Abstract
BACKGROUND AND PURPOSE Brain MRI of newborns with congenital heart disease show signs of immaturity relative to healthy controls. Our aim was to determine whether the semiquantitative fetal total maturation score can detect abnormalities in brain maturation in fetuses with congenital heart disease in the second and third trimesters. MATERIALS AND METHODS We analyzed data from a prospective study of fetuses with and without congenital heart disease who underwent fetal MR imaging at 25-35 weeks' gestation. Two independent neuroradiologists blinded to the clinical data reviewed and scored all images using the fetal total maturation score. Interrater reliability was evaluated by the intraclass correlation coefficient using the individual reader scores, which were also used to calculate an average score for each subject. Comparisons of the average and individual reader scores between affected and control fetuses and relationships with clinical variables were evaluated using multivariable linear regression. RESULTS Data from 69 subjects (48 cardiac, 21 controls) were included. High concordance was observed between readers with an intraclass correlation coefficient of 0.98 (95% CI, 0.97-0.99). The affected group had significantly lower fetal total maturation scores than the control group (β-estimate, -0.9 [95% CI, -1.5 to -0.4], P = .002), adjusting for gestational age and sex. Averaged fetal total maturation, germinal matrix, myelination, and superior temporal sulcus scores were significantly delayed in fetuses with congenital heart disease versus controls (P < .05 for each). The fetal total maturation score was not significantly associated with any cardiac, anatomic, or physiologic variables. CONCLUSIONS The fetal total maturation score is sensitive to differences in brain maturation between fetuses with isolated congenital heart disease and healthy controls.

Abstract
Neurologic impairment is a major complication of complex congenital heart disease (CHD). A growing body of evidence suggests that neurologic dysfunction may be present in a significant proportion of this high-risk population in the early newborn period prior to surgical interventions. We recently provided the first evidence that brain growth impairment in fetuses with complex CHD has its origins in utero. Here, we extend these observations by characterizing global and regional brain development in fetuses with hypoplastic left heart syndrome (HLHS), one of the most severe forms of CHD. Using advanced magnetic resonance imaging techniques, we compared in vivo brain growth in 18 fetuses with HLHS and 30 control fetuses from 25.4-37.0 weeks of gestation. Our findings demonstrate a progressive third trimester fall-off in cortical gray and white matter volumes (P < 0.001), and subcortical gray matter (P < 0.05) in fetuses with HLHS. Significant delays in cortical gyrification were also evident in HLHS fetuses (P < 0.001). In the HLHS fetus, local cortical folding delays were detected as early as 25 weeks in the frontal, parietal, calcarine, temporal, and collateral regions and appear to precede volumetric brain growth disturbances, which may be an early marker of elevated risk for third trimester brain growth failure.

Abstract
Most contemporary diagnostic and treatment strategies for pediatric patients with cardiovascular disease are not supported by evidence from clinical trials but instead are based on expert opinion, single-institution observational studies, or extrapolated from adult cardiovascular medicine. In response to this concern, the National Heart, Lung, and Blood Institute established the Pediatric Heart Disease Clinical Research Network (PHN) in 2001. The purposes of this article are to describe the initiation, structure, and function of the PHN; to review the ongoing studies; and to address current and future challenges. To date, four randomized clinical trials and two observational studies have been launched. Design and conduct of complex, multicenter studies in children with congenital and acquired heart disease must address numerous challenges, including identification of an appropriate clinically relevant primary endpoint, lack of preliminary data on which to base sample size calculations, and recruitment of an adequate number of subjects. The infrastructure is now well developed and capable of implementing complex, multicenter protocols efficiently and recruiting subjects effectively. The PHN is uniquely positioned to contribute to providing evidence-based medicine for and improving the outcomes of pediatric patients with cardiovascular disease.

Abstract
Several compelling lines of evidence suggest an important influence of genetic variation in susceptibility to Kawasaki disease (KD), an acute vasculitis that causes coronary artery aneurysms in children. We performed a family-based genotyping study to test for association between KD and 58 genes involved in cardiovascular disease and inflammation. By analysis of a cohort of 209 KD trios using the transmission disequilibrium test, we documented the asymmetric transmission of five alleles including the interleukin-4 (IL-4) C(-589)T allele (P=0.03). Asymmetric transmission of the IL-4 C(-589)T was replicated in a second, independent cohort of 60 trios (P=0.05, combined P=0.002). Haplotypes of alleles in IL-4, colony-stimulating factor 2 (CSF2), IL-13, and transcription factor 7 (TCF7), all located in the interleukin gene cluster on 5q31, were also asymmetrically transmitted. The reported associations of KD with atopic dermatitis and allergy, elevated serum IgE levels, eosinophilia, and increased circulating numbers of monocyte/macrophages expressing the low-affinity IgE receptor (FCepsilonR2) may be related to effects of IL-4. Thus, the largest family-based genotyping study of KD patients to date suggests that genetic variation in the IL-4 gene, or regions linked to IL-4, plays an important role in KD pathogenesis and disease susceptibility.

Abstract
Kawasaki disease (KD) is an acute febrile syndrome of childhood, characterized by vasculitis of the medium-sized arteries. White blood cell counts and the inflammatory parameter C-reactive protein (CRP) are known to be elevated in the acute phase of the disease. In this study we investigated the course of inflammatory cell type-specific parameters in KD over a longer period of time. Plasma levels of human neutrophil elastase (HNE), matrix metalloproteinases-2 and -9 (MMP2, MMP9), and neutrophil gelatinase-associated lipocalin (NGAL), macrophage neopterin and CRP were measured. Plasma samples were collected in the acute, subacute and early convalescent stage, and three months after the onset of disease. Median CRP and neopterin normalized within two weeks. In contrast, six weeks and three months after onset of disease, levels of HNE were still elevated, with median values of 163 ng/ml and 156 ng/ml, respectively (control children median < 50 ng/ml; for all time-points P < 0.0001). Values of NGAL correlated with the levels of HNE (r = 0.39, P = 0.013). These results demonstrate a longer state of neutrophil activation in KD than was previously assumed. The potential relationship between this prolonged neutrophil activation, coronary artery lesion formation and their persistence, as well as the risk of premature atherosclerosis warrants further evaluation.

