Melody Mitral Valve Is a Promising Alternative to Mechanical Valve Replacement for Young Children.

Purpose: The purpose of this study was to compare outcomes of Melody mitral valve to mechanical mitral valve replacement (MVR) for young children.

Description: Children who underwent Melody MVR from 2014 to 2020 were case-matched to mechanical MVR patients. Transplant-free survival and cumulative incidence of reintervention were compared.

Low descending aorta flow is associated with adverse feeding outcomes in neonates with small left-sided structures.

Feeding intolerance and necrotizing enterocolitis (NEC) cause significant morbidity in neonates with duct-dependent systemic circulations. Whether these complications are associated with low blood flow to the bowel is unproven. The aim of this study was to determine whether low descending aortic (DAO) flow is associated with adverse feeding outcomes in neonates with small left-sided structures, including borderline left ventricle and hypoplastic left heart syndrome (HLHS).
