RESUMO
As survivors of early cardiac surgery are at high risk of neurodevelopmental impairments, systematic health observations of children with critical congenital heart disease (CCHD) throughout childhood are recommended to enable early diagnosis and offer interventions to optimize neurodevelopment. A qualitative study using thematic analysis was performed to explore parents' concerns, experiences, and needs regarding the development and received developmental care of their child (0-10 years) during hospital admission and beyond. Data were collected using semi-structured online interviews with 20 parents of children with CCHD. Four major themes were identified: (1) "impact of diagnosis and disease on the family-system," (2) "parental concerns from diagnoses and beyond," (3) "the need for information," and (4) "the need for individualized and family-centered care." The main themes can be divided into 13 sub-themes as impact, concerns, and needs are influenced by various impactful moments from diagnosis and afterwards. Conclusion: This study confirms the importance of early identification of neurodevelopmental problems by experienced healthcare professionals, especially in the early years when parental expectations and concerns about their child's neurodevelopment are lower. A tailor-made family-centered follow-up program should be offered, which pays attention to both the neurodevelopment of patients with CCHD as well as the mental wellbeing of the entire family system. Furthermore, an online portal is recommended with a variety of reliable, controlled, understandable information from which parents can obtain the desired information to understand better the consequences of specific heart condition and to provide their child with the best possible guidance. What is Known: ⢠Survivors of early cardiac surgery are at high risk of neurodevelopmental impairments; systematic health observations of children with CCHD throughout childhood are strongly recommended. What is New: ⢠Parents need a tailor-made family-centered follow-up program, which pays attention to both the neurodevelopment of patients with CCHD as well as the mental wellbeing of the entire family system. ⢠An online portal offering diverse, trustworthy information and sources would effectively meet parents' needs by providing accessible insights into the potential consequences of specific heart conditions and guiding them in supporting their child optimally.

BACKGROUND: Prenatal detection of critical congenital heart disease (CCHD) optimises perinatal decision-making and neonatal outcomes. The objective of this study was to determine the prenatal screening performance, care pathways and perinatal outcomes for prenatally and postnatally diagnosed cases of CCHD over a four-year period. STUDY DESIGN: This retrospective cohort study in a tertiary centre and its two affiliated secondary sites examined all cases of CCHD, including cases of pregnancy termination and in-utero fetal death, neonatal death and liveborn babies that underwent cardiac catheterization or surgery in the first six weeks of life. Prenatal and postnatal data were ascertained from the first trimester assessment for all patients diagnosed prenatally. Cases requiring intervention that were first identified in the postnatal period were included to determine prenatal detection rates. Follow-up for all cases of CCHD continued to one year of age. RESULTS: In a consecutive cohort of 49,950 pregnancies in a 4-year period 01/2019 to 12/2022, a prenatal diagnosis of CCHD was made in 96 cases, yielding a prevalence of 1.9 per 1000 births. The prenatal detection for right duct-dependant heart pathology and congenital heart block was 100%, 85% for left duct-dependant pathology and 93% for transposition of the great arteries (TGA). In the prenatally diagnosed group, 37% of cases were complicated by extracardiac structural abnormalities, a genetic diagnosis or both. All cases of prenatal detection were identified in the context of routine anatomy screening rather than specialist Fetal Cardiac screening services. Almost half of all pregnancies complicated by CCHD did not undergo neonatal cardiac intervention, by virtue of parental choice determined either prenatally or after birth. An additional eight babies were diagnosed with CCHD in the neonatal period, such that the prenatal detection rate for CCHD was 92% (96/104, 95% CI = 84%-96%). Survival at 1-year for infants deemed suitable for CCHD surgery was 85%. CONCLUSION: In a large unselected population, optimal rates of prenatal detection of critical congenital heart disease can be achieved by a protocolised approach to mid-trimester fetal anatomy ultrasound, underpinned by a programme of sonographer education and training. The cardiac abnormalities most likely to evade prenatal detection are left-sided obstructive lesions.

