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.

Objective Evaluate the outcome of total anomalous pulmonary venous connection (TAPVC) repair in newborn,controlling for anatomic subtypes and surgical technique.Methods Between 1999 and 2011,68 patients (median age 16 days) underwent repair for supracardiac (21),cardiac ( 8 ),infracardiac ( 36 ) or mixed ( 3 ) TAPVC.All patients were emergencies,due to obstructed drainage.Supracardiac and infracardiac TAPVC repair included the side-to-side anastomosis between the pulmonary venous (PV) confluence and the left atrium.Coronary sinus unroofing was preferred for cardiac TAPVC repair.Results Early mortality was 2.9% (2/68).The echo showed no obstruction in the pulmonary vein anastomosis and flow rate was 1.1 m/s ~ 1.42 m/s in the follow-up of 3 years.Side-to-side anastomosis provides excellent results for TAPVC repair while left atrial enlargement procedures appear to be associated with higher risk of late arrhythmias.Although early and aggressive reintervention for recurrent PV obstruction is mandatory,intrinsic PV stenosis remains a predictor of adverse outcome.The incidence of pulmonary vena is gradually reduced to 6% ~ 11%.This often occurred in the infracardiac or mixed TAPVC.Conclusion The nicety of preoperative diagnose,the improvement of protection of heart function,using of pulmonary vena tissue for anastomose and avoiding of distortion of pulmonary venues and delayed closure of stemum can reduce the mortality.The preoperative degree of pulmonary veno obstruction and the time of emergency operation and the infracardiac or mixed TAPVC can affect prognosis.Along with the surgical technique,the mortality of TAPVC is gradually reduced and the result is amazing,but it is important to attach importance to the patient with re-stenosis of pulmonary veno,the time and method for reoperation.
