Hybrid Stage I Palliation in a I.I kg>, 28-Week Preterm Neonate With Posterior Malalignment Ventricular Septal Defect, Left Ventricular Outflow Tract Obstruction, and Coarctation of the Aorta

摘要

The hybrid stage I procedure has emerged as a less-invasive alternative to the standard surgical Norwood procedure in the palliation of high-risk hypoplastic left heart syndrome and variants. This approach may also benefit patients requiring complex neonatal repair who have significant anatomic and/or perioperative risk factors that either prevent or complicate durable and robust biven-tricular circulation from being safely achieved. An extremely low-birth weight (I.I kg) 28-week gestation preterm neonate with postnatal diagnosis of posterior malalignment ventricular septal defect, severe left ventricular outflow tract obstruction, aortic annular hypoplasia, and aortic arch obstruction underwent initial palliation with a hybrid stage I procedure. In this case, hybrid stage I palliation allowed for both somatic and left heart growth followed by ultimate uncomplicated biventricular repair.