BACKGROUND: The aim of this study was to examine the characteristics of infant mortality associated with critical congenital heart disease (CCHD). METHODS: In a cross-sectional study, data for the study were obtained through Death Notification System, Birth Notification System and Turkish Statistical Institute birth statistics. RESULTS: Of all infant deaths, 9.8% (4083) were associated with CCHD, and the infant mortality rate specific to CCHD was 8.8 per 10,000 live births. CCHD-related infant deaths accounted for 8.0% of all neonatal deaths, while the CCHD specific neonatal death rate was 4.6 per 10,000 live births. Of the deaths 21.7% occurred in the early neonatal, 30.3% in the late neonatal and 48.0% in the post neonatal period. Group 1 diseases accounted for 59.1% (n = 2415) of CCHD related infant deaths, 40.5% (n = 1652) were in Group 2 and 0.4% (n = 16) were in the unspecified group. Hypoplastic left heart syndrome was the most common CCHD among infant deaths (n = 1012; 24.8%). The highest CCHD related mortality rate was found in infants with preterm birth and low birth-weight while multiparity, maternal age ≥ 35 years, twin/triplet pregnancy, male gender, maternal education in secondary school and below, and cesarean delivery were also associated with higher CCHD related infant mortality rate. There was at least one non-cardiac congenital anomaly/genetic disorder in 26.1% of all cases. CONCLUSION: CCHD holds a significant role in neonatal and infant mortality in Türkiye. To mitigate CCHD-related mortality rates, it is crucial to enhance prenatal diagnosis rates and promote widespread screening for neonatal CCHD.

Duct-dependent pulmonary circulation has traditionally been addressed by the Blalock-Taussig-Thomas shunts (BTTS). Recently, catheter-based alternatives such as ductal stenting have emerged as a particularly advantageous option, especially in resource-constrained settings. This article delves into the nuances of ductal stenting within low-resource environments, highlighting its relative ease of application, reduced morbidity, and cost-effectiveness as key factors in its favor. Comparisons in mortality between the two procedures are however likely to be confounded by selection biases. Ductal stenting appears to be particularly beneficial for palliating older infants and children with cyanotic congenital heart disease and diminished pulmonary blood flow who present late. Additionally, it serves as a valuable tool for left ventricular training in late-presenting transposition with an intact ventricular septum. A meticulous pre-procedure echocardiographic assessment of anatomy plays a pivotal role in planning access and hardware, with additional imaging seldom required for this purpose. The adaptation of adult coronary hardware has significantly enhanced the technical feasibility of ductal stenting. However, challenges such as low birth weight and sepsis specifically impact the performance of ductal stenting and patient recovery in low-resource environments. There is potential for systematic application of quality improvement processes to optimize immediate and long-term outcomes of ductal stenting. There is also a need to prospectively examine the application of ductal stenting in low-resource environments through multi-center registries.
RESUMO
BACKGROUND: The aim of this study is to examine the features of critical congenital heart disease (CCHD). METHODS: The study was planned as a retrospective cohort study. Data for the study were obtained through national data collection systems and 2018-2020 CCHD cohort was established. In this study, we divided the patients into two groups: Group 1 included seven primary target diseases of the newborn CCHD screening program and Group 2 included secondary target diseases. RESULTS: There were 9884 CCHD cases, with a prevalence of 27.8 per 10,000 live births. Of the cases 44.4% were in Group 1 (12.3 per 10,000) and 54.8% were in Group 2 (15.2 per 10,000). Of all cases 55.5% were male and the female/male ratio was 1/1.2. While 21.8% of the cases were premature, 23.0% were babies with low birth weight (LBW), 4.8% were born from multiple pregnancies. The highest prevalence of CCHD was found in LBW (84.8 per 10,000), premature infants (57.8 per 10,000) (p < 0.001). The fatality rate in the cohort was 16.6% in the neonatal period, 31.6% in the first year of life respectively. The mean estimated survival time in the birth cohort was 40.0 months (95% CI: 39.5-40.6). The mean survival time for Group 1 diseases was 33.4 months (95% CI: 32.5-34.2), while it was 45.4 months (95% CI: 44.7-46.0) for Group 2 diseases (p < 0.001). Preterm birth, LBW, maternal age and region were evaluated as factors associated with mortality risk. CONCLUSION: This study showed that CCHDs are common in Turkey and mortality rates are high. There are regional differences in CCHD both prevalence and survival. Improving prenatal diagnosis rates and expanding neonatal CCHD screening are of key importance.

