title: Rest and exercise radionuclide ventriculography in the ambulatory monitoring of patients with valvular heart disease.
abstract: Radionuclide angiography serves as a valuable adjunct in the noninvasive evaluation and monitoring of patients with valvular heart disease. Although estimations of regurgitant fractions and the differences between left and right ventricular stroke volumes can be made, the limitations of the techniques do not enable adequate quantitation of the severity of valvular insufficiency to warrant routine use in ambulatory management. The importance of radionuclide ventriculography, however, lies in its ability to examine global ventricular function both at rest and with exercise, thus enabling assessment of the functional reserve of the left and right ventricles. Such data are of considerable value in determining the need for invasive evaluation and the timing of valve replacement in patients with valvular heart disease.
