Abstract
Right ventricular dysfunction is uncommon following surgical repair of dextrotransposition of great arteries (d-TGA) by the arterial switch procedure. Inhaled nitric oxide (iNO) is a specific pulmonary vasolidator that has proven successful in treating pulmonary hypertension when delivered via endotracheal tube. We present a five-month-old infant with d-TGA and ventricular septal defect (VSD) who developed pulmonary hypertensive crisis, causing severe right ventricular dysfunction with hemodynamic deterioration at day 6 postsurgical repair by VSD closure and arterial switch. He was successfully treated with iNO via nonrebreather face mask avoiding endotracheal reintubation. This modality should be considered in the management of such infants.
