[Diastolic mitral regurgitation (author's transl)].
An analysis of left ventricular angiograms not seldom revealed a diastolic mitral regurgitation. There was neither a correlation between the diastolic mitral regurgitation and the anatomic situation in the coronary system nor with the left ventricular function. The diastolic regurgitation always occurred in a postextrasystolic pause at the end of the diastole. While the systolic mitral regurgitation produces a jet appearance of contrast material, the diastolic mitral regurgitation is seen as a floating of contrast material into the atrium. The cause of the diastolic mitral regurgitation appears to be an incremented left ventricular filling subsequent to repeated and incoordinately-occurring extrasystoles with diminished systolic ejection which leads to reversal of the pressure gradient between the left atrium and left ventricle and permits regurgitation over the incompletely closed valve.
