Resection of an obstructive neonatal cardiac myxoma of the infundibulum.

Myxoma, the most common primary cardiac tumor in adults, is rare in neonates. We describe a myxoma arising from the infundibulum of the right ventricle causing significant outflow tract obstruction in an otherwise normal newborn. Serial echocardiograms revealed an increasing gradient across the right ventricular outflow tract prompting surgery. The patient underwent successful excision of the myxoma with an uneventful recovery.
