title: Tricuspid insufficiency detected by equilibrium gated radionuclide study.
abstract: The results of a gated radionuclide cardiac study are reported in a patient with biventricular failure and tricuspid insufficiency demonstrated by clinical evaluation, M-mode and 2-D sector echocardiography, and cardia catheterization. The processed gated radionuclide cardiac study showed a left ventricular/right ventricular stroke volume ratio of 0.5; expansion of the hepatic blood pool demonstrated by hepatic time activity curve and calculation of an "'expansion fraction"; and synchronous changes of count rate of the atrial and hepatic regions detected by phase analysis (similar phase shifts).
