Criteria for adverse prognosis for mitral valve prolapse.

On the basis of a survey of 151 patients, diagnostic criteria for an unfavorable prognosis of mitral valve prolapse were revealed according to echocardiography. Transthoracic and transesophageal echocardiography, daily Holter ECG monitoring were performed. Repeated echocardiography was performed in 12-18 months. Statistical analysis of the material allowed us to identify criteria for poor prognosis of mitral valve prolapse according to echocardiography: severe mitral regurgitation, mitral valve leaflet thickness in diastole 6 mm or more, dilatation of the left ventricular cavity, dilatation of the left atrial cavity, dilatation of the mitral ring.
