Findings from a study by Nationwide Children's Hospital has revealed that infants born with complex congenital heart disease are at risk of developing a deadly bowel disease, besides serious heart-related complications. This is regardless of the type of surgical intervention they receive for their heart. (The findings of the study will also appear in the
Pediatric Critical Care Medicine, published online May 6 ahead of print.)
Necrotizing enterocolitis (NEC) is one of the most common and most life-threatening gastrointestinal diseases in newborn infants and involves inflammation that can destroy the intestine. While premature infants are at especially high risk for developing NEC, the bowel disease is also significantly more common in late preterm and term neonates with congenital heart disease.
"NEC and congenital heart disease are two distinct disease processes, but they appear to be inter-related, particularly in patients with the congenital heart condition known as hypoplastic left heart syndrome," said Wendy Luce, MD, the study's lead author and principal investigator in the Center for Perinatal Research at Nationwide Children's Hospital.
Research has shown that neonates undergoing the Norwood surgery for hypoplastic left heart syndrome (HLHS) have the highest risk for NEC of all congenital heart disease patients.
The hybrid approach has been developed at Nationwide Children's as an alternative strategy to the Norwood procedure for the management of HLHS and other forms of complex congenital heart disease. The hybrid approach shifts the risk of major open heart surgery and cardiopulmonary bypass to later in infancy. The incidence of NEC in patients undergoing the hybrid procedure has not been evaluated.
