Fetal Echocardiographic Variables Associated with Pre-Surgical Mortality in Truncus Arteriosus: A Pilot Study. Pediatr Cardiol 2023:10.1007/s00246-023-03099-9. [PMID: 36854855 DOI: 10.1007/s00246-023-03099-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/18/2022] [Accepted: 01/10/2023] [Indexed: 03/02/2023]
Abstract
Truncus arteriosus (TA) is a rare congenital heart defect that can be prenatally detected by fetal echocardiography. However, prognostication and prenatal counseling focus primarily on surgical outcomes due to limited fetal and neonatal pre-surgical mortality data. We aimed to describe the incidence and identify predictors of pre-surgical mortality in prenatally detected TA. This two-center, retrospective cohort study included fetuses diagnosed with TA between 01/2010 and 04/2020. The primary outcome was pre-surgical mortality, defined by fetal or neonatal pre-surgical death or primary listing for transplantation prior to discharge. Univariable regression modeling, Chi-square tests, and t tests assessed for associations between prenatal clinical, demographic, and fetal echocardiographic (fetal-echo) variables and pre-surgical mortality. Of 23 pregnancies with prenatal diagnosis of TA, 4 (17%) were terminated. Of the remaining 19, pre-surgical mortality occurred in 4 (26%), including 2 (11%) fetal deaths and 2 (11%) neonatal pre-surgical deaths. No transplantation listings. Of liveborn fetuses (n = 17), 15 (88%) underwent a neonatal surgery, and 1 (6%) required ECMO. As compared to the survivors, the pre-surgical mortality group had a higher likelihood of having left ventricular dysfunction (0% vs. 40%; p = 0.01), right ventricular dysfunction (0% vs. 60%; p = 0.002), cardiovascular profile score < 7 (0% vs. 40%; p = 0.01), skin edema (0% vs. 40%; p = 0.01), and abnormal umbilical venous (UV) Doppler (0% vs. 60%; p = 0.002). The presence of truncal valve regurgitation or stenosis neared significance. In this cohort with prenatally diagnosed TA, there is significant pre-surgical mortality, including fetal death and neonatal pre-surgical death. Termination rate is also high. Fetal-echo variables associated with pre-surgical mortality in this cohort include ventricular dysfunction, low CVP, skin edema, and abnormal UV Doppler. Knowledge about prenatal risk factors for pre-surgical mortality may guide parental counseling and postnatal planning in prenatally diagnosed TA.

Abstract
BACKGROUND Preterm birth and congenital heart defects are two major causes of neonatal and infant mortality. However, the relationship between them has not yet been fully clarified. OBJECTIVE To determine the prevalence and spectrum of congenital heart defects in preterms, the specific associations between categories of congenital heart defects and preterm birth and to establish the influence on outcomes. METHODS Observational, case-control analysis that included 448 live births with congenital heart defects born between 2003 and 2017. Preterm with congenital heart defects were the case subjects and term neonates with congenital heart defects the control subjects. RESULTS Of the newborns with congenital heart defects, 23% were preterm. The odds of congenital heart defects in preterm were twofold higher than for term neonates (p<0.0001), even when considering only those with severe congenital heart defects (p=0.0002). The odds in preterm were 9.2-fold higher for abnormalities of the atria and atrial septum (p<0.0001) and two-fold higher for abnormalities of the ventricles and ventricular septum (p<0.0001) compared with term neonates. The neonatal mortality rate in the preterm group was not statistically different from that of the term group with congenital heart defects (p=0.799) or severe congenital heart defects (p=0.554). CONCLUSION Preterm have more than twice as many congenital heart defects as term neonates. Although the etiology of prematurity between infants with congenital heart defects is still uncertain, our findings highlight a possible relationship between prematurity and congenital heart defects.

Abstract
Outcomes for patients with neonatal heart disease are affected by numerous noncardiac and genetic factors. These can include neonatal concerns, such as prematurity and low birth weight, and congenital anomalies, such as airway, pulmonary, gastrointestinal, and genitourinary anomalies, and genetic syndromes. This section will serve as a summary of these issues and how they may affect the evaluation and management of a neonate with heart disease. These noncardiac factors are heavily influenced by conditions common to neonatologists, making a strong argument for multidisciplinary care with neonatologists, cardiologists, surgeons, anesthesiologists, and cardiovascular intensivists. Through this section and this project, we aim to facilitate a comprehensive approach to the care of neonates with congenital heart disease.

Abstract
Congenital heart disease (CHD) is the most commonly reported birth defect in newborns. Neonates with CHD are more likely to be born prematurely, and a higher proportion of preterm neonates have CHD than their term counterparts. The implications of preterm birth on the cardiac and noncardiac organ systems are vast and require special management considerations. The feasibility of surgical interventions in preterm neonates is frequently limited by patient size and delicacy of immature cardiac tissues. Thus, special care must be taken when considering the appropriate timing and type of cardiac intervention. Despite improvements in neonatal cardiac surgical outcomes, preterm and early term gestational ages and low birthweight remain important risk factors for in-hospital mortality. Understanding the risks of early delivery of neonates with prenatally diagnosed CHD may help guide perioperative management in neonates who are born preterm. In this review, we will describe the risks and benefits of early delivery, postnatal cardiac and noncardiac evaluation and management, surgical considerations, overall outcomes, and future directions regarding optimization of perinatal evaluation and management of fetuses and preterm and early term neonates with CHD.

Abstract
BACKGROUND The frequency, mortality, and morbidity of very low birth weight (VLBW) infants with congenital heart disease (CHD) in Asian countries are limited. In addition, little is known about the risk factors of death in these infants. METHODS A retrospective, multicenter cohort study was conducted. VLBW infants with CHD born between 2006 and 2010, and followed to 5 years of age, were included in the analysis. Multiple logistic regression analysis was performed to identify the risk factors of death. RESULTS Among 3247 VLBW infants, 126 various CHDs (3.9 %) were identified. The most common lesions were ventricular septal defect, tetralogy of Fallot (TOF), and coarctation of the aorta/interrupted aortic arch, in that order. The proportions of left-sided and right-sided outflow obstruction (TOF, pulmonary stenosis) were 15.1 % and 15.9 %, respectively. Trisomy 18 and trisomy 13 were present in 32 (25.4 %) of 126 VLBW infants with CHD. Nine patients were lost to follow-up. Overall, 45 patients (35.7 %) died up to 5 years of age. Serious CHD [odds ratio (OR), 19.2; 95 % confidential interval (CI), 3.94-93.11; p < 0.0001], sepsis (OR, 42.3; 95 % CI, 5.39-332.22; p < 0.0001), chromosomal /named anomalies (OR, 7.50; 95%CI, 2.09-26.94; p = 0.001), and no-invasive treatments (OR, 9.89; 95%CI, 2.28-42.91; p = 0.001) were associated with death. On excluding chromosomal anomalies, twelve of 71 patients (16.9 %) died, and only sepsis (OR, 35.5, 95%CI, 2.63-477.1; p = 0.0008) was an independent risk factor. CONCLUSIONS Trisomy 18 and trisomy 13 of chromosomal anomalies are frequently associated with VLBW infants with CHD. The mortality of VLBW infants with CHD is high, even when chromosomal anomalies are excluded. Sepsis has a significant impact on death in VLBW infants with CHD.

