Abstract
Airway obstruction may complicate the course of infants undergoing repair of congenital heart disease. Airway obstruction was encountered in seven patients following surgery for complex congenital heart defects (two with interrupted aortic arch, one with pulmonary atresia and a ventricular septal defect, one with tetralogy of Fallot and an abnormal left anterior descending coronary artery, one with truncus arteriosus, and two with complex univentricular heart). In four patients, a conduit was implanted at the time of surgery. In all cases, bronchoscopy accurately demonstrated the cause of the airway obstruction. Two infants had hypoplasia of the left bronchus, and five had tracheobronchomalacia associated with extrinsic compression of the airway by a great vessel or conduit. All were treated conservatively with therapeutic bronchoscopy, tracheotomy, and/or stenting with prolonged mechanical ventilation. Follow-up ranged from 2 to 40 months. Four infants have been weaned from mechanical ventilation and decannulated; two are awaiting decannulation; and one was decannulated and died awaiting surgical repair. To reduce morbidity in infants undergoing surgery for congenital heart disease, the presence of preoperative airway anomalies should be sought and surgery planned to avoid airway compression. Conservative management using diagnostic and therapeutic bronchoscopy, tracheotomy, and stenting together with prolonged ventilator care is rewarding.