Advances in fetal cardiac imaging over the last few decades have allowed for increased prenatal detection and detailed counseling of congenital heart disease (CHD). When CHD is detected, fetal cardiologists are faced with the challenge of providing nuanced prenatal counseling. Studies in other specialties have shown that differences in physician attitudes exist around termination of pregnancy and correlate with variations in the counseling provided to parents. We conducted an anonymous cross-sectional survey of fetal cardiologists in New England (n = 36) regarding attitudes toward termination of pregnancy and the counseling provided to parents with a fetal diagnosis of hypoplastic left heart syndrome. Using a screening questionnaire, there was no significant difference in the counseling provided to parents regardless of the physician's personal or professional views on termination of pregnancy, age, gender, location, type of practice, or years of experience. There were, however, differences among physicians on reasons to consider termination and their perceived professional responsibility to the fetus or mother. Further investigation on a larger geographic scale may reveal additional insights on variations in physician beliefs and whether such beliefs affect variability in counseling practices.
RESUMO
We evaluated the association between implementation of state-mandated pulse oximetry screening (POS) and rates of emergency hospitalizations among infants with Critical Congenital Heart Disease (CCHD) and assessed differences in that association across race/ethnicity. We hypothesized that emergency hospitalizations among infants with CCHD decreased after implementation of mandated POS and that the reduction was larger among racial and ethnic minorities compared to non-Hispanic Whites. We utilized statewide inpatient databases from Arizona, California, Kentucky, New Jersey, New York, and Washington State (2010-2014). A difference-in-differences model with negative binomial regression was used. We identified patients with CCHD whose hospitalizations between three days and three months of life were coded as "emergency" or "urgent" or occurred through the emergency department. Numbers of emergency hospitalizations aggregated by month and state were used as outcomes. The intervention variable was an implementation of state-mandated POS. Difference in association across race/ethnicity was evaluated with interaction terms between the binary variable indicating the mandatory policy period and each race/ethnicity group. The model was adjusted for state-specific variables, such as percent of female infants and percent of private insurance. We identified 9,147 CCHD emergency hospitalizations. Among non-Hispanic Whites, there was a 22% (Confidence Interval [CI] 6%-36%) decline in CCHD emergency hospitalizations after implementation of mandated POS, on average. This decline was 65% less among non-Hispanic Blacks compared to non-Hispanic Whites. Our study detected an attenuated association with decreased number of emergency hospitalizations among Black compared to White infants. Further research is needed to clarify this disparity.

