[Cineangiocardiographic evaluation of mitral valve lesions. Validity of the method according to 100 angio-surgical correlations].

In order to assess their validity, the findings on left bidirectional cineventriculography have been compared with the operative findings in 100 patients with mitral valve disease. This method of investigation has been shown to be a reliable one for the precise and complete evaluation of mitral valve lesions. The information which it provides about the morphology and kinetics of the valve, the site of any calcification, the state of the suspensory apparatus, and the degree and cause of any mitral incompetence often has a decisive influence on the indications for surgery and the choice of operation.
