Two cases of congenital cardiac anomaly associated with esophageal atresia and tracheo-esophageal fistula were presented. One case was HLHS, and the other was TAPVR. Esophageal procedures were performed earlier than cardiac procedures in both cases. Primary anastomosis for esophageal atresia just after birth in the latter case. Corrective procedures for cardiac anomalies were performed at 36 days and 35 days after birth, respectively. The HLHS case died perioperatively and the TAPVR case survived the operation and is alive one year postoperatively.
