Ductal stenting with bilateral pulmonary artery banding as a life-saving management for hypoplastic left heart syndrome with congenital esophageal atresia: A case series

We present three cases of hypoplastic left heart syndrome (HLHS) complicated by congenital esophageal atresia and trachea-esophageal fistula (EA/TEF). The standard treatment for HLHS involves a staged surgical approach, eventually reaching Fontan completion. There is no report of patients with both HLHS and EA/TEF, and no established treatment strategy exists for such cases. Given the significant risk of simultaneously operating on HLHS and EA/TEF, we elected to pursue staged repair for each condition separately. Initially, soon after birth, we performed gastrostomy to secure the nutritional pathway for EA/TEF and stabilize breathing. Subsequently, we conducted bilateral pulmonary artery banding (bil-PAB) and ductal stenting for HLHS, as the Norwood operation carried an unacceptably high risk in these patients. Two of these patients were able to transition to home care, while the other patient died during hospitalization due to complications after EA repair. A combination of bil-PAB with ductal stenting for HLHS and staged repair for EA/TEF may provide effective management for patients with both conditions. Learning objective Hypoplastic left heart syndrome (HLHS) and congenital esophageal atresia (EA) are both life-threatening conditions that require early intervention after birth. There are few reports of patients with both conditions, and no treatment strategy is established. Although the procedure carries a high risk, we successfully performed ductal stenting with bilateral pulmonary artery banding for HLHS, as well as staged repair procedures for EA. Our approach may be a viable strategy for these conditions.
