Abstract

Assessment of recurrent coarctation after the Norwood procedure by routine measures is complicated by the unusual physiology caused by the presence of a modified Blalock-Tausig shunt with distal aortic arch obstruction. We present a new index that uses 2-dimensional measurement of the reconstructed aortic arch, which is highly sensitive and specific in identifying recurrent coarctation after the Norwood procedure in children with hypoplastic left heart syndrome.