Abstract
AIM To compare in-hospital mortality and rates of necrotising enterocolitis (NEC), sepsis, IVH and length of invasive respiratory support in preterm infants <36 weeks' gestation with congenital heart disease (CHD) to matched preterm infants without CHD in a single London centre over 13-year period. METHODS Single-centre retrospective case-control study over the 13-year period from May 2004 to May 2017. RESULTS Two hundred forty-seven preterm infants with CHD were matched to 494 infants without CHD. Patients with CHD had a significantly increased risk of in-hospital mortality compared to controls (OR 7.39 (95% CI 4.37-12.5); p < 0.001). Preterm infants with CHD had a higher risk of NEC (OR 2.42 (95% CI 1.32-4.45); p = 0.005), sepsis (OR 1.68 (95% CI 1.23-2.28); p = 0.001) and invasive respiratory support ≥28 days (OR 2.34 (95% CI 1.19-4.58); p = 0.017). Risk of IVH was lower in preterm infants with CHD (OR 0.22 (95% CI 0.11-0.42); p = 0.0001). CONCLUSION Preterm birth with CHD is associated with a higher risk of in-hospital mortality, NEC, sepsis and prolonged invasive respiratory support, but a lower risk of IVH compared to matched controls. In-hospital mortality remains high in moderate-to-late preterm infants with CHD.

Abstract
OBJECTIVE To investigate the trends of 1-year mortality and neonatal morbidities in preterm infants with serious congenital heart disease (CHD). STUDY DESIGN This cohort study used a population-based administrative dataset of all liveborn infants of 26-36 weeks gestational age with serious CHD born in California between 2011 and 2017. We assessed 1-year mortality and major neonatal morbidities (ie, retinopathy of prematurity, bronchopulmonary dysplasia, necrotizing enterocolitis, intraventricular hemorrhage grade >2, and periventricular leukomalacia) across the study period and compared these outcomes with those in infants without CHD. RESULTS We identified 1921 preterm infants with serious CHD. The relative risk (RR) of death decreased by 10.6% for each year of the study period (RR, 0.89; 95% CI, 0.84-0.95), and the RR of major neonatal morbidity increased by 8.3% for each year (RR, 1.08; 95% CI, 1.02-1.15). Compared with preterm neonates without any CHD (n = 234 522), the adjusted risk difference (ARD) for mortality was highest at 32 weeks of gestational age (9.7%; 95% CI, 8.3%-11.2%), that for major neonatal morbidity was highest at 28 weeks (21.9%; 95% CI, 17.0%-26.9%), and that for the combined outcome was highest at 30 weeks (26.7%; 95% CI, 23.3%-30.1%). CONCLUSIONS Mortality in preterm neonates with serious CHD decreased over the last decade, whereas major neonatal morbidities increased. Preterm infants with a gestational age of 28-32 weeks have the highest mortality or morbidity compared with their peers without CHD. These results support the need for specialized and focused medical neonatal care in preterm neonates with serious CHD.

Abstract
OBJECTIVES Very low birthweight (<1500 g, VLBW) infants with severe congenital heart defect (CHD) are at increased risk for perinatal and operative mortality. This study aims to describe morbidity, long-term mortality and neuro-developmental outcome in early childhood in VLBW infants who received cardiac surgery for severe CHD within 1 year after birth. METHODS Monocentric observational study on VLBW infants with severe CHD born between 2008 and 2017. Neurodevelopmental impairment at 2 years corrected age was defined as cognitive deficit, cerebral palsy or major neurosensory deficit. RESULTS A total of 24 patients were included. Twenty-one (87.5%) infants underwent cardiac surgery with hypothermia during cardiopulmonary bypass (median temperature 30.3°C, interquartile range 27.0-32.0°C) at a median age of 96 (40-188) days. Seven (29.2%, 95% confidence interval 14.9-49.2%) patients died within the first year after cardiac surgery. Survival rates decreased with increasing STAT mortality category of the surgical procedure. Neurodevelopmental impairment at 2 years of corrected age was found in 9 out of 17 (52.9%) surviving infants, with 8 infants (47.1%) presenting with a cognitive deficit or delay and 4 infants (23.5%) being diagnosed with cerebral palsy. Survival without neuro-developmental impairment was 29.2% (n = 7, 95% confidence interval 14.9-49.2%) in the entire study cohort. Eighty percent of the newborns with dextro-transposition of the great arteries, but no patient with univentricular anatomy, survived without neuro-developmental impairment. CONCLUSIONS Individual VLBW infants with severe CHD may develop well despite the high combined risk for adverse outcomes. The type of cardiac malformation may affect early- and long-term outcomes.

Abstract
OBJECTIVE To compare outcomes between low birth weight (LBW; <2.5 kg) and standard birth weight neonates undergoing cardiac surgery. STUDY DESIGN A single-center retrospective study of neonates undergoing cardiac surgery with cardiopulmonary bypass from 2012 to 2018. LBW neonates were 1:2 propensity score-matched to standard birth weight neonates (n = 93 to n = 186) using clinical characteristics. The primary and secondary outcomes were survival to hospital discharge and postoperative complications, respectively. After matching, regression analyses were conducted to compare outcomes. RESULTS The LBW group had a higher proportion of premature neonates than the standard birth weight group (60% vs 8%; P < .01) and were less likely to survive to hospital discharge (88% vs 95%; OR, 0.39; 95% CI, 0.15-0.97). There was no difference in unplanned cardiac reoperations or catheter-based interventions, cardiac arrest, extracorporeal membrane oxygenation, infection, and end-organ complications between the groups. Among LBW infants, survival was improved at weight >2 kg. CONCLUSIONS LBW is a risk factor for decreased survival. LBW neonates weighing >2 kg have survival comparable to those weighing >2.5 kg.

Abstract
Background: Compared with those born at term gestation, infants with complex congenital heart defects (CCHD) who were delivered before 37 weeks gestational age and received neonatal open-heart surgery (OHS) have poorer neurodevelopmental outcomes in early childhood. We aimed to describe the growth, disability, functional, and neurodevelopmental outcomes in early childhood of preterm infants with CCHD after neonatal OHS. Prediction models were evaluated at various timepoints during hospitalization which could be useful in the management of these infants. Study Design: We studied all preterm infants with CCHD who received OHS within 6 weeks of corrected age between 1996 and 2016. The Western Canadian Complex Pediatric Therapies Follow-up Program completed multidisciplinary comprehensive neurodevelopmental assessments at 2-year corrected age at the referral-site follow-up clinics. We collected demographic and acute-care clinical data, standardized age-appropriate outcome measures including physical growth with calculated z-scores; disabilities including cerebral palsy, visual impairment, permanent hearing loss; adaptive function (Adaptive Behavior Assessment System-II); and cognitive, language, and motor skills (Bayley Scales of Infant and Toddler Development-III). Multiple variable logistic or linear regressions determined predictors displayed as Odds Ratio (OR) or Effect Size (ES) with 95% confidence intervals. Results: Of 115 preterm infants (34 ± 2 weeks gestation, 2,339 ± 637 g, 64% males) with CCHD and OHS, there were 11(10%) deaths before first discharge and 21(18%) deaths by 2-years. Seven (6%) neonates had cerebral injuries, 7 had necrotizing enterocolitis; none had retinopathy of prematurity. Among 94 survivors, 9% had cerebral palsy and 6% had permanent hearing loss, with worse outcomes in those with syndromic diagnoses. Significant predictors of mortality included birth weight z-score [OR 0.28(0.11,0.72), P = 0.008], single-ventricle anatomy [OR 5.92(1.31,26.80), P = 0.021], post-operative ventilation days [OR 1.06(1.02,1.09), P = 0.007], and cardiopulmonary resuscitation [OR 11.58 (1.97,68.24), P = 0.007]; for adverse functional outcome in those without syndromic diagnoses, birth weight 2,000-2,499 g [ES -11.60(-18.67, -4.53), P = 0.002], post-conceptual age [ES -0.11(-0.22,0.00), P = 0.044], post-operative lowest pH [ES 6.75(1.25,12.25), P = 0.017], and sepsis [ES -9.70(-17.74, -1.66), P = 0.050]. Conclusions: Our findings suggest preterm neonates with CCHD and early OHS had significant mortality and morbidity at 2-years and were at risk for cerebral palsy and adverse neurodevelopment. This information may be important for management, parental counseling and the decision-making process.

