Abstract
Congenital heart disease (CHD) is the most prevalent hereditary disorder, affecting approximately 1% of all live births. A reduction in morbidity and mortality has been achieved with advancements in surgical intervention, yet challenges in managing complications, extracardiac abnormalities, and comorbidities still exist. To address these, a more comprehensive understanding of the genetic basis underlying CHD is required to establish how certain variants are associated with the clinical outcomes. This will enable clinicians to provide personalized treatments by predicting the risk and prognosis, which might improve the therapeutic results and the patient's quality of life. We review how advancements in genome sequencing are changing our understanding of the genetic basis of CHD, discuss experimental approaches to determine the significance of novel variants, and identify barriers to use this knowledge in the clinics. Next-generation sequencing technologies are unravelling the role of oligogenic inheritance, epigenetic modification, genetic mosaicism, and noncoding variants in controlling the expression of candidate CHD-associated genes. However, clinical risk prediction based on these factors remains challenging. Therefore, studies involving human-induced pluripotent stem cells and single-cell sequencing help create preclinical frameworks for determining the significance of novel genetic variants. Clinicians should be aware of the benefits and implications of the responsible use of genomics. To facilitate and accelerate the clinical integration of these novel technologies, clinicians should actively engage in the latest scientific and technical developments to provide better, more personalized management plans for patients.

Abstract
Introduction Noncardiac anomalies (NCAs) in patients with congenital heart defects (CHDs) are crucial for perioperative management and etiology studies. This study aimed to investigate NCAs in Chinese children with CHDs. Methods Medical records for CHD-diagnosed children hospitalized from 1 January 2015 to 31 December 2019 were collected and subjected to retrospective analyses to excavate potential association rules between CHDs and noncardiac malformations. Results A total of 3,788 CHD patients were included in this study. The main phenotypes of CHD were Ventricular Septal Defect (VSD, 33.69%), Atrial Septal Defect (ASD, 12.72%), and Tetralogy of Fallot (TOF, 5.54%). A total of 887 (23.42%) cases showed noncardiac anomalies, which were mainly associated with the central nervous system (34.61%), nose/ear/mandibular/face (19.39%), genitourinary system (15.78%), and musculoskeletal system (15.56%). Compared to other CHD subtypes, septal defects had a lower percentage of associated NCAs (P = 3.7 × 10-9) while AVSD had a higher percentage (P = 0.0018). Disscussion NCAs are prevalent among CHD-diagnosed children in China, and the spectrums of NCAs in different CHD subcategories were different.

Protecting brains and saving futures guidelines: A prospective, multicenter, and observational study on the use of telemedicine for neonatal neurocritical care in Brazil. PLoS One 2022; 17:e0262581. [PMID: 35020756 PMCID: PMC8754327 DOI: 10.1371/journal.pone.0262581] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/14/2021] [Accepted: 12/29/2021] [Indexed: 11/19/2022] Open
Abstract
Background
Management of high-risk newborns should involve the use of standardized protocols and training, continuous and specialized brain monitoring with electroencephalography (EEG), amplitude integrated EEG, Near Infrared Spectroscopy, and neuroimaging. Brazil is a large country with disparities in health care assessment and some neonatal intensive care units (NICUs) are not well structured with trained personnel able to provide adequate neurocritical care. To reduce this existing gap, an advanced telemedicine model of neurocritical care called Protecting Brains and Saving Futures (PBSF) Guidelines was developed and implemented in a group of Brazilian NICUs.
Methods
A prospective, multicenter, and observational study will be conducted in all 20 Brazilian NICUs using the PBSF Guidelines as standard-of-care. All infants treated accordingly to the guidelines during Dec 2021 to Nov 2024 will be eligible. Ethical approval was obtained from participating centers. The primary objective is to describe adherence to the PBSF Guidelines and clinical outcomes, by center and over a 3-year period. Adherence will be measured by quantification of neuromonitoring, neuroimaging exams, sub-specialties consultation, and clinical case discussions and videoconference meetings. Clinical outcomes of interest are detection of seizures during hospitalization, use of anticonvulsants, inotropes, and fluid resuscitation, death before hospital discharge, length of hospital stay, and referral of patients to specialized follow-up.
Discussion
The study will provide evaluation of PBSF Guidelines adherence and its impact on clinical outcomes. Thus, data from this large prospective, multicenter, and observational study will help determine whether neonatal neurocritical care via telemedicine can be effective. Ultimately, it may offer the necessary framework for larger scale implementation and development of research projects using remote neuromonitoring.

