Surgical repair of type IIIpulmonary atresia with ventricular septal defect

Abstract

Objective To evaluate the outcomes of surgical repair of typeⅢ pulmonary atresia with ventricular septal defect(PA/VSD). Methods Retrospectively analyzed the clinical data of 98 patients with type Ⅲ PA/VSD who underwent surgical repair in the Department of Cardiovascular Surgery, Guangdong Cardiovascular Institute from September 2005 to December 2014. There were 54 males and 44 females at the mean age of(4.2±4.8) years and the mean weight of(13.2±10.0) kg. There were 67 patients in palliative repair group and 31 patients in radical repair group. There were 85 patients underwent on-pump operation including 9 beating heart cases. Results The mean bypass time was(121.2±49.4)min, the mean aorta cross-clamping time was(75.4±31.8) min.The overall postoperative mortality was 6.1%(6/98). For the survival patients, the mean ventilation time was(106.7±184.3) h, the mean ICU stay was(8.9±10.9) days and the mean hospital stay was(33.4±17.0)days. During follow-up period, 28 patients were underwent re-operation, the postoperative mortality was 7.1%(2/28). There were no differences in postoperative status between two groups. Conclusion The outcomes of surgical repair for type Ⅲ PA/VSD was good. Preoperative evaluation of the pulmonary development and MAPCAs were helpful for choosing surgical options. Re-operation was recommended to those appropriate patients. Key words: Pulmonary atresia; Pulmonary artery development; Surgical options
