Recently, direct atriopulmonary anastomosis was performed in 2 patients without using pericardium or prosthetic material. Case 1 A 13-year-old male patient whose diagnosis was tricuspid atresia [type lb] received direct atriopulmonary anastomosis successfully with good clinical and hemodynamic results. Nine months after operation, he has an increased exercise tolerance. Case 2 A 4-year-old female patient whose diagnosis was DORV with pulmonary atresia in A-V discordance had a formidable surgical challenge. A large-diameter direct atriopulmonary anastomosis was performed after the closure of the right atrioventricular valve. Her postoperative course has been even in 20th postoperative day.
