Detailed Description
BACKGROUND:
Growth impairment is common in infants and children with congenital heart disease, most often in the presence of congestive heart failure and/or cyanosis. Growth failure is noted in many infants with a single ventricle who manifest both cyanosis and heart failure that commonly persist after palliative surgery. Whether this impairment is related to persistent or progressive abnormalities in cardiac structure and function is not known. ACE-Is are widely used in the treatment of infants with severe congestive heart failure to improve cardiac function and somatic growth. The ability of an ACE-I to improve somatic growth in infants with a single ventricle has not been previously studied.
This study has been approved by the Institutional Review Boards/Research Ethics Boards of all participating clinical centers:
Hospital for Sick Children, Toronto, Canada
Children's Hospital Boston, Boston, MA
Columbia College of Physicians and Surgeons, New York, NY
Children's Hospital of Philadelphia, Philadelphia, PA

DESIGN NARRATIVE:
This is a prospective, randomized, double-blind, placebo-controlled trial of ACE-I in infants with a single ventricle. After stratification by ventricular anatomy, neonates will be randomly assigned to receive enalapril or placebo and then followed for 14 months.
