BACKGROUND Although newborn screening for critical congenital heart disease (CCHD) was recommended by the US Health and Human Services Secretary's Advisory Committee on Heritable Disorders in Newborns and Children to promote early detection, it was deemed by the Secretary of the HHS as not ready for adoption pending an implementation plan from HHS agencies.(More)
Incorporation of pulse oximetry to the assessment of the newborn infant can enhance detection of critical congenital heart disease (CCHD). Recently, the Secretary of Health and Human Services (HHS) recommended that screening for CCHD be added to the uniform screening panel. The American Academy of Pediatrics (AAP) has been a strong advocate of early(More)
OBJECTIVES We sought to evaluate the outcomes and identify risk factors for mortality after heart transplantation (HT) for congenital heart disease (CHD) in infants, children, and adults. BACKGROUND CHD is considered a risk factor for mortality after HT, yet this unique group of patients represents a spectrum of complexity. METHODS There were 488(More)
BACKGROUND The major limiting factor to successful heart transplantation in infants is the limited supply of donors. To examine the impact of donor limitations on survival after listing, a multiinstitutional study was designed to identify risk factors for death while waiting and for longer interval to transplantation. METHODS Between January 1 and(More)
OBJECTIVES The purpose of this investigation was to determine whether myocardial blood flow and flow reserve, based on quantitative measurements derived from positron emission tomographic (PET) imaging, would be globally impaired in children with a previous history of Kawasaki disease and normal epicardial coronary arteries. BACKGROUND Kawasaki disease is(More)
Severe tricuspid regurgitation resulting from a flail leaflet is a rare cause of neonatal cyanosis. We report two neonates with profound cyanosis and severe tricuspid regurgitation caused by rupture of the papillary muscle supporting the anterior leaflet, without other structural heart defects. Ductal patency could not be established. Repair of the(More)
A member of the Tennessee state legislature recently proposed a bill that would mandate all newborn infants to undergo pulse oximetry screening for the purpose of identifying those with critical structural heart disease before discharge home. The Tennessee Task Force on Screening Newborn Infants for Critical Congenital Heart Defects was convened on(More)
It has been speculated that neonatal coarctation results from postnatal constriction of the aortic isthmus and ductus arteriosus. However, aortic arch hypoplasia is present in some neonates with coarctation and is presumed to be due to decreased aortic arch blood flow in utero. To measure the degree of aortic arch hypoplasia and to analyze the distribution(More)

BACKGROUND Infants with hypoplastic left heart syndrome (HLHS) commonly undergo cardiac transplantation as primary management. METHODS We examined outcomes of primary transplantation for unpalliated HLHS. We analyzed data from the 20 institutions of the Pediatric Heart Transplant Study Group, from January 1, 1993, through December 31, 1998, using(More)
