title: [Videodensitometric determination of relative blood regurgitation volume in aortic valve insufficiency].
abstract: A simple video densitometric method based on the indicator distribution principle in the region of interest permits the determination of the relative amount of regurgitation between the ascending aorta and the left ventricle in cases of aortic valve insufficiency. The experimental basis and early clinical measurements are described and are compared with the more conventional methods of cine angiography and radionuclide ventriculography.
