Key result

Mitral valve prolapse affects ~2% to 3% of the population with marked clinical and genetic heterogeneity.

Why the study?

MVP is a common disorder associated with significant clinical complications, yet it remains not fully understood with undefined causative genes for the more common autosomal-dominant form.

Key Points

To synthesize current evidence on the diagnostic criteria, epidemiology, genetic mechanisms, pathophysiology, and clinical management of mitral valve prolapse.
Reviewed observational and community-based cohort studies evaluating the prevalence, clinical manifestations, and long-term prognosis of mitral valve prolapse.
Assessed two-dimensional and three-dimensional echocardiographic diagnostic standards based on saddle-shaped mitral annular geometry and leaflet displacement.
Mitral valve prolapse afflicts 2% to 3% of the general population, affecting ≈7.8 million individuals in the United States and >176 million people worldwide.
Diagnostic criteria require single or bi-leaflet displacement of at least 2 mm beyond the long-axis annular plane, classified as classic when leaflet thickening exceeds 5 mm.
Women present with milder clinical features and less mitral regurgitation than men but undergo mitral surgery less frequently and later, exhibiting excess long-term mortality.

PICO

Population

A comprehensive review of the epidemiology, pathophysiology, genetics, and clinical prognosis of mitral valve prolapse.

Exposure / Comparator

Mitral valve prolapse

This review provides a comprehensive overview of the epidemiology, genetics, and pathophysiology of mitral valve prolapse, highlighting its clinical heterogeneity and potential future therapeutic targets.

Discussion

No takes yet. Share an insight, caveat, or question.

Implication

MVP heterogeneity warrants clinical awareness; leaves open complete genetic mechanisms and targeted therapies for common forms.

Cite This Study

Delling et al. (2014) conducted a review in Mitral valve prolapse. Mitral valve prolapse was evaluated. Mitral valve prolapse is a common disorder affecting 2% to 3% of the general population, characterized by myxomatous degeneration and associated with significant clinical heterogeneity and genetic loci.
