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

Abstract

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.

An unexpected circular shunt: Novel method to treat semilunar valve insufficiency in a single ventricle patient on mechanical circulatory support

“…Previous reports have shown successful closure of the aortic valve in single ventricle disease palliated with a Norwood stage 1 and aortic insufficiency while maintaining neoaortic valve outflow 5,6 . Further, transcatheter closure of the aortic valve has been used as a method to ameliorate the effects of aortic insufficiency in adult patients with continuous‐flow LVADs 7 .…”

“…Previous reports have shown successful closure of the aortic valve in single ventricle disease palliated with a Norwood stage 1 and aortic insufficiency while maintaining neoaortic valve outflow. 5,6 Further, transcatheter closure of the aortic valve has been used as a method to ameliorate the effects of aortic insufficiency in adult patients with continuous-flow LVADs. 7 We present the first case of transcatheter closure of the pulmonic valve in a patient with HLHS treated with a hybrid stage 1 procedure who developed an iatrogenic circular shunt with both severe SVI and atrioventricular valve insufficiency.…”
