Background: Single-stage biventricular repair remains a challenging and difficult decision in high-risk newborns and early infants with the presence of left ventricular outflow tract obstruction (LVOTO) or borderline hypoplasia of the left ventricle (LV). Methods: Six high-risk patients underwent the initial hybrid procedure (bilateral pulmonary banding + ductal stenting) for staged biventricular repair. Their median age was 17 days (range: 7-55 days). The diagnosis was interrupted aortic arch (IAA), ventricular septal defect (VSD), and LVOTO (n = 3); IAA and VSD (n = 1); and aortic annular hypoplasia, aortic arch hypoplasia, VSD, and LVOTO (n = 1). The last patient had borderline LV with large atrial septal defect (ASD) and aortic arch hypoplasia. The patient with borderline LV had also ASD closure with small fenestration. Results: One patient died of sepsis after the hybrid procedure. Other patients underwent biventricular repair 8 to 13 months later. Three patients had conventional repair with conal septum resection. The other patient with IAA, in whom LVOTO was considered nonresectable, underwent Yasui operation. The last patient with borderline LV had enough development of left heart structures during follow-up and underwent aortic arch repair. One patient who had conal septum resection died after biventricular repair. One patient needed a tracheostomy; four patients were discharged uneventfully and their clinical conditions were good on postoperative year 1. Conclusion: Staged biventricular repair with the initial hybrid procedure may be a feasible and safe alternative in high-risk neonates and early infants. Hybrid intervention may provide the development of cardiac structures in time and a better evaluation for the possibility of biventricular repair in borderline patients.
