In pulmonary atresia with a ventricular septal defect and similar congenital heart disorders the pulmonary blood supply is often multifocal. The relative distribution of pulmonary perfusion from individual sources is usually demonstrated by selective angiography. A new technique using a selective injection of radionuclide labelled human albumin microspheres was performed in four patients with a complex pulmonary blood supply. In these cases the physiological distribution of each of the multiple sources of pulmonary perfusion was demonstrated. This is a useful additional technique in the assessment of such patients.

Baker et al. (1984) conducted a case report in Pulmonary atresia with a ventricular septal defect and complex multifocal pulmonary blood supply (n=4). Selective injection of radionuclide labelled human albumin microspheres was evaluated on Demonstration of the physiological distribution of each of the multiple sources of pulmonary perfusion. Selective injection of radionuclide labelled human albumin microspheres successfully demonstrated the physiological distribution of multiple sources of pulmonary perfusion in four patients.
