Mitral valve prolapse: from syndrome to disease

Area of Science:

• Cardiology
• Psychiatry

Background:

• Mitral valve prolapse (MVP) encompasses diverse conditions affecting the mitral valve apparatus.
• While often benign, MVP can progress to mitral insufficiency or predispose to bacterial endocarditis.
• MVP is frequently associated with a syndrome including autonomic dysfunction and symptoms like chest pain, palpitations, and anxiety.

Purpose of the Study:

• To investigate the relationship between mitral valve prolapse and associated symptoms.
• To explore the potential link between MVP and anxiety disorders.
• To clarify the association between the severity of MVP and the degree of autonomic dysfunction or symptom severity.

Main Methods:

• Review of existing literature on mitral valve prolapse and associated conditions.
• Analysis of studies examining the co-occurrence of MVP and anxiety disorders.
• Correlation analysis between MVP severity, autonomic dysfunction, and symptom reporting.

Main Results:

• The risk of severe complications in MVP relates to patient sex, age, and prolapse severity.
• Little to no correlation exists between the extent of prolapse and the degree of autonomic dysfunction or symptom severity.
• Recent studies suggest that MVP and anxiety disorders are not directly linked, despite symptom overlap.

Conclusions:

• MVP is a heterogeneous condition with varying clinical implications.
• The association between MVP and anxiety disorders requires further clarification, with current evidence suggesting no direct link.
• Iatrogenic cardiac neurosis is a common finding in patients with MVP and anxiety disorders.
