In patients with critical left ventricular outflow tract obstruction but adequately sized ventricles, the treatment of choice is biventricular repair. Several options have been proposed, including neonatal Yasui or Ross–Konno operation. However, each of these procedures carries a high mortality risk, especially in syndromic neonates. Here, we report the case of a patient with 22q11.2 deletion syndrome and a diagnosis of interrupted aortic arch type B2, ventricular septal defect and left ventricular outflow tract obstruction. As a means to avoid high-risk neonatal surgery in this patient, we pursued a strategy of delayed biventricular repair involving initial hybrid Norwood palliation followed by a Yasui-type operation at 3 months. Although this strategy turned out to be successful, proactive monitoring for the development of ductal stent stenosis during follow-up after the hybrid procedure remains crucial to prevent hemodynamic complications such as cardiac failure and systemic hypoperfusion.
