Which are the symptoms of Mitral Valve Prolapse Syndrome?

Mitral Valve Prolapse Syndrome (MVPS) typically presents with symptoms such as palpitations, chest pain, and fatigue, though many individuals remain entirely asymptomatic. While the structural prolapse of the mitral valve is often benign, symptoms can fluctuate significantly based on autonomic nervous system involvement and the degree of associated mitral regurgitation.

What are the most common symptoms of Mitral Valve Prolapse Syndrome?

The clinical presentation of Mitral Valve Prolapse Syndrome is highly variable. While many patients are diagnosed incidentally during a routine physical exam, those who are symptomatic often report a cluster of sensations often linked to dysautonomia. Common symptoms include:

• Palpitations or a sensation of a "skipped beat"


• Atypical chest pain (often sharp, localized, and unrelated to exertion)


• Chronic fatigue and exercise intolerance


• Episodes of lightheadedness or dizziness


• Shortness of breath, particularly during physical activity


• Anxiety or panic-like symptoms

How does symptom severity vary between patients?

The severity of Mitral Valve Prolapse Syndrome does not always correlate with the anatomical degree of valve prolapse. Some individuals with minimal valve displacement experience profound palpitations and fatigue, while others with significant prolapse remain asymptomatic. Factors such as the presence of mitral regurgitation (the backward flow of blood) and individual sensitivity to autonomic fluctuations influence how Mitral Valve Prolapse Syndrome impacts daily life.

When should I seek immediate medical attention?

While Mitral Valve Prolapse Syndrome is generally not life-threatening, patients should seek emergency care if they experience severe, persistent chest pressure, fainting (syncope), sudden onset of severe shortness of breath, or an irregular heartbeat that does not resolve. These signs may indicate complications such as significant regurgitation or arrhythmias that require urgent evaluation by a cardiologist.

How do symptoms evolve over time in Mitral Valve Prolapse Syndrome?

For most patients, Mitral Valve Prolapse Syndrome remains stable throughout their lifetime. However, in a minority of cases, the valve tissue may gradually thicken or the chordae tendineae (the "strings" supporting the valve) may stretch, potentially increasing the severity of mitral regurgitation. Regular echocardiographic monitoring is recommended to track these structural changes and manage symptoms effectively.
