Abstract
Hemodynamic studies of cardiovascular disease were made on 318 patients ranging in age from 2 months to 87 years, and the diagnostic usefulness of the scinatillation camera with radioistope was evaluated forty five of the patients (aged 5 to 24), considered to be normal, were used for computing normal values. Equipment consisted of a Pho/Gamma III type scintillation camera, a 35 mm time lapse camera and a 1600 word memory sytem. Radio-pharmaceuticals used for the study were sup(113m)In and sup(99m)-Tc. Administration of the isotope was by arm injection, allowing it to pass through the heart chamber and major blood vessels as a large bolus of radioactivity. For children 3 years and under, a pinhole collimater was employed to magnify cardiac images and enhance resolution. In septal defects, right left shunting was easier to demonstrate than was left right. Atrial and/or ventricular changes in valvular disease were readily observed on the radio-angiogram and corresponded to the degree of damage. Increased blood pooling was also demonstrable. Hemodynamic changes in each chamber were established by the drafting of an isotope dilution curve, and the C/sub 2/ C, ratio, expressed as a percentage, was obtained from the curve. This safe, low risk radionuclide evaluation
