Abstract:
Mitral valve prolapse, diagnosed by auscultation of typical midsystolic clicks and late systolic murmurs or by echocardiographic demonstration of definite systolic protrusion of the mitral leaflets into the left atrium, is the commonest human abnormality of heart valves, affecting roughly 4 per cent of the population. The most important clinical features of mitral valve prolapse include palpitations and small but definite risks of infective endocarditis or significant mitral regurgitation in middle age, or later. Current evidence suggests that mitral prolapse is due to an inherited abnormality in connective tissue, which causes thoracic bony abnormalities and reduced body weight and blood pressure, in addition to the changes in the mitral valve.
Insights
Mitral valve prolapse (MVP) is the most common heart valve abnormality, affecting 4% of people. It is linked to inherited connective tissue issues and can cause palpitations and heart valve problems.
Area of Science:
- Cardiology
- Genetics
- Valvular Heart Disease
Background:
- Mitral valve prolapse (MVP) is the most frequent cardiac valve anomaly in humans.
- Affecting approximately 4% of the population, MVP is diagnosed via auscultation or echocardiography.
- Clinical manifestations include palpitations and risks of infective endocarditis or mitral regurgitation.
Purpose of the Study:
- To summarize the prevalence, clinical features, and underlying etiology of mitral valve prolapse.
- To highlight the association between MVP and inherited connective tissue disorders.
Main Methods:
- Review of existing clinical and research evidence on mitral valve prolapse.
- Diagnostic criteria including auscultation (midsystolic clicks, late systolic murmurs) and echocardiography were considered.
Main Results:
- Mitral valve prolapse is the most common heart valve abnormality.
- Associated conditions include thoracic bony abnormalities, reduced body weight, and low blood pressure.
- MVP carries risks for infective endocarditis and significant mitral regurgitation later in life.
Conclusions:
- Mitral valve prolapse is strongly associated with inherited abnormalities in connective tissue.
- These genetic factors contribute to a spectrum of physical characteristics beyond the mitral valve itself.