OBJECTIVES: To investigate the risk factors of postoperative neuro-developmental abnormalities in neonates with critical congenital heart disease (CCHD). METHODS: Clinical data of 50 neonates with CCHD admitted in the Cardiac Intensive Care Unit, The Children's Hospital, Zhejiang University School of Medicine from November 2020 to December 2021 were retrospectively analyzed. Neurological assessment was performed with cranial ultrasonography, CT/MRI, video electroencephalogram and clinical symptoms before and after surgical treatment for all patients, and neurodevelopmental abnormalities were documented. Binary logistic stepwise regression was used to analyze risk factors of postoperative new-onset neurodysplasia in children with CCHD, and the predictive value of the risk factors on postoperative neurodevelopmental abnormalities were evaluated using the receiver operating characteristic (ROC) curve. RESULTS: Neurodevelopmental abnormalities were detected in 22 cases (44.0%) and not detected in 28 cases (56.0%) before surgery. There were no significant differences in gender, birth weight, age at admission, gestational age, preoperative SpO2 level, prematurity, cyanotic congenital heart disease, and ventilator support between the two groups (all P>0.05). After surgery, there were 22 cases (44.0%) with new-onset neurological abnormalities and 28 cases (56.0%) without new-onset abnormalities. Multivariate logistic regression analysis showed that postoperative 24 h peak lactic acid (OR=1.537, 95%CI: 1.170-2.018, P<0.01) and postoperative length of ICU stay (OR=1.172, 95%CI:1.031-1.333, P<0.05) were independent risk factors for postoperative new-onset neurodevelopmental abnormalities. The area under ROC curve (AUC) of the postoperative 24 h peak lactic acid for predicting the new-onset neurological abnormalities after operation was 0.829, with cut-off value of 4.95 mmol/L. The diagnostic sensitivity and specificity were 90.0% and 64.3%, respectively. The AUC of postoperative length of ICU stay for predicting the new-onset neurological abnormalities after operation was 0.712, with cut-off value of 18.0 d. The diagnostic sensitivity and specificity were 50.0% and 96.4%, respectively. The AUC of the combination of the two indicators was 0.917, the diagnostic sensitivity and specificity were 95.5% and 64.3%, respectively. CONCLUSIONS: The incidence of neurodysplasia in neonatal CCHD is high, and new neurological abnormalities may occur after surgery. The postoperative 24 h peak lactic acid and postoperative length of ICU stay are risk factors for new-onset neurodysplasia after surgery. The combination of the two indicators has good predictive value for neurodevelopmental outcomes after surgery in CCHD infants.

RESEARCH QUESTION: What is the proportion of infants born as a result of assisted reproductive technology ART across different types of neonatal critical congenital heart disease (CCHD) in a Japanese population? DESIGN: A retrospective analysis of 418 consecutive infants with CCHD that required catheter treatment or surgery within the first 28 days of life or ductal-dependent lesions, in two paediatric centres in Japan, between January 2014 and December 2019. The proportion of ART in infants with each type of CCHD was evaluated. The proportion of ART in infants with univentricular heart defect (UVH) compared with those with biventricular heart defect (BVH) was evaluated. RESULTS: The study group included 229 boys and 189 girls, with a gestational age of 38 ± 2 weeks. Overall, 61 infants (14.6%) were conceived by fertility treatment with 46 (11.0%) conceived by ART. Univentricular heart defect and BVH were identified in 111 infants (26.6%) and 307 infants (73.4%), respectively. The proportion of infants conceived by ART was significantly higher in UVH (16.2%) than in BVH (9.1%) (OR 2.28, 95% CI 1.11 to 4.68, Pâ¯=â¯0.025), regardless of maternal age and maternal history of miscarriage. CONCLUSIONS: The proportion of ART in infants with CCHD, especially UVH, was high. These findings could form the basis of a rationale for carrying out fetal echocardiography in fetuses conceived by ART.

PURPOSE: To conduct a retrospective evaluation of a large clinical implementation of combined pulse oximeter (POX) and cardiac auscultation as a fast-screening device for congenital heart disease (CHD). METHODS: Every newborn in a large maternity healthcare center received auscultation and POX screening within 24 hours after delivery. When an abnormal heart murmur or SpO2 level was detected, an echocardiogram was ordered to confirm the diagnosis of CHD. RESULTS: From January 1, 2018 to December 31, 2019, there were 44,147 livebirths at the studied hospital where 498 suspected CHD were identified: 27 newborns by POX screening and 471 by cardiac auscultation. The diagnosis was further confirmed in 458 neonates through echocardiogram. This result put forth an overall diagnosis rate of 92.0%. Cardiac auscultation detected the majority of CHD cases 438 (95.6%) while POX only screened 20 (4.4%) cases. Interestingly, no CHD case was detected by both auscultation examination and POX screening. Auscultation detected most of the common types of CHD, but POX excelled in identifying rare and critical cases. POX screening alone had a very low accuracy of 74.07% in positive predict value (PPV). On the other hand, auscultation functioned well in terms of PPV and negative predict value (NPV) (92.99 and 99.95%, respectively), but the addition of POX improved the overall screening performance resulting in 100% NPV. We also validate the finding with the data 6 months after the study period. CONCLUSION: Our study demonstrated that addition of pulse oximetry to routine cardiac auscultation could be used as an accurate and feasible screening for early screening of CHD in newborns in large-scale clinical practice.