Abstract
Abstract
Objectives
To analyze pregnancy management and postnatal follow-up in monochorionic monoamniotic (MCMA) pregnancies complicated by a congenital heart defect (CHD) in one twin and to compare the results with current recommendations concerning time and mode of delivery in MCMA pregnancies.
Cases presentation
Perinatal medical records of five pairs of monoamniotic twins referred to Fetal Cardiology Department were analyzed. 5 out of 23 MCMA pregnancies (21.7%) were complicated by CHD in one fetus. Cesarean section (CS) was performed between 32 and 35 weeks of gestation (WoG). 9 out of 10 neonates had respiratory failure, including all patients with CHD. Twins without congenital abnormalities spent median 21 days (range 10–40 days) in neonatal units. Patients with CHD were transferred to cardiology departments on average 6th day of life. All were operated on later than term-born neonates, 4 out of 5 required stage surgery and their median stay in the hospital was 75 days (range 48–106 days).
Conclusions
According to current recommendations, delivery in MCMA pregnancies should be scheduled at 32–34 weeks. In cases complicated by CHD in one twin, such early delivery complicates surgical treatment and may affect the final outcome. Low body weight and respiratory disorders increase the risk of complications in the perioperative period and prolong hospitalization.

Abstract
OBJECTIVE To examine state-wide population trends in preterm delivery of children with critical congenital heart disease (CHD) over an 18-year period. We hypothesized that, coincident with early advancements in prenatal diagnosis, preterm delivery initially increased compared with the general population, and more recently has decreased. STUDY DESIGN Data from the Texas Public Use Data File 1999-2016 was used to evaluate annual percent preterm delivery (<37 weeks) in critical CHD (diagnoses requiring intervention at <1 year of age). We first evaluated for pattern change over time using joinpoint segmented regression. Trends in preterm delivery were then compared with all Texas livebirths. We then compared trends examining sociodemographic covariates including race/ethnicity, sex, and neighborhood poverty levels. RESULTS Of 7146 births with critical CHD, 1339 (18.7%) were delivered preterm. The rate of preterm birth increased from 1999 to 2004 (a mean increase of 1.69% per year) then decreased between 2005 and 2016 (a mean decrease of -0.41% per year). This represented a faster increase and then a similar decrease to that noted in the general population. Although the greatest proportion of preterm births occurred in newborns of Hispanic ethnicity and non-Hispanic black race, newborns with higher neighborhood poverty level had the most rapidly increasing rate of preterm delivery in the first era, and only a plateau rather than decrease in the latter era. CONCLUSIONS Rates of preterm birth for newborns with critical CHD in Texas first were increasing rapidly, then have been decreasing since 2005.

Abstract
There are limited data on the relation between congenital heart disease (CHD) and preterm birth (PTB). We aimed to estimate the risk of PTB in newborns with CHD, to study associations and risk factors (modifiable and non-modifiable) as well as investigate postnatal outcomes. This was a retrospective cohort study of 336 pregnancies diagnosed with CHD between 2011 and 2016. Groups consisted of those delivered at or after 37 weeks, and those who delivered prior to 37 weeks. Collected data included maternal and fetal characteristics as well postnatal outcomes. Complete data were obtained from 237 singleton pregnancies. The overall proportion of PTB was 23.2% for all CHD, of which 38.2% were spontaneous PTB which was almost unchanged after excluding extracardiac anomalies and pathogenic chromosomal abnormalities. Significant non-modifiable risk factors were pregnancy-related HTN disorders (P < 0.001), fetal growth restriction (P = 0.01), and pathogenic chromosomal abnormalities (P = 0.046). Significant PTB modifiable risk factors included prenatal marijuana use (P = 0.01). Pregnancies delivered at 37-38 weeks had significantly more newborns with birthweight < 2500 g (P < 0.001), required more pre-operative NICU support including intubation (P = 0.049), vasopressors (P = 0.04), prostaglandins (P = 0.003), antibiotics (P = 0.01), and had longer hospital stay (P = 0.001) than those delivered at ≥ 39 weeks. Prenatally diagnosed pregnancies with CHD had higher PTB rate compared to the general population, with spontaneous PTB comprising 38.2% of these preterm deliveries. Most PTB risk factors were non-modifiable, however, significant modifiable factors included marijuana use in pregnancy. Outcomes were favorable in neonates delivered at or beyond 39 weeks.

Abstract
Congenital heart defects are the most common birth anomaly affecting approximately 1% of births. With improved survival in this population, there is enhanced ability to assess long-term morbidities including neurodevelopment. There is a wide range of congenital heart defects, from those with minimal physiologic consequence that do not require medical or surgical intervention, to complex structural anomalies requiring highly specialized medical management and intricate surgical repair or palliation. The impact of congenital heart disease on neurodevelopment is multifactorial. Susceptibility for adverse neurodevelopment increases with advancing severity of the defect with initial risk factors originating during gestation. Complex structural heart anomalies may pre-dispose the fetus to abnormal circulatory patterns in utero that ultimately impact delivery of oxygen rich blood to the fetal brain. Thus, the brain of a neonate born with complex congenital heart disease may be particularly vulnerable from the outset. That vulnerability is compounded during the newborn period and through childhood, as this population endures a myriad of medical and surgical interventions. For each individual patient, these factors are likely cumulative and synergistic with progression from fetal life through childhood. This review discusses the spectrum of risk factors that may impact neurodevelopment in children with congenital heart disease, describes current recommendations and practices for neurodevelopmental follow-up of children with congenital heart disease and reviews important neurodevelopmental trends in this high risk population.

Necrotizing Enterocolitis in Infants with Hypoplastic Left Heart Syndrome Following Stage 1 Palliation or Heart Transplant. Pediatr Cardiol 2018; 39:774-785.

Abstract
Previous studies of necrotizing enterocolitis (NEC) among infants with hypoplastic left heart syndrome (HLHS) were conducted in single centers or had small sample sizes. This study aimed to determine the mortality rate and the risk factors for NEC among infants with HLHS who were discharged over a 10-year period (2004-2013) from 41 Pediatric Health Information System affiliated children's hospitals. Either stage 1 palliation and/or heart transplant were completed prior to patient's death or hospital discharge. We compared the characteristics of infants with HLHS who did not develop NEC and those who developed medical or surgical NEC and of patients who had medical vs. surgical NEC. The primary outcome was mortality over time and by birth weight category (low birth weight [LBW], birth weight < 2500 vs. ≥ 2500 g). Multivariable analyses were performed to identify the risk factors for developing NEC and for mortality among infants with HLHS. The study evaluated 5720 infants with HLHS including 349 patients (6.1%) with medical or surgical NEC. Fifty-two patients (0.9%) required laparotomy or percutaneous abdominal drainage. On univariable analysis, the overall mortality rate for infants who developed NEC was significantly higher than infants who did not develop NEC (23.5 vs. 13.9%, P < 0.001). On multivariable analysis, neither medical nor surgical NEC was a significant predictor of mortality in the study population. LBW infants were at higher risk for mortality in both the univariable and the multivariable models. Nevertheless, LBW did not significantly predispose infants with HLHS to develop NEC. Our results provide a national benchmark incidence of NEC, its risk factors, and outcomes among a large cohort of infants with HLHS and establish that NEC is not a significant risk factor for mortality in this population.