Abstract
BACKGROUND To study the long-term impact on general health status of D-transposition of the great arteries (D-TGA) after the arterial switch operation (ASO) during infancy, we asked parents to complete the Child Health Questionnaire, Parent Form-50 when their children were 8 years old. METHODS AND RESULTS Of 160 eligible patients, questionnaires were completed for 155 subjects (96%). Median age at surgery was 6 days (range 1 to 67 days), and median age at completion of the Child Health Questionnaire was 8.1 years (7.6 to 10.0 years). Subsequent to questionnaire completion, children underwent psychometric testing. Mean Physical Health Summary and Psychosocial Summary scores were 54.0+/-6.1 and 49.7+/-9.9, respectively, which were similar to those of normal subjects. Compared with the normative sample, parents of D-TGA patients reported more problems with attention, learning, and speech, as well as greater frequency of developmental delay (P<0.001 for each). Worse Psychosocial Summary scores were significantly associated with lower full-scale IQ (P=0.001) and lower achievement in reading (P=0.005) and math (P=0.007). Worse Physical Health Summary scores were associated with longer hospital stay after the ASO (P=0.02). General health status scores were not significantly related to presence of ventricular septal defect, age at surgery, perfusion variables during the ASO, sex, or history of cardiac reoperation. CONCLUSIONS At age 8 years, children with D-TGA after ASO have an overall physical and psychosocial health status similar to that of the general population. Lower IQ and academic achievement are associated with worse psychosocial health status, whereas longer hospital course after initial surgery is associated with worse physical health status.

Abstract
Genetic polymorphisms influence the magnitude of the cytokine response after an inflammatory stimulus. To determine whether such polymorphisms might play a role in Kawasaki disease (KD), we analyzed white and Japanese children with KD and control populations for two polymorphic loci in which the A allele is associated with high tumor necrosis factor-alpha secretion. The lymphotoxin-alpha+250 A/A genotype was overrepresented among white children with KD compared with controls (0.59 versus 0.36; p = 0.013). The tumor necrosis factor-alpha-308 A/G genotype was overrepresented among whites with KD who had coronary artery abnormalities compared with those with normal echocardiograms (0.36 versus 0.09; p = 0.044). No significant difference was seen at either locus between Japanese children with KD and Japanese controls. The increased frequency of the high secretor alleles in white children with KD suggests that these loci may be related to susceptibility to KD and to outcome after disease.

Abstract
OBJECTIVES To examine work-family balance issues and predictors of stress related to work-family balance among pediatric house staff and faculty. METHODS Data were obtained through an anonymous mail survey. Univariate analyses assessed associations between work-family issues (work-related factors that affect work-family balance, perceived support, work-family--related stress, and proposed solutions) and the following variables: gender, parental status, working status of spouse, and academic rank. Multiple linear regression examined independent predictors of perceived stress. RESULTS Fifty percent of the 327 respondents cared for dependent children, and 20% expected to care for an elderly person in the next 5 years. Only 5% strongly agreed that their division or department was concerned about supporting members' work-family balance, and 4% strongly agreed that existing programs supported their needs. Eighty-three percent reported feeling stressed as a result of efforts to balance work and family. Independent predictors of stress included perceived need to choose between career and family, increasing age, dependent children, less support from colleagues and supervisors, and female gender. CONCLUSIONS Work-family balance issues are responsible for substantial perceived stress. Academic departments should consider a commitment to supporting faculty who are struggling with these issues, including creation of work-family policies and programs, development of mentoring systems, and reexamination of existing expectations for work practices.

Abstract
OBJECTIVES In a randomized single-center trial, we compared developmental and neurologic outcomes at 1 and 2 to 4 years of age in children who underwent reparative cardiac operations at less than 9 months of age after use of the alpha-stat versus pH-stat strategy during deep hypothermic cardiopulmonary bypass. METHODS Among 168 children eligible for follow-up, 1-year developmental evaluations were carried out on 111, neurologic evaluations on 110, and electroencephalographic evaluations on 102. Parents of 122 children completed questionnaires on behavior and development when children were 2 to 4 years of age. RESULTS The Psychomotor Development Index scores of the alpha-stat and pH-stat groups did not differ significantly (P =.97). For Mental Development Index scores, the treatment group effect differed according to diagnosis (P =.007). In the D -transposition of the great arteries (n = 59) and tetralogy of Fallot (n = 36) subgroups, the pH-stat group had slightly higher Mental Development Index scores than the alpha-stat group, although these differences were not statistically significant. In the ventricular septal defect subgroup (n = 16), the alpha-stat group had significantly higher scores. Psychomotor Development Index and Mental Development Index scores were significantly higher in the group with D -transposition of the great arteries than in the other 2 groups (P =.03 and P =.01, respectively). Across all diagnoses, Mental Development Index scores were significantly higher than Psychomotor Development Index scores (P <.001). Treatment group assignment was not significantly associated with abnormalities on neurologic examination (P =.70) or electroencephalographic examination (P =.77) at 1 year or with parents' ratings of children's development (P =.99) or behavior (P =.27) at age 2 to 4 years. CONCLUSIONS Use of alpha-stat versus pH-stat acid-base management strategy during reparative infant cardiac operations with deep hypothermic cardiopulmonary bypass was not consistently related to either improved or impaired early neurodevelopmental outcomes.

Abstract
We describe 10 patients who developed a psoriatic skin eruption during either the acute or convalescent phase of Kawasaki disease. The skin eruption was pustular in 3 patients, but more typical psoriasiform skin lesions were seen in the remaining 7 patients. No patient has yet developed chronic psoriasis.

Abstract
BACKGROUND Patients with a single ventricle have multiple risk factors for central nervous system injury, both before and after the Fontan procedure. METHODS AND RESULTS A geographically selected cohort was invited to undergo standardized testing, including age-appropriate measures of intelligence quotient (IQ) and achievement tests. Historical information was obtained by chart review and patient questionnaires. Of the 222 eligible patients, 133 (59.9%) participated. Median age at testing was 11.1 years (range, 3. 7 to 41.0 years), 6.0 years (range, 1.6 to 19.6 years) after surgery. Mean full-scale IQ was 95.7+/-17.4 (P<0.006 versus normal); 10 patients (7.8%) had full-scale IQ scores <70 (P=0.001). After adjustment for socioeconomic status, lower IQ was associated with the use of circulatory arrest before the Fontan operation (P=0.002), the anatomic diagnoses of hypoplastic left heart syndrome (P<0.001) and "other complex" (P=0.05), and prior placement of a pulmonary artery band (P=0.04). Mean composite achievement score was 91.6+/-15. 4 (P<0.001 versus normal); 14 patients (10.8%) scored <70 (P<0.001). After adjustment for socioeconomic status, independent risk factors for low achievement scores included the diagnoses of hypoplastic left heart syndrome (P=0.004) and "other complex" (P=0.003) or prior use of circulatory arrest (P=0.03), as well as a reoperation with cardiopulmonary bypass within 30 days of the Fontan (P=0.01). CONCLUSIONS Most individual patients palliated with the Fontan procedure in the 1970s and 1980s have cognitive outcome and academic function within the normal range, but the performance of the cohort is lower than that of the general population.