Abstract
Congenital heart defects (CHDs) are the most common birth defects (BDs) and account for nearly one-third of all BDs. The aim of this article was to investigate the epidemiology and major subtypes of CHDs in Hunan Province, China in the last 5 years.CHD surveillance data from 2012 to 2016 were collected from 52 registered hospitals in Hunan. The prevalence rates of CHDs, incidence rates of CHDs combined with other BDs, and rates of termination of pregnancy (TOP) for CHDs among different regions, infant sexes, and maternal ages were calculated for both early fetuses (<28 weeks of gestation) and perinatal infants (PIs) (between 28 weeks of gestation and 7 days after birth). Both the constituent ratio and prevalence rates were computed among subtypes.CHDs were found in 6289 out of 673,060 births. The overall prevalence was 93.44 per 10,000 PIs, with 19.27 and 74.17 per 10,000 in early fetuses and PIs, respectively. The risks of CHDs were higher in infants from urban areas than those from rural areas during the whole gestation and were higher in male infants than in female infants during the perinatal period. The total prevalence of CHDs increased significantly with maternal age (χ trend = 141.84, P < .05). Among fetuses in early gestation, there were 288 cases (22.21%) of CHDs combined with other BDs and 1292 cases (99.61%) of TOP for CHD. The 3 major subtypes of CHDs were ventricular septal defect (VSD) (22.06%), Tetralogy of Fallot (TOF) (9.43%), and atrioventricular septal defect (AVSD) (6.69%). Among PIs, there were 1541 cases (30.87%) of CHD diagnosed before delivery and 1184 cases (76.83%) were TOP. The 3 major subtypes were atrial septal defect (ASD) (42.81%), patent ductus arteriosus (PDA) (16.07%), and VSDs (15.21%).The total prevalence of CHD in Hunan Province and the rate of TOP for CHD was high, especially for early-gestation fetuses. Pregnancies in urban women, male PIs, and maternal age were the risk factors for CHDs. Among early-gestation fetuses, the most common types were VSD, TOF, and ASD, and among PIs, the most common types were ASD, PDA, and VSD.

Abstract
Introducción. Las cardiopatías congénitas son alteraciones estructurales y funcionales del corazón, sistema circulatorio y grandes vasos que se desarrollan durante la embriogénesis cardiaca. A nivel mundial dichos defectos son una causa importante de morbi-mortalidad en la población infantil.Objetivo. Determinar la prevalencia de cardiopatías congénitas en la ciudad de Bogotá, durante el periodo de 2001 a 2014 y evaluar la tendencia en el tiempo.Material y métodos. Se analizaron 405.408 recién nacidos del Programa de Vigilancia y Seguimiento de Niños con Anomalías Congénitas de la Secretaría de Salud de Bogotá calculando la prevalencia de las cardiopatías congénitas a través de un registro diario de nacimientos y su evaluación clínica y paraclínica. Se clasificaron en aisladas, complejas y asociada y se halló la prevalencia por año. Se evaluó la mortalidad en las primeras horas de vida.Resultados. La prevalencia de cardiopatías congénitas fue de 15,1 por cada 10.000 recién nacidos en todo el período, pero se evidenciaron valores por encima de 20x10.000 en los últimos 3 años. Del total, 46% fueron de sexo femenino, 53,16% de sexo masculino y 0.33% indeterminado. De los nacidos malformados, 397 cardiopatías fueron aisladas, 142 asociadas a otras malformaciones extracardiacas y 74 complejas.Conclusiones. Las cardiopatías tienen gran impacto en la salud de la población infantil y aunque la prevalencia es menor que en otros países, esto puede deberse a subregistro a nivel nacional. Se nota un aumento en la prevalencia en los últimos 3 años que puede corresponder a la implementación de los programas de vigilancia nacional y local. Sugerimos continuar el desarrollo de programas que incrementen e incentiven el tamizaje y registro de estas patologías.