Abstract
Background: Studies on the influence of congenital heart disease (CHD) on neonates with necrotizing enterocolitis (NEC) have produced varied results. We therefore examined the influence of CHD on NEC outcomes. Methods: We carried out a retrospective single-center study including infants with confirmed NEC, treated between 2004 and 2017. We excluded patients with isolated patent ductus arteriosus or pulmonary hypertension (n = 45) and compared outcomes of patients with hemodynamically relevant CHD (n = 38) and those without CHD (n = 91). Results: Patients with CHD were more mature than those without CHD [gestational age, median, 95% confidence interval (CI95), 37.1, 34.5-37.2w, vs. 32.6, 31.9-33.3w; P < 0.01]. The presence of CHD did not influence the frequencies of severe disease (overall 21% Bell stage III), nor surgical interventions (overall 30%), the occurrence of intestinal complications (overall 13%), nor the duration of hospitalization (overall 38 days in survivors). The overall mortality as well as NEC-related mortality was increased with the presence of CHD, being 50% (19 out of 38) and 13% (5 out of 38), respectively, when compared to patients without CHD, being 8% (7 out of 91) and 3% (3 out of 91). The presence of CHD and of advanced NEC stage III were independent predictors of NEC-associated fatalities with multivariable odds ratios (CI95) of 7.0, 1.3-39.5 for CHD, and of 3.4, 1.6-7.5 for stage III disease. Conclusions: While some outcome parameters in neonates with NEC remained unaffected by the presence of CHD, the mortality risk for patients with CHD was seven times higher than without CHD.

Abstract
BACKGROUND A substantial proportion of infants born with tetralogy of Fallot (TOF) die in infancy. A better understanding of the heterogeneity associated with TOF, including extracardiac malformations and chromosomal anomalies is vital to stratifying risk and optimizing outcomes during infancy. METHODS Using the North Carolina Birth Defects Monitoring Program, infants diagnosed with TOF and born between 2003 and 2012 were included. Kaplan-Meier survival curves were used to estimate cumulative 1-year mortality, stratified by the presence of concomitant birth defects (BDs) and chromosomal anomalies. Multivariable logistic regression was used to estimate the direct effect of each concomitant BD, after adjusting for all others. RESULTS A total of 496 infants with TOF were included, and 15% (n = 76) died. The number of concomitant BD systems was significantly associated with the risk of death at 1-year, p < 0.0001. Specifically, the risk of mortality was 8% among infants with TOF with or without additional cardiac defects, 16% among infants with TOF and 1 extracardiac BD system, 19% among infants with 2 extracardiac BD systems, and 39% among infants with ≥ 3 extracardiac BD systems. After adjustment, concomitant eye and gastrointestinal defects were significantly associated increased with 1-year mortality, odds ratio 2.83 (95% confidence interval, 1.08-7.32) and odds ratio 4.43 (95% confidence interval, 1.57, 12.45), respectively. Infants with trisomy 13 or trisomy 18 were also significantly more likely to die, p < 0.0001. CONCLUSION Both concomitant BDs and genetic anomalies increase the risk of mortality among infants with TOF. Future studies are needed to identify the underlying genetic and socioeconomic risk factors for high-risk TOF infants. Birth Defects Research 109:1154-1165, 2017. © 2017 Wiley Periodicals, Inc.

Impact of preterm birth on infant mortality for newborns with congenital heart defects: The EPICARD population-based cohort study. BMC Pediatr 2017; 17:124.

Abstract
Background Congenital heart defects (CHD) and preterm birth (PTB) are major causes of infant mortality. However, limited data exist on risk of mortality associated with PTB for newborns with CHD. Our objective was to assess impact of PTB on risk of infant mortality for newborns with CHD, while taking into account the role of associated anomalies and other potentially confounding factors. Methods We used data on 2172 live births from a prospective population-based cohort study of CHD (the EPICARD Study) and compared neonatal, post-neonatal and overall infant mortality for infants born at <32, 32–34 and 35–36 weeks vs. those born at term (37–41 weeks). Results Preterm newborns had a 3.8-fold higher risk of infant death (17.9%) than term newborns (4.7%), RR 3.8, 95%CI 2.7–5.2; the risk associated with PTB was more than four-fold higher for neonatal (RR 4.3, 95% CI 2.9–6.6) and three-fold higher for post-neonatal deaths (RR 3.0, 95% CI 1.7–5.2). Survival analysis showed that newborns <35 weeks had a higher risk of mortality, which decreased but persisted after exclusion of associated anomalies and adjustment for potential confounders. Conclusions Preterm birth is associated with an approximately four-fold higher risk of infant mortality for newborns with CHD. This excess risk appears to be mostly limited to newborns <35 weeks of gestation and is disproportionately due to early deaths.

Abstract
OBJECTIVE To determine the birth prevalence of congenital heart defects (CHDs) across the spectrum of common defects in very/extremely premature infants and to compare mortality rates between premature infants with and without CHDs. STUDY DESIGN The Kids' Inpatient Databases (2003-2012) were used to estimate the birth prevalence of CHDs (excluding patent ductus arteriosus) in very/extremely premature infants born between 25 and 32 weeks' gestational age. Birth prevalence was compared with term infants for a subset of "severe" defects expected to be near universally diagnosed in the neonatal period. Weighted multivariable logistic regression was used to calculate aORs of mortality comparing very and extremely premature infants with vs without CHDs. RESULTS We identified 249 011 very/extremely premature infants, including 28 806 with CHDs. The overall birth prevalence of CHDs was 116 per 1000 very/extremely premature births. Severe CHDs had significantly higher birth prevalence in very/extremely premature infants when compared with term infants (7.4 per 1000 very/premature births vs 1.5 per 1000 term births; P < .001). Very/extremely premature infants with severe CHDs had an overall 26.3% in-hospital mortality and a 7.5-fold increased adjusted odds of death compared with those without CHDs. Mortality varied widely by defect in very/extremely premature infants, ranging from 12% for interrupted aortic arch to 67% for truncus arteriosus. CONCLUSIONS Given the increased birth prevalence of severe CHDs in very/extremely premature infants, and significantly higher mortality, there is justification for intensive interventions aimed at decreasing the likelihood of premature delivery for patients where CHD is diagnosed in utero.

Abstract
For premature infants with congenital heart disease (CHD), it may be unclear when the burdens of treatment outweigh potential benefits. Parents may thus have to choose between comfort care at birth and medical stabilization until surgical repair is feasible. Better defined outcome data, including risk factors for mortality, are needed to counsel expectant parents who are considering intensive care for premature infants with CHD. We sought to evaluate outcomes in this population to inform expectant parents considering intensive versus palliative care at birth. We performed a retrospective cohort study of infants born <34 weeks who received intensive care with critical or moderately severe CHD predicted to require surgery in the neonatal period or the first 6 months of life. 46 % of 54 infants survived. Among non-survivors, 74 % died prior to surgery (median age 24 days). Of the infants that underwent surgery, 75 % survived. Survival was lower among infants <32 weeks gestational age (GA) (p = 0.013), with birth weight (BW) <1500 g (p = 0.011), or with extra-cardiac anomalies (ECA) (p = 0.015). GA and ECA remained significant risk factors for mortality in multiple logistic regression analysis. In summary, GA < 32 weeks, BW < 1500 g, and ECA are determinable prenatally and were significant risk factors for mortality. The majority of infants who survived to cardiac intervention survived neonatal hospitalization, whereas most of the infants who died did so prior to surgery. For some expectant parents, this early declaration of mortality may support a trial of intensive care while avoiding burdensome interventions.

