Successful Truncal Valve Replacement With a Mechanical Valve After Bilateral Pulmonary Artery Banding.

Surgical management of truncus arteriosus, or common arterial trunk, has expanded over the past three decades to include earlier surgical intervention, initially during infancy and now chiefly in the neonatal period. Many studies have shown that preoperative truncal valve insufficiency is an independent risk factor for mortality. We herein present the case of a five-month-old boy with severe truncal valve insufficiency who underwent repair of common arterial trunk and prosthetic replacement of the truncal valve with associated annular enlargement after initial stabilization in the newborn period via palliative bilateral pulmonary artery banding. We believe that initial bilateral pulmonary artery banding represents a viable option for some cases of common arterial trunk involving truncal valve insufficiency.