Abstract
In 2011 and 2012, the Division of Microbiology and Infectious Diseases at the National Institute of Allergy and Infectious Diseases, National Institutes of Health, held a series of meetings to provide guidance to investigators regarding study design of clinical trials of vaccines and antimicrobial medications that enroll pregnant women. Assessment of congenital anomalies among infants born to women enrolled in these trials was recognized as a challenging issue, and a workgroup with expertise in epidemiology, pediatrics, genetics, dysmorphology, clinical trials, and infectious diseases was formed to address this issue. The workgroup considered 3 approaches for congenital anomalies assessment that have been developed for use in other studies: (1) maternal report combined with medical records review, (2) standardized photographic assessment and physical examination by a health professional who has received specific training in congenital anomalies, and (3) standardized physical examination by a trained dysmorphologist (combined with maternal interview and medical records review). The strengths and limitations of these approaches were discussed with regard to their use in clinical trials. None of the approaches was deemed appropriate for use in all clinical trials. Instead, the workgroup acknowledged that decisions regarding the optimal method of assessment of congenital anomalies will likely vary depending on the clinical trial, its setting, and the agent under study; in some cases, a combination of approaches may be appropriate. The workgroup recognized the need for more research on approaches to the assessment of congenital anomalies to better guide investigators in optimal design of clinical trials that enroll pregnant women.

Abstract
OBJECTIVE This study was designed to estimate the birth prevalence of children with congenital heart disease born in the Gaza Strip during 2010 and to compare these with estimates from elsewhere. METHODS We reviewed the medical records of all children born in 2010 who were diagnosed, treated, and/or followed up in the four paediatric cardiology clinics in the Gaza Strip. Data were also obtained from El Makassed Hospital in East Jerusalem and from the Schneider Hospital, Wolfson Medical Center, and Tel HaShomer Hospital in Israel, where we had referred some of our patients for percutaneous or surgical treatment. RESULTS A total of 598 children with congenital heart disease were detected among the 59,757 children born alive in the Gaza Strip during 2010, yielding a birth incidence of 10 per 1000 live births. The most frequently occurring conditions were ventricular septal defects (28%), ostium secundum atrial septal defects (17%), patent ductus arteriosus (8.5%), and pulmonary valve abnormalities (8%). In this study, 7% of the children died. The actuarial survival at 6 months and 1 year of age was 94% and 93%, respectively, and remained stable over 18 months of follow-up. CONCLUSION The birth incidence of congenital heart disease in the Gaza Strip in 2010 (10 per 1000) is higher than most estimates in Western Europe (8.2 per 1000 live births) and North America (6.9 per 1000 live births) but is similar to estimates from other parts of Asia (9.3 per 1000 live births).

Abstract
AIM To investigate the previously unknown birth incidence, treatment, and mortality of children with congenital heart disease in Tunisia. METHODS We undertook a retrospective review of medical records of all patients who were born in 2010 and 2011, and were diagnosed in Sfax (Tunisia) with congenital heart defect. RESULTS Among 37,294 births, 255 children were detected to have congenital heart disease, yielding a birth incidence of 6.8 per 1000. The most frequently occurring conditions were ventricular septal defects (31%), ostium secundum atrial septal defects (12.9%), and pulmonary valve abnormalities (12%). Coarctation of the aorta, tetralogy of Fallot, univentricular physiology, pulmonary atresia with ventricular septal defect, and transposition of the great arteries were found in 4.3%, 6.2%, 3.4%, 2.7%, and 2.7%, respectively. During the follow-up of 1 year, 23% of the children died. About three-quarters of those deaths happened before surgery. CONCLUSION The present study is in line with the general estimates in the world. It has revealed a high case of mortality among the patients awaiting corrective surgery. These children need more facilities.

