Successful surgical repair of pulmonary dominant common arterial trunk without aortic arch obstruction in a neonate.

The pulmonary dominant variant of the common arterial trunk has always been reported to be associated with aortic coarctation, or interruption of the aortic arch, along with a duct-dependent systemic circulation. This mandates a complex surgical repair with attendant high surgical mortality. We report a 23-day-old baby with a pulmonary dominant trunk with mild aortic hypoplasia but with an arch free of coarctation or interruption, who underwent successful surgical repair.
