Abstract：

Objective To evaluate the short term outcome of surgical treatment of supracardiac total anomalous pulmonary venous connection (TAPVC) via superior approach in neonates and infants. Methods From June 2006 to June 2009, 26 patients with supracardiac TAPVC underwent surgical repair through superior approach. There were 17 males and 9 females. Their ages ranged from 18 days to 8 months old (mean, 4. 2 ± 2. 8 years). The weight ranged from 3.4 to 8. 1 kg (mean, 5. 8 ± 2. 1 kg). Before surgery, all patients had apnea and cyanosis at resting state, and their resting SpO2 ranged from 65% to 85%. The heart/chest ratio calculated on X-ray film was from 0. 62 to 0. 77. Electrocardiograph (ECG) of the patients showed sinus rhythm, right atrium enlargement and right ventricle hypertrophy. Echocardiography revealed moderate to severe pulmonary hypertension and various degree of tricuspid reflux Under general anesthesia and cardiopulmonary bypass, direct anastomosis between the top of the left atrium and the common pulmonary venous trunk were performed via superior approach. Results The cardiopulmonary bypass time was 68. 7 ± 15. 3 min and the aortic cross-clamping time was 47. 6 ± 14. 7 min. The patients were followed up for 5 months to 3 years (mean, 18 months). No death after surgery was noted. Five patients had atrial arrhythmia (19. 1%)in the early postoperative stage. One patient had mild anastomotic stenosis, Two neonates had delayed sternum closure. Two patients had diaphragm paralysis, one of which underwent diaphragm placation.All of the patients except 2 had satisfactory cardiac function. Conclusions Correction of supracardiac total anomalous pulmonary venous connection via superior approach is safe and effective in neonates and infants.