Abstract
OBJECTIVE To review the association between congenital heart defects and extracardiac malformations. DATA SOURCES Scientific articles were searched in the Medline, Lilacs, and SciELO databases, using the descriptors "congenital heart disease," "congenital heart defects," "congenital cardiac malformations," "extracardiac defects," and "extracardiac malformations." All case series that specifically explored the association between congenital heart defects and extracardiac malformations were included. DATA SYNTHESIS Congenital heart diseases are responsible for about 40% of birth defects, being one of the most common and severe malformations. Extracardiac malformations are observed in 7 to 50% of the patients with congenital heart disease, bringing a greater risk of comorbidity and mortality and increasing the risks related to heart surgery. Different studies have attempted to assess the presence of extracardiac abnormalities in patients with congenital heart disease. Among the changes described, those of the urinary tract are more often reported. However, no study has evaluated all patients in the same way. CONCLUSIONS Extracardiac abnormalities are frequent among patients with congenital heart disease, and patients with these alterations may present an increased risk of morbimortality. Therefore, some authors have been discussing the importance and cost-effectiveness of screening these children for other malformations by complementary exams.

Abstract
Background Chromosomal abnormalities (CAs) are an important cause of congenital heart disease
(CHD). Objective Determine the frequency, types and clinical characteristics of CAs identified in a
sample of prospective and consecutive patients with CHD. Method Our sample consisted of patients with CHD evaluated during their first
hospitalization in a cardiac intensive care unit of a pediatric referral hospital
in Southern Brazil. All patients underwent clinical and cytogenetic assessment
through high-resolution karyotype. CHDs were classified according to Botto et al.
Chi-square, Fisher exact test and odds ratio were used in the statistical analysis
(p < 0.05). Results Our sample consisted of 298 patients, 53.4% males, with age ranging from 1 day to
14 years. CAs were observed in 50 patients (16.8%), and 49 of them were syndromic.
As for the CAs, 44 (88%) were numeric (40 patients with +21, 2 with +18, 1 with
triple X and one with 45,X) and 6 (12%) structural [2 patients with der(14,21),
+21, 1 with i(21q), 1 with dup(17p), 1 with del(6p) and 1 with add(18p)]. The
group of CHDs more often associated with CAs was atrioventricular septal defect. Conclusions CAs detected through karyotyping are frequent in patients with CHD. Thus,
professionals, especially those working in Pediatric Cardiology Services, must be
aware of the implications that performing the karyotype can bring to the
diagnosis, treatment and prognosis and for genetic counseling of patients and
families.

Abstract
OBJECTIVES To examine trends in the prevalence of congenital heart defects (CHDs) in Europe and to compare these trends with the recent decrease in the prevalence of CHDs in Canada (Quebec) that was attributed to the policy of mandatory folic acid fortification. STUDY DESIGN We used data for the period 1990-2007 for 47 508 cases of CHD not associated with a chromosomal anomaly from 29 population-based European Surveillance of Congenital Anomalies registries in 16 countries covering 7.3 million births. We estimated trends for all CHDs combined and separately for 3 severity groups using random-effects Poisson regression models with splines. RESULTS We found that the total prevalence of CHDs increased during the 1990s and the early 2000s until 2004 and decreased thereafter. We found essentially no trend in total prevalence of the most severe group (group I), whereas the prevalence of severity group II increased until about 2000 and decreased thereafter. Trends for severity group III (the most prevalent group) paralleled those for all CHDs combined. CONCLUSIONS The prevalence of CHDs decreased in recent years in Europe in the absence of a policy for mandatory folic acid fortification. One possible explanation for this decrease may be an as-yet-undocumented increase in folic acid intake of women in Europe following recommendations for folic acid supplementation and/or voluntary fortification. However, alternative hypotheses, including reductions in risk factors of CHDs (eg, maternal smoking) and improved management of maternal chronic health conditions (eg, diabetes), must also be considered for explaining the observed decrease in the prevalence of CHDs in Europe or elsewhere.

