[Results of radionuclide ventriculography in normal children and adolescents]

In order to assess the range of normal values of radionuclide ventriculography the authors selected retrospectively 53 normal children and adolescents. All were examined by radionuclide angiocardiography on account of clinical and echocardiographical suspicion of congenital heart disease with a left-to-right shunt; a significant shunt was, however, excluded. In all patients after equilibration of the radiotracer ventricular function was examined by radionuclide ventriculography. The authors evaluated the usual volume, time and rate characteristics. The normal range was defined as the mean +/- 2 standard deviations which is for the ejection fraction of the left ventricle 47 to 72% and for the ejection fraction of the right ventricle 31 to 56%. The other results are discussed in detail in the text.
