Early postoperative interventional aortic valve closure for severe aortic regurgitation in a neonate after Norwood procedure.

A neonate presented with signs of heart failure early after a Norwood procedure, due to increase of aortic and mitral valve regurgitation. Because repeated surgery was considered risky, we closed the aortic valve by catheter intervention with an Amplatzer Duct Occluder. Aortic regurgitation was abolished almost completely and the child improved. Unfortunately, 2 weeks after discharge, the patient died suddenly.
