Objective To report the experience of surgical treatment of 4 patients with complete transposition of great areteries (TGA). Methods 4 cases received arterial switch operation and senning operation from November 2004 to January 2008, including 1 case of TGA without VSD(TGA - IVS), 3 TGA with VSD (TGA -VSD), 2 TGA with Mild pulmonary valve stenosis. Results There no death during the operation or postoperation. Patients were followed up from 5 months to 3years. All the patients got better ,grew faster and cyanosis relieved apparently. 2 patients had mild to moderate mitral regurgitation preoperatively. I patient had mild mitral regurgitation post-operatively and 1 patient had no mitral regurgitation. There was no aortic stenosis or pulmonary valve stenosis after operation. I patient assis-ted respiration for 62 days after operation because of old age. All the patients recovered smoothly after operation. Conclusion Using arte-rial switch operation and senning operation to correct complete transposition of great artery could get satisfying operative results, and the ar-terial switch operation will also get good effect in older children with better left ventricular development.