Abstract
Kawasaki disease is the leading cause of acquired heart disease in childhood. Despite treatment with intravenous gamma globulin, 2% to 4% of patients have coronary abnormalities. Those with giant aneurysms are at risk for stenosis and myocardial ischemia/infarction, and require aggressive anticoagulation with frequent follow-up, including stress testing and coronary angiography. In rare cases, patients will have coronary artery bypass grafting. Those with less severe coronary involvement need antiplatelet therapy and infrequent noninvasive testing. Patients with normal echos after the acute phase are not treated, but the future impact of the disease is not certain particularly in the setting of adult onset coronary artery disease.

Abstract
CONTEXT Managed care plans aggressively seek to contain costs, but few data are available regarding their impact on access to high quality care for their members. OBJECTIVE To assess the impact of managed care health insurance on use of lower-mortality hospitals for children undergoing heart surgery in California. DESIGN Retrospective cohort study using state-mandated hospital discharge datasets. SETTING Pediatric cardiovascular surgical centers in California. PATIENTS Five thousand seventy-one children admitted for open cardiac surgical procedures during 1992-1994. RESULTS Hospitals were divided into lower- and higher-mortality groups according to adjusted surgical mortality. Using multivariate logistic regression analysis to control for medical, socioeconomic, demographic, and distance factors, children with managed care insurance were less likely to be admitted to a lower-mortality hospital for surgery relative to children with indemnity insurance (odds ratio:.53; 95% confidence interval:.45,.63). Similar findings resulted when the analysis was stratified by race/ethnicity. In addition, length of stay, a correlate of health care costs, was no longer for children admitted to lower-mortality centers than for those at higher-mortality centers (adjusted difference:.54 days shorter at lower-mortality centers; 95% confidence interval: -1.50,. 41). CONCLUSIONS During this study, children with managed care insurance had significantly reduced use of lower-mortality hospitals for pediatric heart surgery in California compared with children with indemnity insurance. Further study is necessary to determine the mechanisms of this apparent insurance-specific inequity.

Abstract
CONTEXT Explicit information about the quality of coronary artery bypass graft (CABG) surgery has been available for nearly a decade in New York State; however, the extent to which managed care insurance plans direct enrollees to the lowest-mortality CABG surgery hospitals remains unknown. OBJECTIVE To compare the proportion of patients with managed care insurance and fee-for-service (FFS) insurance who undergo CABG surgery at lower-mortality hospitals. DESIGN A retrospective cohort study of CABG surgery discharges from 1993 to 1996, using New York Department of Health databases and multivariate analysis to estimate the use of lower-mortality hospitals by patients with different types of health insurance. SETTING Cardiac surgical centers in New York, of which 14 were classified as lower-mortality hospitals (mean rate, 2.1%) and 17 were classified as higher-mortality hospitals (mean rate, 3.2%). PATIENTS A total of 58,902 adults older than 17 years who were hospitalized for CABG surgery. Patients were excluded if their CABG surgery was combined with any valve procedure or left ventricular aneurysm resection or if they were younger than 65 years and enrolled in Medicare FFS or Medicare managed care. MAIN OUTCOME MEASURE Probability of a patient receiving CABG surgery at a lower-mortality hospital. RESULTS Compared with patients with private FFS insurance (n = 18,905), patients with private managed care insurance (n=7169) and Medicare managed care insurance (n=880) were less likely to receive CABG surgery at a lower-mortality hospital (relative risk [RR] of surgery at a lower-mortality hospital compared with patients with private FFS insurance, 0.77; 95% confidence interval [CI], 0.74-0.81; P<.001; and RR, 0.61; 95% CI, 0.54-0.70; P<.001, respectively, after controlling for multiple potential confounding factors). Patients with Medicare FFS insurance used lower-mortality hospitals at rates more similar to those with private FFS insurance (n = 31,948; RR, 0.95; 95% CI, 0.91-0.98; P=.004). CONCLUSIONS Patients in New York State with private managed care and Medicare managed care insurance were significantly less likely to use lower-mortality hospitals for CABG surgery compared with patients with private FFS insurance.

Abstract
BACKGROUND The time course and rate of recovery of myocardial dysfunction in association with Kawasaki disease in response to intravenous gamma-globulin is unknown and may provide mechanistic clues. METHODS AND RESULTS The acute changes in myocardial contractility in 25 patients with Kawasaki disease were evaluated by noninvasive stress-shortening and stress-velocity analysis. Echocardiograms were performed before and then daily for 4 days during which the patients received gamma-globulin 1.6 to 2 g/kg. Before treatment, contractility was abnormally low (<2 SD) in 14 patients (56%). Contractility increased significantly (2 SD increase) in 17 (68%), including 13 of 14 with depressed contractility and 4 whose initial contractility fell within normal limits. Of the 14 patients with depressed contractility, 8 (57%) normalized within 24 hours and a further 5 (35.7%) normalized within 6 months. A clinical response to treatment (fall in C-reactive protein by 50% and/or resolution of fever within 4 days) was seen in 22 patients (88%). Contractility increased in 17 of the 22 clinical responders and was normal before therapy in the other 5. The 3 patients who did not respond clinically also had no change in contractility with gamma-globulin therapy. Long-term (more than 12 months) follow-up was available in 19 patients. All patients had normal contractility at late follow-up. CONCLUSIONS More than half the patients with Kawasaki disease have abnormal contractility at presentation. Myocardial response to gamma-globulin therapy is associated with rapid improvement in myocardial mechanics, with a high concordance between the clinical and myocardial response to therapy. The speed of recovery suggests that depressed contractility in patients with Kawasaki disease is caused by a rapidly reversible process such as circulating toxins or activated cytokines. Long-term outcome is good even in those patients with slow recovery of myocardial function.

