RESUMEN
Though respiratory complications after cardiac surgery for congenital heart disease are common, and malformations of the diaphragm can be expected in these patients, the presence of an occult diaphragmatic defect unrecognisible preoperatively and complicating the post operative course is very rare and need a high index of suspicion for diagnosis in the setting of post operative respiratory failure. We present here a case of post operative respiratory failure from a delayed presenting diaphragmatic hernia in a 2-month-old boy who underwent corrective surgery for Taussig bing anomaly and hypoplastic aortic arch. Surgical repair of the diaphragmatic defect and reduction of the bowel loops to the abdomen resulted in rapid weaning from ventilation and recovery with subsequent discharge from hospital.