BACKGROUND: Screening of critical congenital heart disease (CCHD) using pulse oximetry is a routine procedure in many countries, but not in Indonesia. This study aimed to evaluate the feasibility of implementing CCHD screening with pulse oximetry for newborns in Yogyakarta, Indonesia. METHODS: A cross-sectional study was conducted at four hospitals in Yogyakarta, Indonesia. Newborns aged 24-48 hours who met the inclusion criteria were screened on the right hand and left or right foot using a pulse oximeter. Positive results were indicated by: either (1) SpO2 level < 90% in one extremity, (2) SpO2 level of 90-94% in both right hand and either foot on three measurements conducted 1 hour apart, or (3) a saturation difference > 3% between the upper and lower extremity on three measurements conducted 1 hour apart. Positive findings were confirmed by echocardiography. RESULTS: Of 1452 newborns eligible for screening, 10 had positive results and were referred for echocardiographic evaluation. Of those, 8 (6 per 1000 live birth, 8/1452) had CCHD. Barriers found during screening processes were associated with hospital procedures, equipment, healthcare personnel, and condition of the newborn. CONCLUSION: Pulse oximetry screening might be feasible to be implemented within the routine newborn care setting for CCHD in Indonesia. In order to successfully implement pulse oximetry screening to identify CCHD in Indonesia, the barriers will need to be addressed.

BACKGROUND: Almost eight children per 1000 live births are expected to have a congenital heart defect globally. The seven most critical congenital heart conditions that cause severe compromise on the patient's quality and duration of life are collectively referred to as the Critical Congenital Heart Diseases (CCHD). CCHD is a critical condition that requires prompt detection and intervention as a life-saving measure. Pulse oximetry is a non-invasive, highly specific, and moderately sensitive method that can be used for screening new-borns for CCHD. The Emirates Health Services (EHS), UAE, adopted a strategy of developing a stringent program for newborn screening of Critical Congenital Heart disease, which would help in the early diagnosis and treatment of CCHD patients. An automated EMR (Wareed) driven solution was introduced to enhance this program as part of the routine workflow for the nurse care providers. METHODS: Our study is a retrospective observational study that aims to understand: the prevalence of CCHD in our target population and to study the impact of an automated program on screening compliance and its implications for early diagnosis of CCHD. RESULTS: We found that an EMR-driven automated screening program was highly effective in achieving high compliance (98.9%). It created a (statistically significant) improvement in the disease identification for CCHD in live births at EHS facilities. CONCLUSION: We conclude that implementing an automated protocol through the EMR can effectively improve new-born screening coverage. It reduces the days to CCHD diagnosis, which would improve health outcomes in neonates.

Late detection of critical congenital heart disease (CCHD) is multifactorial and ill defined. We investigated the results of pulse oximetry screening (POS) and points in the care chain that contribute to delayed detection of CCHD. The medical records of 13 infants with delayed detection at a single pediatric cardiac center between 2013 and 2016 were identified and reviewed. Left heart obstructive lesions were the most common diagnosis (n = 8; 62%) and included coarctation of the aorta (n = 6), interrupted aortic arch with ventricular septal defect (n = 1), and critical aortic stenosis (n = 1). Tetralogy of Fallot (TOF) (n = 2), truncus arteriosus (n = 1), pulmonary atresia with ventricular septal defect (n = 1), and total anomalous pulmonary venous drainage (n = 1) made up the remainder of the conditions. Routine prenatal care was reported in most infants (10/13). Infants with late detection had either a true negative POS (10/13 infants) or no POS performed (3/13 infants). At the time of detection, 5/6 (83%) infants with coarctation had normal pulse oximetry values, whereas 6/7 (86%) infants with other CCHD developed abnormal pulse oximetry values. At diagnosis, 11/13 (85%) infants had significant signs or symptoms of clinical deterioration; only 2 infants were completely asymptomatic. Late detection of CCHD is uncommon and multifactorial. Eliminating late detection is dependent upon improving detection on screening obstetrical ultrasounds, enforcement of universal POS, and attention to the neonatal physical exam.