Abstract
BACKGROUND The assessment of the impact of cardiopulmonary bypass (CPB) on developmental outcomes in children who undergo open heart surgery is hampered by the absence of a suitable comparison group. The development of interventional catheterization techniques for the repair of certain types of congenital heart lesions provides the opportunity to study children who have not been exposed to CPB. METHODS AND RESULTS We performed standardized neuropsychological testing on children after closure of a secundum atrial septal defect through the use of surgery (n=26) or a transcatheter device (n=19). Device patients, compared with surgical patients, were similar in age at defect closure (mean, 6 years) but older at follow-up testing (12.3 versus 10.6 years). The mean weight percentile at closure was greater and the defect size was smaller in the device patients. Families of device patients tended to have a higher parent IQ, higher level of maternal education, and higher level of maternal occupation. In general, however, children's IQ and achievement scores were in the normal range for both groups. In regression analyses with adjustment for age at testing and parent IQ, surgical repair was associated with a 9.5-point deficit in Full-Scale IQ (P=0. 03) and a 9.7-point deficit in Performance IQ (P=0.05). Block Design was the IQ subtest on which treatment groups differed the most (P=0. 01). Surgical patients achieved significantly better scores on errors of commission (P=0.05) and attentiveness index (P=0.03) on a continuous performance test of attention. Scores on tests of achievement and other neuropsychological domains did not differ significantly between the groups. Regression analyses within the surgical group failed to identify significant CPB-related risk factors. CONCLUSIONS A prospective randomized trial or a study that includes prerepair and postrepair assessments is necessary to establish whether the observed advantages of device closure in neuropsychological outcome represent deleterious effects of CPB or a methodological artifact.

Abstract
Kawasaki disease is a leading cause of acquired heart disease in children in the USA. An acute vasculitis of unknown etiology, it occurs predominantly in infancy and early childhood, and more rarely in teenagers. Coronary artery aneurysms or ectasia develop in approximately 15-25% of children with the disease. Treatment with intravenous gamma globulin, 2 g per kg, in the acute phase reduces this risk three- to fivefold. Angiographic resolution occurs in approximately one-half of aneurysmal arterial segments, but these show persistent histologic and functional abnormalities. The remainder continue to be aneurysmal, often with development of progressive stenosis or occlusion. The worst prognosis occurs in children with so-called 'giant aneurysms', i.e. those with a maximum diameter greater than 8 mm, because thrombosis is promoted both by sluggish blood flow within the massively dilated vascular space and by the frequent development of stenotic lesions. Serial stress tests with myocardial imaging are mandatory in the management of patients with Kawasaki disease and significant coronary artery disease to determine the need for coronary angiography and transcatheter interventions or coronary bypass surgery. Continued long-term surveillance in patients with and without detected coronary abnormalities is necessary to determine the natural history of Kawasaki disease.

Abstract
BACKGROUND It is not known whether developmental and neurological outcomes in the preschool period differ depending on whether the predominant vital organ support strategy used in infant heart surgery was total circulatory arrest (CA) or low-flow cardiopulmonary bypass. METHODS AND RESULTS Infants with D-transposition of the great arteries who underwent an arterial-switch operation were randomly assigned to a support method consisting predominantly of CA or low-flow cardiopulmonary bypass. Developmental and neurological status were evaluated blindly at 4 years of age in 158 of 163 eligible children (97%). Neither IQ scores nor overall neurological status were significantly associated with either treatment group or duration of CA. The CA group scored lower on tests of motor function (gross motor, P=0.01; fine motor, P=0.03) and had more severe speech abnormalities (oromotor apraxia, P=0.007). Seizures in the perioperative period, detected either clinically or by continuous electroencephalographic monitoring, were associated with lower mean IQ scores (12.6 and 7.7 points, respectively) and increased risk of neurological abnormalities (odds ratios, 8.4 and 5.6, respectively). The performance of the full cohort was below expectations in several domains, including IQ, expressive language, visual-motor integration, motor function, and oromotor control. CONCLUSIONS Use of CA to support vital organs during open heart surgery in infancy is associated, at the age of 4 years, with worse motor coordination and planning but not with lower IQ or with worse overall neurological status.

Abstract
UNLABELLED Varying degrees of hemodilution are used during deep hypothermic cardiopulmonary bypass. However, the optimal hematocrit (Hct) level to ensure adequate oxygen delivery without impairing microcirculatory flow is not known. In this prospective, randomized study, cerebral blood flow velocity in the middle cerebral artery was measured using transcranial Doppler sonography in 35 neonates and infants undergoing surgery with deep hypothermic cardiopulmonary bypass. Patients were randomized to low Hct (aiming for 20%) or high Hct (aiming for 30%) during cooling on cardiopulmonary bypass (CPB). Systolic (V(s)), mean (Vm), and diastolic (Vd) cerebral blood flow velocity, as well as pulsatility index (PI = [V(s) - Vd]/Vm) and resistance index (RI = [V(s) - Vd]/V(s)) were recorded at six time points: postinduction, at cannulation, after 10 min cooling on CPB, rewarmed to 35 degrees C on CPB, immediately off CPB, and at skin closure. Vm was significantly lower in the high Hct group compared with that in the low Hct group during cooling (P < 0.01). Postinduction, the high Hct group demonstrated significantly lower Vd immediately off CPB (P < 0.01) and significantly lower Vm and V(s) at skin closure (P < 0.001). We conclude that there is an inverse relation between hematocrit and cerebral blood flow velocity during deep hypothermic cardiopulmonary bypass in neonates and infants. IMPLICATIONS There is an inverse relation between hematocrit and cerebral blood flow velocity during deep hypothermic cardiopulmonary bypass in neonates and infants. Further studies correlating Hct and cerebral blood flow velocity with cerebral metabolic rate and neurologic outcome are necessary to determine the optimal Hct during deep hypothermic cardiopulmonary bypass.