Abstract
We aimed to assess the frequency of chromosomal abnormalities among infants with congenital heart defects (CHDs) in an analysis of population-based surveillance data. We reviewed data from the Metropolitan Atlanta Congenital Defects Program, a population-based birth-defects surveillance system, to assess the frequency of chromosomal abnormalities among live-born infants and fetal deaths with CHDs delivered from January 1, 1994, to December 31, 2005. Among 4430 infants with CHDs, 547 (12.3%) had a chromosomal abnormality. CHDs most likely to be associated with a chromosomal abnormality were interrupted aortic arch (type B and not otherwise specified; 69.2%), atrioventricular septal defect (67.2%), and double-outlet right ventricle (33.3%). The most common chromosomal abnormalities observed were trisomy 21 (52.8%), trisomy 18 (12.8%), 22q11.2 deletion (12.2%), and trisomy 13 (5.7%). In conclusion, in our study, approximately 1 in 8 infants with a CHD had a chromosomal abnormality. Clinicians should have a low threshold at which to obtain testing for chromosomal abnormalities in infants with CHDs, especially those with certain types of CHDs. Use of new technologies that have become recently available (e.g., chromosomal microarray) may increase the identified contribution of chromosomal abnormalities even further.

Abstract
BACKGROUND The pre- and postnatal detection rate, incidence, clinical characteristics and outcomes of congenital heart disease (CHD) have been studied in developed countries for many years, but rarely have large-scale studies been reported in Chinese populations. The aim of the present study was to investigate the pre- and postnatal detection rates, incidence, clinical characteristics and outcomes of CHD in a Chinese hospital in order to improve the future screening and treatment of CHD. METHODS Fetuses without risk factors for CHD were screened using basic cardiac ultrasound examination (BCUE). Fetuses with suspected cardiac malformation revealed by BCUE and fetuses with risk factors were screened using extended cardiac ultrasound examination. Outcomes recorded from fetal, neonatal and postmortem records over 4 years (2006-2009) included: therapeutic termination of pregnancy, spontaneous abortions or stillbirths, deaths at birth or in the neonatal period (before 28 days of age), and rate of birth and clinical characteristics of newborns. RESULTS A total of 34,071 fetuses were screened for CHD during a period of 4 years, of which 173 fetuses were screened for CHD using BCUE and 301 fetuses were screened using extended cardiac ultrasound examination. The incidence of fetal CHD increased from 1.1% in 2006 to 2.4% in 2009 (P < 0.05), yielding an overall incidence of 1.5% (523/34,071). Of the fetuses with CHD, 48.2% (252/523) died before 28 days of age (including intra-uterine death and termination of pregnancy), 51.8% (271/523) lived more than 28 days and the incidence of live newborns with CHD was 0.80% (271/34071). CONCLUSIONS The prevalence of CHD was quite common in this Chinese hospital. Detailed profiles of CHD suggest that, while training programs in obstetric screening at this hospital were beneficial, prenatal intervention, treatment and care of fetal CHD were inefficient and should be strengthened in China.

Abstract
OBJECTIVES The purpose of this study was to estimate the prevalence of major and minor congenital heart defects among fetuses and neonates using sonography in a general population of 4 areas surrounding Shanghai, China. METHODS Pregnant women were recruited between April 2004 and December 2005 in Jiaxing City, Suzhou City, Changshu County, and Haining County. All participants could have 3 sonographic examinations performed by specially trained physicians regardless of medical indication: a fetal sonographic screen and fetal echocardiography between 20 and 28 weeks' gestation and neonatal echocardiography. Diagnoses of congenital heart defects were made on the basis of review of all available scans by an international group of experts in pediatric cardiology. Prevalence rates were calculated per 1000 births. RESULTS Among 4006 scanned fetuses and neonates, there were 75 congenital heart defects, including 12 major defects. The observed prevalence for all congenital heart defects was 18.7 (95% confidence interval, 14.8-23.5) per 1000 births, and the prevalence for major defects was 3.0 (95% confidence interval, 1.6-5.2) per 1000 births. The most common defects were ventricular septal defects (n = 47 [62.7%]), atrial septal defects (n = 14 [18.7%]), tetralogy of Fallot (n = 4 [5.3%]), and hypoplastic left heart syndrome (n = 3 [4.0%]). CONCLUSIONS The prevalence of all congenital heart defects in the 4 areas of China studied was higher than that reported in other countries, with ventricular septal defects being the most frequent defects. Our data likely reflect a better estimate of the total prevalence of congenital heart defects in China than reported previously.