BACKGROUND: Congenital heart disease (CHD) is the most common congenital malformation group and is the leading cause of newborn mortality in developed countries. Most of the infants with CHD develop preoperative or postoperative acute kidney injury (AKI). Acute kidney injury may develop before the serum creatinine rise and oliguria. Urinary biomarkers such as kidney injury molecule-1 (KIM-1), neutrophil gelatinase-associated lipocalin (NGAL), interleukin (IL)-18, and cystatin C may predict AKI in patients with critical CHD (CCHD) before the serum creatinine rise. In this study, we aimed to determine the AKI incidence among newborn patients with CCHD and investigate the predictivity of urinary biomarkers for AKI. METHODS: Newborns with a gestational age >34 weeks and birth weight >1500 g with a diagnosis of CCHD were enrolled in the study. Blood and urine samples were collected at birth, during the first 24-48 h, and in the preoperative and postoperative periods. RESULTS: A total of 53 CCHD patients requiring surgery during the neonatal period were enrolled in the study. The 24-48 h KIM-1 levels of the cases with exitus were higher (P = 0.007). The 24-48 h cystatin C and preoperative NGAL levels were higher in patients with postoperative AKI (P = 0.02). DISCUSSION: In newborns with CCHD, high KIM-1 levels may predict mortality, whereas high cystatin C and preoperative NGAL levels may be indicative of AKI. These biomarkers deserve further investigation in larger study populations.
RESUMO
BACKGROUND: Coarctation of the aorta is a common form of critical congenital heart disease that remains challenging to diagnose prior to clinical deterioration. Despite current screening methods, infants with coarctation may present with life-threatening cardiogenic shock requiring urgent hospitalization and intervention. We sought to improve critical congenital heart disease screening by using a novel pulse oximetry waveform analysis, specifically focused on detection of coarctation of the aorta. METHODS AND RESULTS: Over a 2-year period, we obtained pulse oximetry waveform data on 18 neonates with coarctation of the aorta and 18 age-matched controls hospitalized in the cardiac intensive care unit at Children's Healthcare of Atlanta. Patients with coarctation were receiving prostaglandin E1 and had a patent ductus arteriosus. By analyzing discrete features in the waveforms, we identified statistically significant differences in the maximum rate of fall between patients with and without coarctation. This was accentuated when comparing the difference between the upper and lower extremities, with the lower extremities having a shallow slope angle when a coarctation was present (p-value 0.001). Postoperatively, there were still differences in the maximum rate of fall between the repaired coarctation patients and controls; however, these differences normalized when compared with the same individual's upper vs. lower extremities. Coarctation patients compared to themselves (preoperatively and postoperatively), demonstrated waveform differences between upper and lower extremities that were significantly reduced after successful surgery (p-value 0.028). This screening algorithm had an accuracy of detection of 72% with 0.61 sensitivity and 0.94 specificity. CONCLUSIONS: We were able to identify specific features in pulse oximetry waveforms that were able to accurately identify patients with coarctation and further demonstrated that these changes normalized after surgical repair. Pulse oximetry screening for congenital heart disease in neonates may thus be improved by including waveform analysis, aiming to identify coarctation of the aorta prior to critical illness. Further large-scale testing is required to validate this screening model among patients in a newborn nursery setting who are low risk for having coarctation.