Abstract
We sought to determine the impact of prenatal diagnosis on the perioperative outcome of newborns with hypoplastic left heart syndrome (HLHS) and transposition of the great arteries (TGA). All neonates with HLHS or TGA encountered at Children's Hospital, Boston, Massachusetts, from January 1988 to May 1996 were identified and outcomes documented. Birth characteristics, preoperative, operative, and postoperative variables of term newborns with a prenatal diagnosis of HLHS or TGA who underwent a Norwood operation (n = 27) or arterial switch operation (n = 14), respectively, were compared with newborns with a postnatal diagnosis of HLHS (n = 47) or TGA (n = 28) who had undergone surgery. Of 217 neonates with HLHS and 422 with TGA, 39 and 16, respectively, had a prenatal diagnosis. The preoperative mortality among neonates aggressively managed did not differ between the prenatal and postnatal diagnosis groups for either HLHS or TGA (p >0.05). Neonates with a prenatal diagnosis who underwent surgery had objective indicators of lower severity of illness preoperatively, including a higher lowest recorded pH (p = 0.03), lower maximum blood urea nitrogen (p = 0.002), and creatinine (p = 0.03) among newborns with HLHS, and a tendency toward higher minimum of partial pressure of arterial oxygen in the TGA group (p = 0.06). Prenatal diagnosis was not associated with an improved postoperative course or operative mortality (p <0.05) within a diagnostic group. Thus, a prenatal diagnosis improves the preoperative condition of neonates with HLHS and TGA, but may not significantly improve preoperative mortality or early postoperative outcome among neonates managed at a tertiary care center.

Abstract
OBJECTIVE To determine the prevalence and outcome of intravenous gamma-globulin (IVIG) retreatment in patients with Kawasaki disease (KD). METHOD Multicenter, retrospective survey of all children with KD evaluated at nine clinical centers across North America during a 15-month period. RESULTS Data were available for 378 patients. At 48 h after completion of the initial IVIG infusion, 50 patients (13.2%) remained febrile, 29 (58.0%) of whom were retreated with IVIG, including 4 (13.8%) with coronary artery abnormalities before their first IVIG infusion. Among 25 retreated patients with a normal baseline echocardiogram, 5 (20.0%) developed coronary abnormalities and were termed "treatment failures." Among the 323 patients with a normal baseline echocardiogram, only 9 (2.8%) were treatment failures; treatment failure occurred in 4 of 282 (1.4%) patients who became afebrile post-IVIG and in 5 of 41 (12.2%) patients with persistent or recrudescent fever after their first course of IVIG therapy (P=0.002). CONCLUSIONS The overall prevalence of new coronary abnormalities in KD patients treated with IVIG and aspirin remains low. Persistent or recrudescent fever after the first course of IVIG was associated with an increased risk of treatment failure (P=0.002). IVIG retreatment in patients who remain febrile after the first course of IVIG is now common (58.0%), although the efficacy of this practice requires assessment with a randomized trial.

Abstract
BACKGROUND To determine the validity of the newly assigned work relative value unit (RVU) scale for surgical procedures for congenital heart disease, we measured its relationship to length of hospital stay, total hospital charges, and mortality. METHODS We identified cases by the presence of ICD-9-CM codes in nine statewide, administrative hospital discharge abstract databases for 1992. Computer algorithms were generated to assign RVUs to individual cases. Spearman correlation coefficients between work and practice expense RVUs and median length of hospital stay, total hospital charges, and in-hospital mortality were determined, as well as parameter estimates from linear and logistic regression. RESULTS Using data from 5,192 cases involving 34 surgical procedures for congenital heart disease, higher work RVUs were associated with longer lengths of hospital stay (rs = 0.72, p < 0.0001), higher total hospital charges (rs = 0.81, p < 0.0001), and higher in-hospital mortality (rs = 0.45, p = 0.01). A 5-point increase in the relative value scale was associated with an increase in the length of stay by a multiplicative factor of 1.3 (p < 0.0001); total hospital charges by 1.5 (p < 0.0001); and the odds of in-hospital death by 1.9 (p < 0.0001). Findings were similar for practice expense RVUs, as work and practice expense RVUs were highly correlated (rs = 0.93, p < 0.0001). CONCLUSIONS The group of work RVUs for surgical procedures for congenital heart defects are reasonable relative measures, on average, of physician work for these procedures, thus supporting the use of this scale to determine physician reimbursement. Practice expense RVUs may not be an independent measure for these procedures.

Abstract
BACKGROUND Low-density lipoprotein cholesterol (LDL-C) levels are the primary basis for treatment guidelines established for hyperlipidemic children and adolescents. Levels of LDL-C are commonly monitored by means of the Friedewald formula, an indirect calculation that requires an overnight fast. A new method has been developed for the direct measurement of LDL-C (DLDL-C) that does not require fasting. We evaluated the clinical utility of this method. DESIGN We determined LDL-C concentrations simultaneously by the DLDL-C method, Friedewald equation, and beta-quantification (reference procedure). SETTING Pediatric dyslipidemia clinic at Children's Hospital, Boston, Mass. PATIENTS Ninety-two fasting hyperlipidemic pediatric patients. RESULTS At the LDL-C concentration cutoffs commonly used for making therapeutic decisions, the DLDL-C method had a significant negative bias (P< or =.05) and misclassified patients into incorrect treatment groups more often than the Friedewald method. The negative predictive value for the DLDL-C method was lower than that for the Friedewald method (P< or =.05), and the cost of determining LDL-C level with the new method was 3 times greater. CONCLUSIONS The misclassification potential for LDL-C, and the assay costs, were greater for the DLDL-C method than for the Friedewald calculation. Despite the apparent advantages of the DLDL-C method, we conclude that for hyperlipidemic children the utility of this new method is not advantageous over the conventional Friedewald method. In some conditions, such as in diabetes or marked hypertriglyceridemia, the DLDL-C method may be useful.

Abstract
BACKGROUND Current American Heart Association guidelines indicate that patients with Kawasaki disease and no coronary artery abnormalities on echocardiography at any stage of illness may be discharged from cardiologic follow-up 1 year after onset of illness. METHODS AND RESULTS To determine whether coronary artery dimensions in patients with Kawasaki disease whose vessels are classified as "normal" by Japanese Ministry of Health criteria have a distribution similar to expected population norms when adjusting for body surface area, we studied 125 patients during 4 intervals from onset of illness: (1) 10 days or less, (2) 2 weeks (11 to 21 days), (3) 6 weeks (22 days to 3 months), and (4) 1 year (4 months to 1.5 years). Using two-dimensional echocardiography, we measured the internal lumen diameter of the left main, proximal left anterior descending, and proximal right coronary arteries. Mean body surface area-adjusted dimensions of the proximal left anterior descending and right coronary arteries were significantly larger (P < .01) in patients with Kawasaki disease than those in subjects in all periods, except for a marginal difference at 6 weeks for the proximal right coronary artery (P = .02); for the left main coronary artery, this difference achieved statistical significance in the period of 10 days or less, with a trend at 2 weeks (P = .02). Among patients classified as having normal coronary arteries on all echocardiograms by the Japanese Ministry of Health criteria, 27% had at least 1 body surface area-adjusted coronary dimension more than 2 standard deviations above the expected mean. CONCLUSIONS Coronary artery dilation in Kawasaki disease is thus more prevalent than previously reported, highlighting the need for systematic long-term surveillance of this population.

