Eight children with congenital pulmonary atresia with ventricular septal defect were investigated. The anatomy of pulmonary blood supply was established by aortography and multiple selective injections of contrast medium into aortopulmonary anastomoses or pulmonary arteries. All patients were shown to have central pulmonary arteries (derived from the embryological sixth aortic arches). In 4 (group I) the central pulmonary arteries had been supplied via a persistent ductus arteriosus alone (3 subsequently had surgical aortopulmonary shunts). In 3 (group 2), the central pulmonary arteries were supplied via major aortopulmonary collateral arteries alone, and in I patient (group 3) pulmonary blood supply was derived both from collateral arteries and a persistent leftfifth aortic arch. Systolic pressure gradients of 28 to 8I mmHg were demonstrated in each patient at the pulmonary artery end of the aortopulmonary anastomosis, whatever its nature. All patients in group I, and I patient in group 2 had unifocalpulmonary blood supply, i.e. the sixth aortic arch asasto,nosed with, and provided a single focusfor, all systemic sources of pulmonary blood supply. Pulmonary resistance relative to sixth aortic arch pressure rangedfrom 1`4 to 6.4 units M2. The remaining patients had multifocal pulmonary blood supply, i.e. one or more aortopulmonary collateral arteries provided pulmonary blood supply independent of the sixth aortic arch. In this group the minimum pulmonary resistance relative to the sixth aortic arch rangedfrom 3-9 to I2-i5 units M2. The latterfigure suggested the presence of severe pulmonary vascular disease. Thus
