Angiographic volume parameters were evaluated in 24 patients with secundum atrial septal defect and 16 patients with patent ductus arteriosus. In both atrial septal defect and patent ductus arteriosus, involved ventricles had increased end-diastolic volume, increased stroke volume and normal ejection fraction, and the contralateral ventricles had normal end-diastolic volume, stroke volume and ejection fraction. The involved atrial volumes were increased in both diseases. Left atrial maximal volume was larger than normal in atrial septal defect. Right atrial maximal volume was normal in patent ductus arteriosus. The ratios of involved to contralateral ventricular stroke volume were well related to the pulmonary to systemic flow ratio by the Fick method in patent ductus arteriosus, but not so well in atrial septal defect. These results indicate that the regression equation in right ventricular volume calculation should be reevaluated in right ventricular volume overload and that left heart volume provides a reliable indicator of pulmonary flow in the patients without atrial septal defect and valvular desease.