Abstract
BACKGROUND Kawasaki disease (KD) is an acute vasculitis of infancy and early childhood for which there is currently no diagnostic test. The clinical presentation of KD may initially resemble other infectious diseases, including bacterial or viral meningitis. For this reason lumbar puncture (LP) is sometimes performed during the evaluation of these patients. To understand the range of cerebrospinal fluid (CSF) changes that may be associated with acute KD, a retrospective review of unselected KD patients from three pediatric centers was performed. METHODS Retrospective chart review was performed on KD patients evaluated during the first 10 days of illness who had an LP performed before the administration of intravenous gamma-globulin. RESULTS During the 6.5-year study period, 46 KD patients underwent LP as part of their clinical evaluation. Of these patients 18 (39.1%) had CSF pleocytosis, 1 (2.2%) had a CSF glucose <45 mg/dl and 8 (17.4%) had an elevated CSF protein. Of the patients with CSF pleocytosis, the median white blood cell count was 22.5 cells (range, 7 to 320 cells), with a median of 6.0% neutrophils (range, 0 to 79%) and 91.5% mononuclear cells (range, 11 to 100%). CONCLUSIONS In the present series approximately one-third of KD patients who underwent an LP had CSF pleocytosis with a mononuclear cell predominance. No patient had significant hypoglycorrhachia, and elevation of the CSF protein was uncommon. CSF abnormalities were similar between US and Japanese KD patients. The basis for the CSF pleocytosis in acute KD patients remains unknown.

Abstract
To construct a predictive instrument for developing coronary artery abnormalities in patients with acute Kawasaki disease treated with aspirin and intravenous gamma globulin within the first 10 days of illness, data available from a multicenter database of patients with acute Kawasaki disease were analyzed. A development data set (n = 212) was used to construct a sequential risk classification instrument based on easily measured baseline laboratory test results and temperature. The instrument was then validated in 3 test data sets (n = 192, 264, and 92, respectively). Risk factors used in the sequential classification instrument included baseline neutrophil and band counts, hemoglobin concentration, platelet count, and temperature on the day after infusion of intravenous gamma globulin. In the development data set, the instrument classified 123 of 212 patients (58%) as low risk; none developed coronary artery abnormalities. Among 89 patients classified as high risk, 3 of 36 female (8.3%) and 9 of 53 male patients (17.0%) developed coronary artery abnormalities. The instrument performed similarly in the 3 test data sets; no patient in any data set classified as low risk developed coronary artery abnormalities. This simple instrument allows the clinician to identify within 1 day of treatment low-risk children in whom extensive and frequent cardiac testing may be unnecessary, as well as high-risk children who require closer monitoring and may be candidates for additional therapies.

Abstract
BACKGROUND The outcome of infants who have transient seizures after open heart surgery has not been studied. Using the database of the Boston Circulatory Arrest Study involving 171 children with D-transposition of the great arteries, we explored the relationship between early postoperative clinical and EEG seizures and neurodevelopmental outcomes at ages 1 and 2 1/2 years. METHODS AND RESULTS At 1 year, children returned for developmental and neurological evaluations and MRI. Parent-completed developmental questionnaires were collected at 2 1/2 years of age. At 1 year, children with early postoperative seizures had lower Psychomotor Development Index (motor function) scores (clinical seizures: 12.9 mean difference [MD]; 95% confidence interval [CI], 2.2 to 23.6; P=.02; EEG seizures: 13.3 MD; 95% CI, 6.8 to 19.7; P<.001). Mental Developmental Index scores of children with clinical or EEG seizures were also lower, but the differences were not statistically significant. Infants with seizures were more likely to have an abnormal neurological examination (clinical seizures: 78% versus 31%; P=.008; EEG seizures: 58% versus 34%; P=.04). Children with EEG seizures were more likely to have MRI abnormalities (43% versus 13%, P=.002). At age 2 1/2, children with EEG seizures had lower scores in several areas of function. CONCLUSIONS In infants undergoing the arterial switch operation for correction of D-transposition of the great arteries, transient postoperative clinical and EEG seizures were associated with worse neurodevelopmental outcomes at ages 1 and 2 1/2 years as well as neurological and MRI abnormalities at 1 year of age. The occurrence of such seizures may provide an early sign of brain injury with neurological and developmental sequelae.

Abstract
OBJECTIVES In a randomized, single-center trial, we compared perioperative outcomes in infants undergoing cardiac operations after use of the alpha-stat versus pH-stat strategy during deep hypothermic cardiopulmonary bypass. METHODS Admission criteria included reparative cardiac surgery, age less than 9 months, birth weight 2.25 kg or more, and absence of associated congenital or acquired extracardiac disorders. RESULTS Among the 182 infants in the study, diagnoses included D-transposition of the great arteries (n = 92), tetralogy of Fallot (n = 50), tetralogy of Fallot with pulmonary atresia (n = 6), ventricular septal defect (n = 20), truncus arteriosus (n = 8), complete atrioventricular canal (n = 4), and total anomalous pulmonary venous return (n = 2). Ninety patients were assigned to alpha-stat and 92 to pH-stat strategy. Early death occurred in four infants (2%), all in the alpha-stat group (p = 0.058). Postoperative electroencephalographic seizures occurred in five of 57 patients (9%) assigned to alpha-stat and one of 59 patients (2%) assigned to pH-stat strategy (p = 0.11). Clinical seizures occurred in four infants in the alpha-stat group (4%) and two infants in the pH-stat group (2%) (p = 0.44). First electroencephalographic activity returned sooner among infants randomized to pH-stat strategy (p = 0.03). Within the homogeneous D-transposition subgroup, those assigned to pH-stat tended to have a higher cardiac index despite a lower requirement for inotropic agents; less frequent postoperative acidosis (p = 0.02) and hypotension (p = 0.05); and shorter duration of mechanical ventilation (p = 0.01) and intensive care unit stay (p = 0.01). CONCLUSIONS Use of the pH-stat strategy in infants undergoing deep hypothermic cardiopulmonary bypass was associated with lower postoperative morbidity, shorter recovery time to first electroencephalographic activity, and, in patients with D-transposition, shorter duration of intubation and intensive care unit stay. These data challenge the notion that alpha-stat management is a superior strategy for organ protection during reparative operations in infants using deep hypothermic cardiopulmonary bypass.

