A 25 year-old male with transposition of great arteries, ventricular septal defect and pulmoary stenosis successfully underwent Rastelli procedure with aortic homograft in 1969. After the procedure he grew up and became an engineer without any complaints. However, gradually his homograft degenerated with calcification and the pressure gradient between pulmonary artery and right ventricle increased to 77mmHg in systolic phase. Twelve years after the conduit repair, we operated upon and enlarged the ventricular septal defect, repaired the residual interventricular shunt, removed his homograft and, replaced it with the Hancock valved conduit from the right ventricular outfiow tract through cardiopulmonary bypass. On postoperative cardiac catheterization, the pressure gradient decreased, and the patient returned to his work.
