    Abstract:
    OBJECTIVE: To compare the effect of right anterolateral minithoractomy and median sternotomy for atrial septal defect closure. METHODS: In this study, 82 patients, whose age ranged from 4 to 46 years with a mean of 15.7+/-8.6 years, underwent surgical repair of the atrial septal defects on the beating heart through right anterolateral minithoractomy. Ten of these cases were complicated by moderate to severe pulmonary hypertension, and 3 by partial anomalous pulmonary venous connection. Another 67 patients with an age range of 3 to 49 years (mean 17.0+/-12.5 years) underwent surgical repair of the atrial septal defects through full-length median sternotomy with the heart beat arrested, and complication of moderate to severe pulmonary hypertension was identified in 11 cases and partial anomalous venous connection in 5. Comparisons were performed between the 2 groups in terms of the length of skin incision, cardiopulmonary bypass (CPB) time, postoperative mechanical ventilation time, intensive care unit stay, postoperative hospital stay, and the volume of postoperative drainage. RESULTS: There was no operative mortality in either of the 2 groups. In the former group, the CPB time (35.2+/-14.1 min), postoperative mechanical ventilation time (6.5+/-2.5 h), postoperative drainage volume (237.6+/-172.5 ml), postoperative hospital stay (7.4+/-1.2 d) and skin incision length (6.5+/-0.9 cm) were all significantly less than those of the latter group of patients, whose CPB time was 42.7+/-11.8 min, postoperative mechanical ventilation time 7.9+/-3.8 h, postoperative drainage volume 304.3+/-192.4 ml, postoperative hospital stay 9.0+/-2.9 d and skin incision length 15.9+/-1.7 cm (P < 0.01). The intensive care unit stay did not differ significantly between the 2 groups (35.1+/-16.2 h vs 32.3+/-24.1 h, P > 0.05). CONCLUSION: A right anterolateral minithoracotomy for repairs of atrial septal defects is a safe, effective and simple technique to ensure minimal surgical invasion with shorter postoperative hospital stay. Minithoracotomy can be performed to replace median sternotomy in the correction of atrial septal defects, including those complicated by partial anomalous pulmonary venous connection.