Abstract
BACKGROUND There is no agreement of the influence of patent ductus arteriosus (PDA) on outcomes in patients with necrotizing enterocolitis (NEC). In this study, we assessed the influence of PDA on NEC outcomes. METHODS A retrospective study of 131 infants with established NEC was performed. Outcomes (death, disease severity, need for surgery, hospitalization duration), as well as multiple clinical parameters were compared between NEC patients with no congenital heart disease (n=102) and those with isolated PDA (n=29). Univariate, multivariate and stepwise logistic regression analyses were performed. RESULTS Birth weight and gestational age were significantly lower in patients with PDA [median (95% CI): 1120 g (1009-1562 g), 28.4 wk (27.8-30.5 wk)] than in those without PDA [median (95% CI): 1580 g (1593-1905 g), 32.4 wk (31.8-33.5 wk); P<0.05]. The risk of NEC-attributable fatality was higher in NEC patients with PDA (35%) than in NEC patients without PDA (14%)[univariate odds ratio (OR)=3.3, 95% CI: 1.8-8.6, P<0.05; multivariate OR=2.4, 95% CI: 0.82-2.39, P=0.111]. Significant independent predictors for non-survival within the entire cohort were advanced disease severity stage III (OR=27.9, 95% CI: 7.4-105, P<0.001) and birth weight below 1100 g (OR=5.7, 95% CI: 1.7-19.4, P<0.01). CONCLUSIONS In patients with NEC, the presence of PDA is associated with an increased risk of death. However, when important differences between the two study groups are controlled, only birth weight and disease severity may independently predict mortality.

The association of congenital heart disease with necrotizing enterocolitis in preterm infants: a birth cohort study. J Perinatol 2015; 35:949-53.

Abstract
OBJECTIVE To test the hypothesis that congenital heart disease (CHD) in preterm infants with severe CHD (cyanotic or left-sided obstructive lesions, or congestive heart failure) is independently associated with necrotizing enterocolitis (NEC, stage II or greater). STUDY DESIGN Single-institution retrospective birth cohort of preterm infants with gestational age 23(0/7) to 34(6/7) weeks delivered between 1 January 2002 and 31 December 2011, excluding infants who received comfort care. Patients were classified into severe CHD, mild CHD and control groups. RESULTS Among 4678 infants, 170 (3.6%) had CHD and 118 (2.5%) developed NEC. The risk for NEC increased with severe CHD (adjusted relative risk (RR)=3.72; 95% confidence interval (CI)=1.37 to 10.10) but not with mild CHD (RR=0.65; CI=0.27 to 1.55). CONCLUSION In this cohort, severe but not mild CHD was independently associated with increased risk for NEC. This finding, if confirmed by other studies, may help identify patients at risk for NEC.

Abstract
Prematurity is a recognized risk factor for morbidity and mortality following cardiac surgery. Postoperative and long-term outcomes after cardiac surgery performed in the preterm period are poorly described. The aim of this study was to analyze a population of preterm neonates operated on for critical congenital heart disease (CHD) before 37 weeks of gestational age (wGA) with special attention given to early and late mortality and morbidity. Between 2000 and 2013, 28 preterm neonates (median gestational age (GA) 34.3 weeks) underwent cardiopulmonary bypass (CPB) surgery for critical CHD before 37 wGA; records were retrospectively reviewed. All patients except three with single ventricle physiology had a single-stage anatomic repair. Overall mortality was 43 % (95 % CI 25-62). Risk factors for death were birth weight (p = 0.032) and weight at surgery (p = 0.037), independently of GA, preoperative status, CPB and aortic clamp time. Seven patients, including those with univentricular hearts, died during the postoperative period, and five in the first year after surgery. Median follow-up was 5.9 years (range 1 month-12.8 years). Kaplan-Meier survival rate was 75 % (95 % CI 59-91) at 1 month, and 57 % (95 % CI 39-75) at 1 and 5 years. Eight patients required reoperations after a delay of 2.8 ± 1.3 months; eight had bronchopulmonary dysplasia. At the end of follow-up, nine patients were asymptomatic. One-stage biventricular repair for critical CHD on preterm neonates was feasible. Mortality remained high but acceptable, mainly confined to the first postoperative year and related to small weight. Despite reoperations, long-term clinical status was good in most survivors. Further long-term prospective investigations are necessary to evaluate neurodevelopmental outcomes.

Abstract
Isolated congenital complete heart block (CCHB) is a rare disease with significant associated morbidity and mortality. A diagnosis is often made in fetal life, but data regarding long-term outcomes are limited, and fetal therapy to improve prognosis is controversial. In our institution, 85 fetuses were diagnosed with CCHB from 1981 to 2013 in 80 mothers. There were 37 anti-Ro-positive pregnancies, 36 both anti-Ro and anti-La positive, 10 antibody negative, and 2 of unknown antibody status. Antenatal treatments were given in 14 fetuses, with 8 given fluorinated steroids, 4 beta sympathomimetics, and both in 2. Of the original 85, 74 babies survived to delivery. Fetal hydrops was the only risk factor found to be significantly associated with intrauterine death (p <0.001). Four babies died before pacemaker implantation, 56 have had pacemakers implanted, and 14 are pacemaker free. The Kaplan-Meier estimate for median time to pacemaker implantation was 2.6 years, with 15 implanted in the neonatal period. There have been 14 postnatal deaths, with a Kaplan-Meier estimate of survival at 30 years of 76.8% (95% confidence interval 65% to 90%). Dilated cardiomyopathy was uncommon, occurring in 6 patients. Prematurity and hydrops were associated with increased postnatal mortality (p = 0.02 and 0.005, respectively). In conclusion, we present the largest single-unit experience of prenatally diagnosed CCHB in the published literature. Our cohort was conservatively managed, with survival similar to those previously published. These data offer insight into the long-term natural history of CCHB.

Abnormal development of thalamic microstructure in premature neonates with congenital heart disease. Pediatr Cardiol 2015; 36:960-9.

Abstract
Preterm birth is associated with alteration in corticothalamic development, which underlies poor neurodevelopmental outcomes. Our hypothesis was that preterm neonates with CHD would demonstrate abnormal thalamic microstructure when compared to critically ill neonates without CHD. A secondary aim was to identify any association between thalamic microstructural abnormalities and perioperative clinical variables. We compared thalamic DTI measurements in 21 preterm neonates with CHD to two cohorts of neonates without CHD: 28 term and 27 preterm neonates, identified from the same neonatal intensive care unit. Comparison was made with three other selected white matter regions using ROI manual-based measurements. Correlation was made with post-conceptional age and perioperative clinical variables. In preterm neonates with CHD, there were age-related differences in thalamic diffusivity (axial and radial) compared to the preterm and term non-CHD group, in contrast to no differences in anisotropy. Contrary to our hypothesis, abnormal thalamic and optic radiation microstructure was most strongly associated with an elevated first arterial blood gas pO2 and elevated preoperative arterial blood gas pH (p < 0.05). Age-related thalamic microstructural abnormalities were observed in preterm neonates with CHD. Perinatal hyperoxemia and increased perioperative serum pH were associated with abnormal thalamic microstructure in preterm neonates with CHD. This study emphasizes the vulnerability of thalamocortical development in the preterm neonate with CHD.

Abstract
Transposition of the great arteries (TGA) requires early surgical repair during the neonatal period. Several preoperative factors have been identified for the postoperative poor outcome after arterial switch operation (ASO). However, the data remain uncertain an association. Therefore, we investigated the preoperative factors which affect the early postoperative outcomes. Between March 2005 and May 2012, a retrospective study was performed which included 126 infants with an ASO for TGA. Preoperative data included the vasoactive inotropic score (VIS) and baseline hemodynamics. Early postoperative outcomes included the duration of mechanical ventilation, the length of stay in the intensive care unit and hospital, and early mortality. Multivariate linear regression and receiver operating characteristics analysis were performed. The duration of mechanical ventilation was significantly correlated with the preoperative mechanical ventilator support and VIS, and CPB time. On multivariate linear regression analysis, a higher preoperative VIS, preoperative B-type natriuretic peptide (BNP) level, and the CPB time were identified as independent risk factors for delayed mechanical ventilation. Preoperative VIS (OR 1.154, 95 % CI 1.024-1.300) and the CPB time (OR 1.034, 95 % CI 1.009-1.060) were independent parameters predicting early mortality. A preoperative VIS of 12.5 had the best combined sensitivity (83.3 %) and specificity (85.3 %) and an AUC of 0.852 (95 % CI 0.642-1.061) predicted early mortality. Our results suggest that preoperative VIS and BNP can predict the need for prolonged postoperative mechanical ventilation. Moreover, preoperative VIS may be used as a simple and feasible indicator for predicting early mortality.

