Functional assessment of the total artificial heart by blood-pool radionuclide angiography.
Blood-pool radionuclide angiography was used to image a patient with a Jarvik 7-(70) total artificial heart. Excellent delineation of the chambers was achieved, allowing assessment of the total artificial heart pumping function. Estimation of the left ventricular volumes, cardiac output, and filling rates by radionuclide angiography corresponded closely with those simultaneously obtained from the total artificial heart driving lines. Radionuclide angiography affords the unique possibility to assess the function of the artificial heart noninvasively.
