Treatment of Severe Native Left Pulmonary Artery Stenosis With Coronary Stent Implantation in a 2.4 kg Neonate.

A 1-month-old, 2.4 kg infant, previously born at 32 weeks gestation, was found to have a murmur while in the neonatal intensive care unit. The patient had ongoing feeding intolerance and required supplemental oxygen via nasal cannula. Cardiac computed tomography showed discrete stenosis of the proximal left pulmonary artery (LPA) with a normal-sized distal LPA. We describe the treatment course with transcatheter coronary stent implantation.