This study evaluates the effectiveness of mandatory pulse oximetry screening. The objective is to evaluate whether mandatory pulse oximetry testing had decreased the late critical congenital heart disease (CCHD) diagnosis rate and reduced mortality in neonatal subjects. This was a single center, retrospective cohort study comparing the timing of diagnosis of CCHD between neonates undergoing cardiac surgery in 2009-2010, prior to mandatory pulse oximetry screening, and neonates in 2015-2016, after mandatory pulse oximetry screening was instituted. Follow-up was for 1 year. We defined CCHD as lesions requiring surgical correction within 30 days of life. Exclusions included: pacemaker insertions, vascular ring divisions, closure of patent ductus arteriosus, arterial cutdown, or extracorporeal membrane oxygenation cannulation without structural heart disease as the sole procedure, or if subjects were born at home. Infants diagnosed prior to discharge from birth hospital were defined as early postnatal; late postnatal subjects were diagnosed after birth hospital discharge. In-hospital mortality and 1-year mortality were measured. A total of 527 neonates were included; 251 (47.6%) comprised the pre-mandatory pulse oximetry screening cohort (2009-2010). Only 3.6% of the 2009-2010 cohort and 4.3% of the 2015-2016 cohort were diagnosed late (p = 0.66). One-year mortality decreased during the study period (17.2% in 2009-2010 vs 10.5% in 2015-2016, p = 0.03). There were no deaths in the late CCHD diagnosis groups. Mandatory pulse oximetry screening legislation has not changed the late postnatal diagnosis rate at our institution. Mortality for neonatal CCHD has declined, but this decline is not attributable to mandatory pulse oximetry screening.

AIM: To determine the false-positive rate of pulse oximetry screening at moderate altitude, presumed to be elevated compared with sea level values and assess change in false-positive rate with time. METHODS: We retrospectively analysed 3548 infants in the newborn nursery in Albuquerque, New Mexico, (elevation 5400 ft) from July 2012 to October 2013. Universal pulse oximetry screening guidelines were employed after 24 hours of life but before discharge. Newborn babies between 36 and 36 6/7 weeks of gestation, weighing >2 kg and babies >37 weeks weighing >1.7 kg were included in the study. Log-binomial regression was used to assess change in the probability of false positives over time. RESULTS: Of the 3548 patients analysed, there was one true positive with a posteriorly-malaligned ventricular septal defect and an interrupted aortic arch. Of the 93 false positives, the mean pre- and post-ductal saturations were lower, 92 and 90%, respectively. The false-positive rate before April 2013 was 3.5% and after April 2013, decreased to 1.5%. There was a significant decrease in false-positive rate (p = 0.003, slope coefficient = -0.082, standard error of coefficient = 0.023) with the relative risk of a false positive decreasing at 0.92 (95% CI 0.88-0.97) per month. CONCLUSION: This is the first study in Albuquerque, New Mexico, reporting a high false-positive rate of 1.5% at moderate altitude at the end of the study in comparison to the false-positive rate of 0.035% at sea level. Implementation of the nationally recommended universal pulse oximetry screening was associated with a high false-positive rate in the initial period, thought to be from the combination of both learning curve and altitude. After the initial decline, it remained steadily elevated above sea level, indicating the dominant effect of moderate altitude.

INTRODUCTION: Congenital heart disease (CHD) is multifactorial in origin, resulting from an interaction between environmental and genetic factors. Multifactorial growth delay is common in infants with CHD. The impact of a genetic abnormality and CHD on the growth of an infant is lacking in the literature. The aim of this study is to compare the growth and method of feeding following neonatal cardiac surgery in infants with normal versus abnormal genetic testing. METHODS: A retrospective chart review of neonates who underwent a Risk Adjustment in Congenital Heart Surgery IV-VI procedure between 1 January, 2006 and 22 September, 2016 was performed at our institution. Weight, length, head circumference measurements, and feeding method were collected at birth, time of neonatal surgery, and monthly up to 6 months of age. RESULTS: A total of 53 infants met inclusion criteria, of which 22 had abnormal genetic testing. Approximately 90% of infants were discharged following neonatal cardiac surgery with supplemental tube feeds. At each monthly follow-up visit, more infants were exclusively fed orally: 80% of infants with normal genetics at 5 months post-operative follow-up versus 60% of infants with abnormal genetic testing, although statistically insignificant. Growth was not different among the two groups. CONCLUSIONS: Infants with critical CHD with or without genetic abnormalities are at risk for growth delays and many need supplemental tube feeds post-operatively and throughout follow-up. Infants with genetic abnormalities are slower to achieve oral feeds and more likely to require tube feedings. It is important to have a systematic protocol for managing these high-risk infants.

