Summary Pre‐ and postoperative hemodynamic and electrocardiographic studies were carried out in 24 children with patent ductus arteriosus and pulmonary hypertension. The age of the patients ranged from 10 months to 14 years. All patients were catheterized before and a t least once after the operation. I n all cases a left to right shunt was present. Prior to operation the pulmonary arterial pressure was 50 mm Hg or more. The follow‐up time ranged from 6 months to 4½ years. Clinical improvement and a decrease of the pulmonary arterial pressure occurred in all cases after operation. The postoperative systolic pressure in pulmonary artery was 40 mm Hg or less in 14 children; all these children had had large shunts and 10 of them were less than 7 years of age. In the 4 cases, in which more than one postoperative catheterization was performed, no significant hemodynamic changes were seen after the first postoperative year. Before operation 18 patients had electrocardiographic signs of combined ventricular hypertrophy. Following surgery the tracings became normal in most cases. Isolated right ventricular hypertrophy in the preoperative or persisting right ventricular hypertrophy in the postoperative tracings were unfavourable signs and occurred in cases, in which only a small lowering of the pulmonary arterial pressure occurred.