Abstract
BACKGROUND Although human milk (HM) is the recommended form of infant nutrition, the provision of HM feeding among infants with congenital heart disease in the cardiac intensive care unit is unknown. Therefore the aim of the study was to understand the prevalence of pumping initiation, HM feeding, and breastfeeding patterns of mothers and their infants born with congenital heart disease. SUBJECTS AND METHODS This was a prospective cohort study conducted a large children's hospital with a cardiac referral program and unit. All women with infants with congenital heart disease were approached for enrollment in order to document HM prevalence. RESULTS The majority of women (89%) initiated lactation via pumping for their infants. On average, mothers pumped five to six times per day, and mothers were able to achieve a milk supply of over 500 mL/day. Once infants received enteral feeds, over 70% of the infant diet was HM. Very few (13%) infants fed via direct breastfeedings; rather, they received HM via gavage or bottle. There was a significant difference in pumping initiation based on where the infant was born, with mothers delivering in the hospital having a significantly higher pumping initiation rate (96% born in this hospital, 67% born in an outside hospital). CONCLUSIONS Mothers who have infants diagnosed with congenital heart disease should be encouraged to initiate pumping for their infants. Future research is warranted regarding the dose response of HM and specific health outcomes and the need for postdischarge services for these families.

Outcomes of cardiac surgery in patients weighing <2.5 kg: affect of patient-dependent and -independent variables. J Thorac Cardiovasc Surg 2014; 148:2499-506.e1.

Abstract
OBJECTIVE A recent Society of Thoracic Surgeons database study showed that low weight (<2.5 kg) at surgery was associated with high operative mortality (16%). We sought to assess the outcomes after cardiac repair in patients weighing <2.5 kg versus 2.5 to 4.5 kg in an institution with a dedicated neonatal cardiac program and to determine the potential role played by prematurity, the Society of Thoracic Surgeons-European Association for Cardio-Thoracic Surgery (STAT) risk categories, uni/biventricular pathway, and surgical timing. METHODS We analyzed the outcomes (hospital mortality, early reintervention, postoperative length of stay, mortality [at the last follow-up point]) in patients weighing <2.5 kg at surgery (n = 146; group 1) and 2.5 to 4.5 kg (n = 622; group 2), who had undergone open or closed cardiac repairs from January 2006 to December 2012 at our institution. The statistical analysis was stratified by prematurity, STAT risk category, uni/biventricular pathway, and usual versus delayed surgical timing. Univariate versus multivariate risk analysis was performed. The mean follow-up was 21.6 ± 25.6 months. RESULTS Hospital mortality in group 1 was 10.9% (n = 16) versus 4.8% (n = 30) in group 2 (P = .007). The postoperative length of stay and early unplanned reintervention rate were similar between the 2 groups. Late mortality in group 1 was 0.7% (n = 1). In group 1, early outcomes were independent of the STAT risk category, uni/biventricular pathway, or surgical timing compared with group 2. A lower gestational age at birth was an independent risk factor for early mortality in group 1. CONCLUSIONS A dedicated multidisciplinary neonatal cardiac program can yield good outcomes for neonates and infants weighing <2.5 kg independently of the STAT risk category and uni/biventricular pathway. A lower gestational age at birth was an independent risk factor for hospital mortality.

Abstract
BACKGROUND Gestational age at birth is a potentially important modifiable risk factor in neonates with congenital heart disease. We evaluated the relationship between gestational age and outcomes in a multicenter cohort of neonates undergoing cardiac surgery, focusing on those born at early term (ie, 37-38 weeks' gestation). METHODS AND RESULTS Neonates in the Society of Thoracic Surgeons Congenital Heart Surgery Database who underwent cardiac surgery between 2010 and 2011 were included. Multivariable logistic regression was used to evaluate the association of gestational age at birth with in-hospital mortality, postoperative length of stay, and complications, adjusting for other important patient characteristics. Of 4784 included neonates (92 hospitals), 48% were born before 39 weeks' gestation, including 31% at 37 to 38 weeks. Compared with a 39.5-week gestational age reference level, birth at 37 weeks' gestational age was associated with higher in-hospital mortality, with an adjusted odds ratio (95% confidence interval) of 1.34 (1.05-1.71; P=0.02). Complication rates were higher and postoperative length of stay was significantly prolonged for those born at 37 and 38 weeks' gestation (adjusted P<0.01 for all). Late-preterm births (34-36 weeks' gestation) also had greater mortality and postoperative length of stay (adjusted P≤0.003 for all). CONCLUSIONS Birth during the early term period of 37 to 38 weeks' gestation is associated with worse outcomes after neonatal cardiac surgery. These data challenge the commonly held perception that delivery at any time during term gestation is equally safe and appropriate and question the related practice of elective delivery of fetuses with complex congenital heart disease at early term.

Abstract
Premature infants with very low birth weight with tetralogy of Fallot and pulmonary atresia (TOF/PA) have been shown to have poor surgical outcomes. Palliating these patients by stenting the right ventricular outflow tract (RVOT) has been shown to be safe and effective. In patients with very low birth weight, a hybrid perventricular approach offers the ability to perform pulmonary valve perforation and RVOT stent placement while avoiding cardiopulmonary bypass and femoral vessel complications in the neonatal period. We present a hybrid perventricular treatment of a patient weighing 1.3 kg with TOF/PA.

Abstract
BACKGROUND AND PURPOSE Abnormal cerebral microstructure has been documented in term neonates with congenital heart disease, portending risk for injury and poor neurodevelopmental outcome. Our hypothesis was that preterm neonates with congenital heart disease would demonstrate diffuse cerebral microstructural abnormalities when compared with critically ill neonates without congenital heart disease. A secondary aim was to identify any association between microstructural abnormalities, white matter injury (eg, punctate white matter lesions), and other clinical variables, including heart lesions. MATERIALS AND METHODS With the use of tract-based spatial statistics, an unbiased, voxelwise method for analyzing diffusion tensor imaging data, we compared 21 preterm neonates with congenital heart disease with 2 cohorts of neonates without congenital heart disease: 28 term and 27 preterm neonates, identified from the same neonatal intensive care unit. RESULTS Compared with term neonates without congenital heart disease, preterm neonates with congenital heart disease had microstructural abnormalities in widespread regions of the central white matter. However, 42% of the preterm neonates with congenital heart disease had punctate white matter lesions. When neonates with punctate white matter lesions were excluded, microstructural abnormalities remained only in the splenium. Preterm neonates with congenital heart disease had similar microstructure to preterm neonates without congenital heart disease. CONCLUSIONS Diffuse microstructural abnormalities were observed in preterm neonates with congenital heart disease, strongly associated with punctate white matter lesions. Independently, regional vulnerability of the splenium, a structure associated with visual spatial function, was observed in all preterm neonates with congenital heart disease.

