title: Prevalence of mitral valve prolapse in hypertension.
abstract: Mitral valve prolapse was found in one of 133 patients with hypertension (0.75 percent) studied by two-dimensional echocardiography. This rarity may be related to the presence of hypertrophied papillary muscles that probably pull the chordae tendinae and mitral valve leaflets away from the left atrium in systole, thus preventing their eversion and prolapse.
