Abstract

Objective:

To review the experiences in repairing the anomalous origin of one pulmonary artery in infants.

Methods:

From March 2005 to May 2010, 11 infants diagnosed with anomalous origin of one pulmonary artery underwent surgical treatment. Their mean age was 12.7 months (two months to three years), and their mean body weight was 7.1 kg (4 to 13 kg). Seven patients had anomalous origin of the right pulmonary artery, and four patients had anomalous origin of the left pulmonary artery. All 11 patients had an intracardiac anomaly or vascular malformations as well as pulmonary hypertension. A median sternotomy and cardiopulmonary bypass (CPB) were used in all 11 patients. The mean follow-up was 20.5 months (6 to 60 months).

Results:

The operation time was 169 to 293 min (231 ± 55 min), the CPB time was 87 to 210 min (138 ± 47 min), and the aortic cross-clamp time was 45 to 133 min (86 ± 28 min). There was one hospital death (mortality 9%) in a patient with tetralogy of Fallot who had low cardiac output after the operation. In all cases, there was no application of artificial or homologous grafts. All surviving patients had satisfactory early to midterm results except for one patient with mild pulmonary stenosis.

Conclusion:

The surgical correction of anomalous origin of one pulmonary artery without artificial or homologous grafts has satisfactory early to midterm results in infants. doi: 10.1111/jocs.12456(J Card Surg 2015;30:85–91)
