A 7-year-old girl with type I truncus arteriosus successfully underwent a Rastelli-type operation. Pulmonary artery banding had been performed for severe congestive heart failure refractory to medical treatment at 3 months of age. Two years later, she underwent a right modified Blalock-Taussig shunt for hypoxemia associated with decreasing pulmonary blood flow resulting from her continued growth. A longer than normal distance between the right ventricle and the pulmonary arteries and dilation of the common trunk prevented alternative reconstruction of the pulmonary trunk using autologous tissue. We reported our experience of a radical operation for type I truncus arteriosus and discussed the timing of definitive repair after palliation for this congenital cardiac anomaly.
