Successful correction of truncal valve regurgitation and conduit obstruction after previous Rastelli operation for truncus arteriosus (type I)

A 9-year-old boy had a successful surgical correction of truncal valve regurgitation and obstruction of extracardiac conduit which ensued previous Rastelli operation. He underwent Rastelli operation at the age of 10 months with the diagnosis of truncus arteriosus (Collet & Edwards Type I). At the age of 8 years, he was admitted because of slow weight gain and cardiomegaly (CTR 64%). Cardiac catheterization showed elevated RV pressure, increased pressure gradient across the conduit and severe truncal valve regurgitation. The extracardiac conduit was replaced with a 22 mm Hancock valved conduit and the truncal valve with 23 mm St. Jude Medical aortic valve. Postoperative catheterization revealed a normal RV pressure, only slight pressure gradient across the conduit and no truncal valve regurgitation. He is doing quite well 2 years after the operation.