Abstract
OBJECTIVE Necrotising enterocolitis is a rare, though catastrophic complication that may occur in term newborns with congenital heart disease. There is considerable controversy regarding the factors that lead to necrotising enterocolitis in this population. We sought to determine the incidence of necrotising enterocolitis among term and near-term newborns with congenital heart disease, focusing on the relationship of enteral feeding to this complication. METHODS In this retrospective study, we identified the incidence of necrotising enterocolitis among 1551 newborns admitted to our cardiac intensive care unit between July 1, 2002 and July 1, 2010. In order to understand the impact of enteral feeding upon the development of necrotising enterocolitis, we undertook a nested 2:1 matched case-control analysis to compare feeding patterns in an age- and lesion-matched control population. RESULTS Necrotising enterocolitis developed in 45 term or near-term infants (3%). The majority of these cases, 27 (60%), occurred in the post-operative period after the introduction of enteral feeds. This subgroup was used for matched analysis. There were no differences in enteral feeding patterns among the patients who developed necrotising enterocolitis and their matched controls. The overall mortality rate for patients who developed necrotising enterocolitis was 24.4% (11 out of 45). CONCLUSIONS Despite numerous advances in the care of infants with congenital heart disease, necrotising enterocolitis remains a significant source of morbidity and mortality. In these infants, there is no clear relationship between enteral feeding patterns and the development of necrotising enterocolitis in the post-operative period. The benefits of graduated feeding advancements to avoid the development of necrotising enterocolitis remain unproven.

Abstract
Significant advances in technology and therapy have led to dramatic improvements in the survival of preterm babies over the last 2 decades. Similarly, improvements in surgical and cardiac intensive care techniques have increased the feasibility of supporting even very small babies to the point of surgical repair, leading some to adopt an approach of early and complete surgical repair in preterm infants, with the aim of minimizing potential preoperative morbidity associated with extended medical management or surgical palliation. (1,2) However, multiple diagnostic and therapeutic challenges complicate the care of premature infants. Major errors in echocardiography are more common in neonates weighing less than 2.5 kg, (3) and the ideal timing and type of surgical intervention in premature infants remains unknown. These problems are compounded by the need for critical care practices that optimize management of immature cardiopulmonary, gastrointestinal, and neurological systems. This review will summarize some of the recent advances in neonatal and perinatal medicine, which have the potential to contribute to improved management of preterm infants with critical cardiac disease.

Abstract
Prematurity and low birth weight adds to the risk of serious congenital heart disease in infants. It may also delay surgical intervention, especially when cardiopulmonary bypass is required, or where an aortopulmonary shunt is necessary to maintain adequate oxygenation. In this setting, neonatologists are faced with the challenge of accelerating the infant's growth to allow for early surgery. We describe the cases of two infants in whom an attempt to fortify the feeds was associated with necrotising enterocolitis, with a lethal outcome in one. The outcome suggests caution in fortifying feeds in premature infants with serious congenital heart disease.

Abstract
PURPOSE To study the association between congenital heart diseases (CHD) and in-hospital mortality and morbidity of very preterm/very low birth weight (VLBW) infants. METHODS The area-based prospective cohort study ACTION included all infants with gestational age (GA) 22-31 weeks or birth weight <1,500 g admitted to neonatal care between July 2003 and June 2005 in six Italian regions (n = 3,684). CHD were coded according to ICD9-CM. Cluster multivariable logistic regression analyses were used to assess the relationship between CHD and mortality and selected morbidities [neonatal infection, ultrasound brain abnormalities, retinopathy of prematurity (ROP), and bronchopulmonary dysplasia (BPD)] adjusting for potential confounders. RESULTS Seventy-one patients had CHD [19.3 ‰, 95 % confidence interval (CI) 15.1-24.2 ‰]. The most common lesions were isolated atrial and ventricular septal defects (31.1 and 26.8 %, respectively), pulmonary valvar stenosis (12.7 %), and tetralogy of Fallot (5.6 %). Compared with other infants, CHD patients showed significantly higher GA and frequency of small for gestational age (SGA, i.e., birth weight ≤3rd centile). After adjustment for GA, sex, SGA, presence of extracardiac malformations or chromosomal anomalies, and region of birth, CHD patients had a significantly higher likelihood of infection, BPD, ROP, and, after 27 weeks gestation only, hospital mortality. The increased risk of ROP appeared to be partly due to infection. CONCLUSIONS In very preterm/VLBW infants CHD are more prevalent than in the general liveborn population, and confer an increased risk of death and serious morbidities independently of other risk factors. These results may be useful to better tailor prognostic assessment and diagnostic and therapeutic interventions for these children.

Abstract
Conventional management of low birth weight and very low birth weight neonates was composed of deferring corrective surgery by aggressive medical management or palliative surgery which does not require cardiopulmonary bypass. However, while waiting for weight gain, these neonates are at risk for various comorbidities. In the current era, this "wait and let the baby grow" approach has not been shown to result in better clinical outcomes. Early primary repair hence has become the standard strategy for congenital heart disease requiring surgery in these neonates. However, there still exist some circumstances, which are considered to be unfavorable for corrective surgery due to medical, physiologic, surgeon's technical and institutional-systemic factors. We reviewed the recent literature and examined the reasons for delaying or not delaying surgery.

Abstract
BACKGROUND AND OBJECTIVES Preterm birth (PTB) and congenital heart defect (CHD) are 2 major causes of mortality and disability of perinatal origin. There are limited data on the relation between CHD and PTB. Our objective was to use population-based data to estimate the risk of PTB in newborns with CHD and to study specific associations between categories of CHD and PTB. METHODS We used data from a population-based cohort study of CHD (EPIdémiologique sur le devenir des enfants porteurs de CARDiopathies congénitales study), including 2189 live births with CHD (excluding isolated atrial septal defects) born between 2005 and 2008. We categorized CHD by using an anatomic and clinical classification. Data from the French National Perinatal Survey of 2003 were used to compare PTB in the EPIdémiologique sur le devenir des enfants porteurs de CARDiopathies congénitales study to that of the general population. RESULTS Of the newborns with CHD, 13.5% were preterm. The odds of PTB were twofold higher than for the general population (odds ratio 2.0, 95% confidence interval 1.6-2.5), essentially due to an increase in spontaneous PTB for newborns with CHD. The risk of PTB associated with CHD persisted after exclusion of chromosomal or other anomalies. There were significant variations in risk of PTB across the categories of CHD after adjustment for known risk factors of PTB and factors related to medical management of pregnancy and delivery. CONCLUSIONS We found a higher risk of PTB in newborns with CHD, which was essentially due to spontaneous PTB. Risk of PTB varied for categories of CHD. Our finding may be helpful for generating hypotheses about the developmental links between CHD and PTB.

Abstract
Purpose With feasibility in the diagnoses of congenital heart disease (CHD) in the antenatal period, we suspect changes have occurred in its incidence. No data have been reported about the current incidence of simple forms of CHD in Korea. We have attempted to assess the recent incidence and characteristics of CHD in the neonatal care unit of a secondary referral medical center. Methods Medical records of 497 neonatal care unit patients who underwent echocardiography in the past 5 years were reviewed. Pre-term infants with patent ductus arteriosus and other transient, minimal lesions were excluded from this study. Results Although the number of inpatients remained stable, the incidence of simple forms of CHD showed a gradual decrease over the 5-year study period; a markedly low incidence of complex forms was seen as well. CHD was observed in 3.7% full-term and 6.8% pre-term infants. CHD was observed in 152 infants weighing >2,500 g (3.5% of corresponding birth weight infants); 65 weighing 1,000 to 2,500 g (9.3%); and 6 weighing <1,000 g (8.0%). The incidence of CHD was higher in the pre-term group and the low birth weight group than in each corresponding subgroup (P<0.001); however, the incidence of complex CHD in full-term neonates was high. The number of patients with extracardiac structural anomalies has also shown a gradual decrease every year for the past 5 years. Conclusion Findings from our study suggest that the recent incidence and disease pattern of CHD might have changed for both complex and simple forms of CHD in Korea.