BACKGROUND: To investigate the feasibility of critical congenital heart disease (CCHD) screening test by pulse oximetry in four geographical regions of Turkey with different altitudes, before implementation of a nationwide screening program. METHODS: It was a prospective multi-centre study performed in four centres, between December, 2015 and May, 2017. Pre- and post-ductal oxygen saturations and perfusion indices (PI) were measured using Masimo Radical-7 at early postnatal days. The results were evaluated according to the algorithm recommended by the American Academy of Pediatrics. Additionally, a PI value <0.7 was accepted to be significant. RESULTS: In 4888 newborns, the mean screening time was 31.5 ± 12.1 hours. At first attempt, the mean values of pre- and post-ductal measurements were: saturation 97.3 ± 1.8%, PI 2.8 ± 2.0, versus saturation 97.7 ± 1.8%, PI 2.3±1.3, respectively. Pre-ductal saturations and PI and post-ductal saturations were the lowest in Centre 4 with the highest altitude. Overall test positivity rate was 0.85% (n = 42). CCHD was detected in six babies (0.12%). Of them, right hand (91 ± 6.3) and foot saturations (92.1 ± 4.3%) were lower compared to ones with non-CCHD and normal variants (p <0.05, for all comparisons). Sensitivity, specificity, positive and negative predictive values, and likelihood ratio of the test were: 83.3%, 99.9%, 11.9%, 99.9%, and 99.2%, respectively. CONCLUSION: This study concluded that pulse oximetry screening is an effective screening tool for congenital heart disease in newborns at different altitudes. We support the implementation of a national screening program with consideration of altitude differences for our country.

BACKGROUND: Delayed diagnosis of critical congenital heart disease (CCHD) carries a serious risk of mortality, morbidity, and handicap. As echocardiography is commonly used to diagnose congenital heart disease (CHD), echocardiographic investigations in newborns may be helpful in detecting CCHD earlier and with higher sensitivity than when using other screening methods. The present study aimed to evaluate the effectiveness of echocardiographic screening for CCHD in a tertiary care center. METHODS: A retrospective chart review was conducted among newborns delivered at Hamamatsu University Hospital between June 2009 and May 2016. The study included consecutive newborns who underwent early echocardiographic screening (within the first 5 days of life) performed by pediatric cardiologists, were born at ≥36 weeks of gestation, had a birthweight ≥2300 g, and were cared for in the well-baby nursery. Newborns admitted to the neonatal intensive care unit, as well as those with prenatal diagnosis of CHD and/or clinical symptoms or signs of CHD were excluded. Four CHD outcome categories were defined: critical, serious, clinically significant, and clinically non-significant. RESULTS: A total of 4082 live newborns were delivered during the study period. Of 3434 newborns who met the inclusion criteria and had complete echocardiography data, 104 (3.0%) were diagnosed as having CHD. Among these, none was initially diagnosed as having critical or serious CHD. Of the 95 newborns who continued follow-up with a cardiologist, 61 (64%) were determined to have non-significant CHDs that resolved within 6 months of life. Review of excluded newborns revealed nine cases of critical or serious CHD; among these newborns, six were diagnosed prenatally and three had some clinical signs of CHD prior to hospital discharge. CONCLUSIONS: In our tertiary care center, echocardiography screening within the first 5 days of life did not help improve CCHD detection rate in newborns without prenatal diagnosis or clinical signs of CHD. Echocardiographic screening may be associated with increased rate of false-positives (defects resulting in clinically non-significant CHDs) in newborns without prenatal diagnosis or suspicion of CHD.
