Surgical treatment of critical and complex congenital heart defects in small infants / 中华胸心血管外科杂志

ABSTRACT

Ovbective To evaluate the outcome of the complete repair for critical and complex congenital heart defects in small infants with cardiopulmonary bypass. Methods A retrospective review of hospital records was performed for 187 infants under 6 months undergone cardiac operation from January 2000 to January 2004. Average age was (4.15?2.32) months (3d-6months) and average weight was (4.42?0.56)kg (3～7kg). The diagnoses included ventricular septal defect with pulmonary hypertension,transposition of the great arteries,aortic coarctation with other lesions,total anomalous pulmonary venous connection,tetralogy of Fallot,atrioventricular canal defect,pulmonary atresia,and neonatal cardiac tumor. Average duration of mechanical ventilation was (17.5?9.7) hours. ICU stay was (4.9?1.5) days. Results 9 cases died after operation with a hospital mortality of 4.81%. Postoperative complications included low cardiac output syndrome,residual shunt,pulmonary infection and pulmonary hemorrhage. 178 are alive and in good cardiac status at follow-up of 4～48 months. After repair,growth approximates the normal. Conclusion With the development of pediatric cardiac surgery, cardiac operation with CPB in small infants with critical and complex congenital heart defects is feasible and may provide satisfactory survival.
