Neonatal Ross Procedure for Infective Endocarditis in a Dysplastic Aortic Valve After Pulmonary Artery Banding

Neonatal Ross procedure is rarely performed, especially in the setting of active infective endocarditis and prior pulmonary artery banding.

We present a rare case of a 2.5-month-old boy with a history of complex congenital heart disease, including aortic coarctation, severe aortic stenosis, and a ventricular septal defect, who developed infective endocarditis on a dysplastic bicuspid aortic valve.

This case highlights surgical decision-making and technical challenges in harvesting a pulmonary autograft after previous pulmonary artery banding in the presence of active infection.

Ross procedure can be feasible in neonates with complex anatomy and infection. Prior pulmonary artery banding increases technical complexity. Autograft resistance to reinfection supports its use in pediatric infective endocarditis.