Abstract
OBJECTIVE To update recommendations issued by the American Heart Association last published in 1990 for the prevention of bacterial endocarditis in individuals at risk for this disease. PARTICIPANTS An ad hoc writing group appointed by the American Heart Association for their expertise in endocarditis and treatment with liaison members representing the American Dental Association, the Infectious Diseases Society of America, the American Academy of Pediatrics, and the American Society for Gastrointestinal Endoscopy. EVIDENCE The recommendations in this article reflect analyses of relevant literature regarding procedure-related endocarditis, in vitro susceptibility data of pathogens causing endocarditis, results of prophylactic studies in animal models of endocarditis, and retrospective analyses of human endocarditis cases in terms of antibiotic prophylaxis usage patterns and apparent prophylaxis failures. MEDLINE database searches from 1936 through 1996 were done using the root words endocarditis, bacteremia, and antibiotic prophylaxis. Recommendations in this document fall into evidence level III of the US Preventive Services Task Force categories of evidence. CONSENSUS PROCESS The recommendations were formulated by the writing group after specific therapeutic regimens were discussed. The consensus statement was subsequently reviewed by outside experts not affiliated with the writing group and by the Science Advisory and Coordinating Committee of the American Heart Association. These guidelines are meant to aid practitioners but are not intended as the standard of care or as a substitute for clinical judgment. CONCLUSIONS Major changes in the updated recommendations include the following: (1) emphasis that most cases of endocarditis are not attributable to an invasive procedure; (2) cardiac conditions are stratified into high-, moderate-, and negligible-risk categories based on potential outcome if endocarditis develops; (3) procedures that may cause bacteremia and for which prophylaxis is recommended are more clearly specified; (4) an algorithm was developed to more clearly define when prophylaxis is recommended for patients with mitral valve prolapse; (5) for oral or dental procedures the initial amoxicillin dose is reduced to 2 g, a follow-up antibiotic dose is no longer recommended, erythromycin is no longer recommended for penicillin-allergic individuals, but clindamycin and other alternatives are offered; and (6) for gastrointestinal or genitourinary procedures, the prophylactic regimens have been simplified. These changes were instituted to more clearly define when prophylaxis is or is not recommended, improve practitioner and patient compliance, reduce cost and potential gastrointestinal adverse effects, and approach more uniform worldwide recommendations.

Abstract
BACKGROUND The vascular injury and tissue damage after cardiopulmonary bypass (CPB) involves leukocyte-endothelial interactions mediated by cell adhesion molecules. This study was designed to determine the time course of soluble adhesion molecule levels after CPB in infants and children and to determine whether these levels correlated with preoperative variables, intraoperative bypass management, or postoperative course. METHODS AND RESULTS In 56 patients undergoing CPB (median age 1.0 year, range 2 days to 19 years), plasma concentrations of soluble E-, P-, and L-selection, soluble ICAM-1, and soluble VCAM-1 were measured using sandwich enzyme-linked immunosorbent assays at the following times: at induction of anesthesia, after 15 minutes of CPB, at the end of CPB, and 1, 6, 18, and 42 hours after CPB. Preoperative, intraoperative, and postoperative data were prospectively recorded. All soluble adhesion molecule levels fell markedly at the initiation of CPB as a result of a combination of dilution and bypass circuit uptake. The time course of soluble selectins (P, E, and L), normalized to end of bypass levels, all rose significantly (P<.001) in the initial 6 hours after CPB and then returned to end bypass levels at 42 hours. Soluble ICAM-1 and VCAM rose 63% and 89% in the first 6 hours and remained elevated throughout the 42 hours. Peak soluble P-selectin levels were associated with total support time (P=.04) and preoperative cyanosis (P=.003). Soluble L-selectin levels were inversely associated with longer total support time (P=.002), longer circulatory arrest time (P=.004), longer length of intubation (P=.0009), preoperative cyanosis (P=.002), and younger age at surgery (P=.01). CONCLUSIONS Soluble adhesion molecules have a characteristic time course in infants and children undergoing CPB. The soluble adhesion molecule levels after CPB change most significantly in patients with the highest potential for vascular injury: younger, cyanotic patients with longer pump times and longer postoperative courses. These data may be useful in the assessment of new therapies.

Abstract
BACKGROUND HDL cholesterol levels are known to be lower in smokers than in nonsmokers. Previous studies have demonstrated an association of decreased HDL cholesterol with passive smoking in children but have not adjusted for potential confounding factors. METHODS AND RESULTS In a cross-sectional, pilot-scale study, we examined the relationship of HDL cholesterol levels to passive smoking in children and adolescents referred to a tertiary hyperlipidemia clinic. Eligibility criteria included (1) first visit to a lipid clinic, (2) LDL cholesterol >95th percentile for age or HDL cholesterol <5th percentile, (3) age between 2 and 18 years, and (4) absence of secondary causes of hyperlipidemia. Sociodemographic information, diet record, medical history, and fasting lipid profiles were obtained. Of 109 eligible patients, 103 (94%) were studied. Twenty-seven percent came from households with cigarette smokers. HDL cholesterol levels were 38.7+/-1.2 mg/dL (mean+/-SEM) in passive smokers versus 43.6+/-1.2 mg/dL in children without smoke exposure (P=.005). Smoking exposure was not significantly associated with other lipid values. The effect of smoking on HDL cholesterol was minimally affected by potential confounders. In multivariate regression adjusting for body mass index, age, sex, exercise, and dietary fat intake, passive smoking remained a significant risk factor for decreased HDL cholesterol (P=.012). CONCLUSIONS Mean HDL cholesterol levels are lower in dyslipidemic children from households with smokers than in those without household smoke exposure. Passive smoking may worsen the risk profile for later atherosclerosis among high-risk young persons.

