Syndrome have shared their experiences, highlighting the importance of managing both the physical valve function and the quality-of-life impact of associated symptoms.

Next steps

• Consult a cardiologist for an echocardiogram to assess the severity of the valve prolapse.


• Keep a symptom diary to track palpitations or chest pain to discuss during your clinical visits.


• Connect with the community at DiseaseMaps.org to share experiences with others living with Mitral Valve Prolapse Syndrome.


• Discuss with your physician whether lifestyle modifications, such as hydration or electrolyte management, may help manage autonomic symptoms.
