title: [Screening for a frequent cardiac disorder: mitral valve prolapse].
abstract: Mitral valve prolapse (MVP) screening using bidimensional echocardiography was performed on 171 healthy subjects from Lorraine of both sexes, aged 20 to 60 years. Six men and seven women presented this valvular disease. In the Lorraine population, the estimated prevalence of MVP was 7.6% (95% confidence interval: 3.6-11.6%). In this study, only seven cases of MVP had a cardiac auscultation suggestive of MVP. As compared with echocardiography, clinical screening of MVP had a low validity (sensibility 54%, specificity 69%) and a poor positive predictive value (12.5%). Because MVP has severe complications, and because clinical screening has a low performance, a strategy of screening with bidimensional echocardiography could be interesting.
