[Mitral valve prolapse. A prevalence study using bidimensional echocardiography in a young population]

Area of Science:

• Cardiology
• Medical Imaging

Context:

• Prevalence studies of mitral valve prolapse (MVP) are influenced by diagnostic methods and population selection.
• 2D-echocardiography is the current gold standard for diagnosing MVP, identifying both functional and anatomical types.
• Anatomical variations in MVP, such as leaflet thickening and ring dilation, are increasingly recognized as predictors of complications.

Purpose:

• To determine the prevalence of functional and anatomical mitral valve prolapse in a university student population.
• To assess the correlation between MVP types and clinical factors like body mass index, left ventricular function, and symptoms.
• To highlight the importance of distinguishing between functional and anatomical MVP for epidemiological research.

Summary:

• A study of 420 university students found functional mitral valve prolapse in 6.4% (27/420) and anatomical prolapse in 0.5% (2/420).
• No significant correlation was observed between MVP types and body mass index, left ventricular fractional shortening, or symptoms like dyspnea or palpitations.
• Auscultatory findings were absent in most cases of functional MVP, underscoring the diagnostic role of echocardiography.

Impact:

• The distinction between functional and anatomical mitral valve prolapse is valuable for standardizing results in future epidemiological studies.
• Further clinical follow-up is needed to ascertain the long-term clinical significance of differentiating between these two types of MVP.
• This research contributes to a better understanding of MVP prevalence and its clinical implications in young adults.