Abstract
OBJECTIVES The purpose of this study was to review a large, evolving, single-center experience with the Fontan operation and to determine risk factors influencing early and late outcome. METHODS The first 500 patients undergoing modifications of the Fontan operation at our institution were identified. Perioperative variables were recorded and a cross-sectional review of survivors was undertaken. RESULTS The incidence of early failure decreased from 27.1% in the first quartile of the experience to 7.5% in the last quartile. In a multivariate model, the following variables were associated with an increased probability of early failure: a mean preoperative pulmonary artery pressure of 19 mm Hg or more (p < 0.001), younger age at operation (p = 0.001), heterotaxy syndrome (p = 0.03), a right-sided tricuspid valve as the only systemic atrioventricular valve (p = 0.001), pulmonary artery distortion (p = 0.04), an atriopulmonary connection originating at the right atrial body or appendage (p = 0.001), the absence of a baffle fenestration (p = 0.002), and longer cardiopulmonary bypass time (p = 0.001). An increased probability of late failure was associated with the presence of a pacemaker before the Fontan operation (p < 0.001). A morphologically left ventricle with normally related great arteries or a single right ventricle (excluding heterotaxy syndrome and hypoplastic left heart syndrome) were associated with a decreased probability of late failure (p = 0.003). CONCLUSIONS These analyses indicate that early failure has declined over the study period and that this decline is related in part to procedural modifications. A continuing late hazard phase is associated with few patient-related variables and does not appear related to procedural variables.

Abstract
OBJECTIVES The purpose of this study was to describe the functional outcome of a large number of patients after modifications of the Fontan operation and to investigate perioperative risk factors that might influence late functional state. METHODS A comprehensive cross-sectional review of the first 500 patients undergoing a Fontan operation at our institution was undertaken. Those surviving with an intact Fontan circulation were reviewed by questionnaire to assess functional status and medication history. Medical records, chest roentgenograms, echocardiograms, cardiac catheterizations, and laboratory investigations were also reviewed to assess postoperative status. RESULTS Three hundred sixty-three long-term survivors with an intact Fontan circulation were identified during cross-sectional follow-up. Median age at operation was 5.0 years (range 0.4 to 31 years), and median follow-up was 5.4 years (range 1.7 to 20 years). Most patients (91.1%) were in New York Heart Association class I or II. In a multivariate model, poor (class III or IV) functional state was associated with longer duration of follow-up (p < 0.001), a prior atrial septectomy (p = 0.03), and a prior main pulmonary artery-ascending aorta anastomosis (p = 0.05). CONCLUSIONS A poor functional outcome is uncommon after the Fontan operation but becomes more frequent with increasing duration of follow-up.

PARTICIPANTS An ad hoc writing group appointed by the American Heart Association for their expertise in endocarditis and treatment with liaison members representing the American Dental Association, the Infectious Diseases Society of America, the American Academy of Pediatrics, and the American Society for Gastrointestinal Endoscopy. EVIDENCE The recommendations in this article reflect analyses of relevant literature regarding procedure-related endocarditis, in vitro susceptibility data of pathogens causing endocarditis, results of prophylactic studies in animal models of endocarditis, and retrospective analyses of human endocarditis cases in terms of antibiotic prophylaxis usage patterns and apparent prophylaxis failures. MEDLINE database searches from 1936 through 1996 were done using the root words endocarditis, bacteremia, and antibiotic prophylaxis. Recommendations in this document fall into evidence level III of the US Preventive Services Task Force categories of evidence. CONSENSUS PROCESS The recommendations were formulated by the writing group after specific therapeutic regimens were discussed. The consensus statement was subsequently reviewed by outside experts not affiliated with the writing group and by the Science Advisory and Coordinating Committee of the American Heart Association. These guidelines are meant to aid practitioners but are not intended as the standard of care or as a substitute for clinical judgment. CONCLUSIONS Major changes in the updated recommendations include the following: (1) emphasis that most cases of endocarditis are not attributable to an invasive procedure; (2) cardiac conditions are stratified into high-, moderate-, and negligible-risk categories based on potential outcome if endocarditis develops; (3) procedures that may cause bacteremia and for which prophylaxis is recommended are more clearly specified; (4) an algorithm was developed to more clearly define when prophylaxis is recommended for patients with mitral valve prolapse; (5) for oral or dental procedures the initial amoxicillin dose is reduced to 2 g, a follow-up antibiotic dose is no longer recommended, erythromycin is no longer recommended for penicillin-allergic individuals, but clindamycin and other alternatives are offered; and (6) for gastrointestinal or genitourinary procedures, the prophylactic regimens have been simplified. These changes were instituted to more clearly define when prophylaxis is or is not recommended, improve practitioner and patient compliance, reduce cost and potential gastrointestinal adverse effects, and approach more uniform worldwide recommendations.

Abstract
A randomized clinical trial was conducted to compare the early development of children with d-transposition of the great arteries (N = 171) repaired by an arterial switch operation that used either predominantly total circulatory arrest or predominantly continuous low-flow cardiopulmonary bypass. The children assigned to the circulatory arrest group scored lower than those assigned to low-flow bypass on the Bayley Scales of Infant Development at 1 year of age. Responses to parental questionnaires completed when the children were 2.5 years old indicated that the children in the circulatory arrest group, especially those with a ventricular septal defect, also manifested poorer expressive language and were considered to display more internalizing and externalizing problem behaviors. The use of circulatory arrest to protect vital organs during open heart surgery might place children at increased risk of early developmental difficulties, especially in the domains of motor and language function.

Abstract
Many infants with cardiac anomalies undergo repair early in life. Both commonly used support techniques, deep hypothermic circulatory arrest (DHCA) and low-flow cardiopulmonary bypass (LFB), may be associated with adverse neurological outcomes, including seizures. In a single center study, 171 infants undergoing correction for D-transposition of the great arteries were randomized to one of these support techniques. Incidence and onset times of EEG seizures during continuous EEG-video monitoring in the first 48 h postoperatively and clinical seizures in the first postoperative week were compared. EEG seizures were characterized by time, duration, and localization of onset. Incidence of EEG seizures (20%) was more than 3 times that of clinical seizures (6%). Most infants with EEG seizures had multiple seizures beginning between 13 and 36 h postoperatively. Durations ranged from 6 s to 980 min. Onset of EEG seizures occurred most commonly in frontal and central regions. Factors associated with EEG seizures included randomization to DHCA, longer duration of circulatory arrest, and diagnosis of VSD. In this study EEG seizures were common following this type of cardiac surgery, illustrating the importance of EEG monitoring in detecting seizures. This data adds insight into mechanisms of seizures in infants undergoing cardiac surgery.
