High risk HLHS: hybrid approach yes, but how does it work?

Authors: Dietmar Schranz

Abstract

The majority of newborns with duct-dependent systemic blood flow are related to a hypoplastic left heart syndrome (HLHS), accounting for 2–3.5% of congenital heart defects (1). HLHS is anatomically subdivided in defects with stenosis or atresia of the mitral and aortic valve; consecutively left ventricular chamber size varies between fully diminished to almost normal dimensions in case of an associated VSD.
