title: [Proceedings: Quantification of mitral valve insufficiency by means of videodensitometric measurement of the amount of contrast media in angiocardiography].
abstract: A new indicator quantity principle is presented which permits estimation of the regurgitant fraction in mitral incompetence from left heart angiocardiography by videodensitometric measurement of contrast medium content in the left heart chambers. In 90 experiments on dogs, a linear correlation of r = 0.89 was established between simultaneous determinations of mitral regurgitation by videodensitometry and electromagnetic flow measurement. Since only 1 catheter is needed for the injection of contrast medium and concomitant aortic incompetence can be computed from the same videodensitograms, this method is considered to be of special interest in clinical heart catheterization.