Abstract
OBJECTIVE To examine prevalence, characteristics, interventions, and mortality of very low birth weight (VLBW) infants with trisomy 21 (T21), trisomy 18 (T18), trisomy 13 (T13), or triploidy. STUDY DESIGN Infants with birth weight 401-1500 g admitted to centers of the Vermont Oxford Network during 1994-2009 were studied. A majority of the analyses are presented as descriptive data. Median survival times and their 95% CIs were estimated using the Kaplan-Meier approach. RESULTS Of 539 509 VLBW infants, 1681 (0.31%) were diagnosed with T21, 1416 (0.26%) with T18, 435 (0.08%) with T13, and 116 (0.02%) with triploidy. Infants with T18 were the most likely to be growth restricted (79.7%). Major surgery was reported for 30.4% of infants with T21, 9.2% with T18, 6.4% with T13, and 4.8% with triploidy. Hospital mortality occurred among 33.1% of infants with T21, 89.0% with T18, 92.4% with T13, and 90.5% with triploidy. Median survival time was 4 days (95% CI, 3-4) among infants with T18 and 3 days (95% CI, 2-4) among both infants with T13 and infants with triploidy. CONCLUSION In this cohort of VLBW infants, survival among infants with T18, T13, or triploidy was very poor. This information can be used to counsel families.

Abstract
OBJECTIVE We evaluated the effect of late preterm delivery (34 to 36 weeks) on hospital mortality of infants with congenital heart defects (CHDs). STUDY DESIGN Retrospective record review of infants with major CHD born at or after to 34 weeks, cared for in a single tertiary perinatal center between 2002 and 2009. Factors associated with death before discharge from the hospital were ascertained using univariate and multivariate analyses. RESULT Of the 753 infants with CHD, 117 were born at late preterm. Using logistic regression analysis, white race (OR; 95% CI) (0.60; 0.39 to 0.95), late preterm delivery (2.70; 1.69 to 4.33), and need for intubation in the delivery room (3.15; 1.92 to 5.17) were independently associated with hospital death. CONCLUSION Late preterm birth of infants with major CHDs was independently associated with increased risk of hospital death compared with delivery at more mature gestational ages.

Abstract
We sought to describe contemporary outcomes and identify risk factors for hospital mortality in premature neonates with critical congenital heart disease who were referred for early intervention. Neonates who were born before 37 weeks' gestation with critical congenital heart disease and admitted to our institution from 2002 to 2008 were included in this retrospective cohort study. Critical congenital heart disease was defined as a defect requiring surgical or transcatheter cardiac intervention or a defect resulting in death within the first 28 days of life. Logistic regression analyses were performed to identify risk factors for mortality before hospital discharge. The study included 180 premature neonates, of whom 37 (21%) died during their initial hospitalization, including 6 (4%) before cardiac intervention and 31 (17%) after cardiac intervention. For the 174 patients undergoing cardiac intervention, independent risk factors for mortality were a 5 min Apgar score ≤ 7, need for preintervention mechanical ventilation, and Risk Adjustment in Congenital Heart Surgery category ≥ 4 or not assignable. Mortality for premature infants with critical congenital heart disease who are referred for early intervention remains high. Patients with lower Apgar scores who receive preintervention mechanical ventilation and undergo more complex procedures are at greatest risk.

STUDY DESIGN The 2000 to 2003 national linked birth/infant death cohort datasets were obtained. Congenital heart disease deaths were identified by using International Statistical Classification of Diseases, 10th Revision codes. Proportional death rates were calculated by using congenital heart disease deaths and all live births. The relationship between congenital heart disease death rates and gestational age was determined. Death rates were compared across intervals. RESULTS A total of 14.9 million records were analyzed. Congenital heart disease deaths occurred in 4736 infants (0.04%) born between 34 and 40 weeks. There was a significant, negative linear relationship between congenital heart disease death rate and gestational age (R(2) = 0.97). Comparisons across 1-week intervals varied (P = .02-.23). All 2-week intervals were statistically significant (P < .01). CONCLUSIONS Congenital heart disease death rates decrease as gestational age approaches 40 weeks. These results should be considered before elective delivery for the sole indication of prenatally diagnosed congenital heart disease.

Abstract
AIM To evaluate outcomes of late preterm (34-36 6/7 weeks gestation) infants with congenital heart defects requiring surgical intervention during initial admission (added), in comparison with term (37-42 weeks) controls. METHODS This was a retrospective chart review of consecutive late preterm and term infants with congenital heart lesions, requiring surgical intervention during initial admission. RESULTS Our cohort (n=88) comprised 26 late preterm infants (group 1) and 62 term controls (group 2). The two groups differed significantly in mean (SD) gestation [34.5 (1.5) vs. 39.1 (1) weeks)], birth weight [2335 (402) vs. 3173 (401) g] and weight [2602 (739) vs. 3273 (507) g] and age [33 (51) vs. 11 (14) days] at surgery. Cardiac diagnosis frequencies were similar in both groups. The mean (SD) duration of PGE1 [31.9 (56.8) vs. 11.3 (24.9) days] and need for preoperative pressors (25% vs. 8%) were significantly higher in group 1. Death (23% vs. 8%, p=0.05) tended to be higher in group 1. Rates of necrotizing enterocolitis (23% vs. 1.7%), seizures (19% vs. 0%), oxygen need (12% vs. 0%) and gavage feeds (12% vs. 1.6%) at discharge were all significantly higher in the late preterm cohort. CONCLUSIONS These data highlight the extreme vulnerability of infants with the 'double hits' of prematurity and heart defects.

Abstract
Although the outcome of neonatal cardiac surgery has dramatically improved, low body weight (LBW) is still considered an important risk for open heart surgery. The factors contributing to poor outcomes in LBW infants, however, are still unclear. We investigated risk factors for poor outcomes in infants weighing <2500 g who underwent surgical correction with cardiopulmonary bypass (CPB). From January 1995 to December 2009, 102 consecutive patients were included in this study. Median age and body weight at the time of surgery was 19 (range 1 to 365) days and 2.23 kg (range 1.3 to 2.5), respectively. Corrective surgery was performed on 75 infants. The median follow-up duration was 45.03 months (range 0.33 to 155.23). There were 23 (22.5%) hospital mortalities. Emergency surgery and low cardiac output (LCO) were associated with early mortality; however, body weight, Aristotle basic complex score, and type of surgery was not. Early morbidities, including delayed sterna closure, arrhythmia, and chylothorax, occurred in 39 (38.2%) infants. The overall actuarial survival rate at 10 years was 74.95% ± 4.37%. In conclusion, among infants weighing <2500 g who underwent open heart surgery with CPB, perioperative hemodynamic status, such as emergency surgery and LCO, strongly influenced early mortality. In contrast, LBW itself was not associated with patient morbidity or mortality.

Abstract
Infants of birth weight ≤2500 g are termed low birth weight (LBW). These children often have considerable morbidity from prematurity and intra-uterine growth restriction. Additionally, LBW infants have increased risk for cardiac and noncardiac congenital anomalies and may require surgery. Primary rather than palliative surgical repair of cardiac lesions has been preferred in recent years. However, LBW remains a risk factor for increased mortality and morbidity after open-heart surgery (OHS). There is a paucity of information about the anesthetic challenges presented by LBW infants undergoing OHS. This review summarizes the perioperative issues of relevance to anesthesiologists who manage these high-risk patients. Emphasis is placed on management concerns that are unique to LBW infants. Retrospective data from the authors' institution are provided for those aspects of anesthetic care that lack published studies. Successful outcome often requires substantial hospital resources and collaborative multi-disciplinary effort.