Abstract
OBJECTIVE To identify the proportion of major structural noncardiac anomalies identified with congenital heart defects (CHDs). STUDY DESIGN Records of infants with CHDs in the Metropolitan Atlanta Congenital Defects Program who were born during the period 1968 through 2005 were classified as having isolated, syndromic, multiple CHD (ie, having an unrecognized pattern of multiple congenital anomalies or a recognized pattern of multiple congenital anomalies of unknown etiology), or laterality defects. Frequencies of associated noncardiac anomalies were obtained. RESULTS We identified 7984 live-born and stillborn infants and fetuses with CHDs. Among them, 5695 (71.3%) had isolated, 1080 (13.5%) had multiple, 1048 (13.1%) had syndromic, and 161 (2.0%) had laterality defects. The percentage of multiple congenital anomalies was highest for case with atrial septal defects (18.5%), cardiac looping defects (17.2%), and conotruncal defects (16.0%), and cases with atrioventricular septal defects represented the highest percentages of those with syndromic CHDs (66.7%). CONCLUSIONS Including those with syndromes and laterality defects, 28.7% of case infants with CHDs had associated major noncardiac malformations. Thus, infants with CHDs warrant careful examination for the presence of noncardiac anomalies.

Abstract
Background—
This study determines the prevalence of Congenital Heart Defects (CHD), diagnosed prenatally or in infancy, and fetal and perinatal mortality associated with CHD in Europe.
Methods and Results—
Data were extracted from the European Surveillance of Congenital Anomalies central database for 29 population-based congenital anomaly registries in 16 European countries covering 3.3 million births during the period 2000 to 2005. CHD cases (n=26 598) comprised live births, fetal deaths from 20 weeks gestation, and terminations of pregnancy for fetal anomaly (TOPFA). The average total prevalence of CHD was 8.0 per 1000 births, and live birth prevalence was 7.2 per 1000 births, varying between countries. The total prevalence of nonchromosomal CHD was 7.0 per 1000 births, of which 3.6% were perinatal deaths, 20% prenatally diagnosed, and 5.6% TOPFA. Severe nonchromosomal CHD (ie, excluding ventricular septal defects, atrial septal defects, and pulmonary valve stenosis) occurred in 2.0 per 1000 births, of which 8.1% were perinatal deaths, 40% were prenatally diagnosed, and 14% were TOPFA (TOPFA range between countries 0% to 32%). Live-born CHD associated with Down syndrome occurred in 0.5 per 1000 births, with >4-fold variation between countries.
Conclusion—
Annually in the European Union, we estimate 36 000 children are live born with CHD and 3000 who are diagnosed with CHD die as a TOFPA, late fetal death, or early neonatal death. Investing in primary prevention and pathogenetic research is essential to reduce this burden, as well as continuing to improve cardiac services from in utero to adulthood.

Abstract
OBJECTIVE To characterize serious congenital heart disease in very low birth weight (VLBW) infants (born at <1500 g or a gestational age of 22-29 weeks) in a large, international database. PATIENTS AND METHODS We analyzed a database of 99 786 VLBW infants born or treated at 703 NICUs between calendar years 2006 and 2007. We defined serious congenital heart disease as 1 of 14 specific lesions or any other structural congenital heart disease that required surgical or medical treatment by initial hospital discharge or by the age of 1 year. We reviewed records for all infants with cardiac diagnoses and other genetic syndromes and associations to determine which had serious congenital heart disease. We excluded nonstructural disease as well as isolated and untreated atrial or ventricular septal defects. We determined the frequency of serious congenital heart disease, compared overall mortality rates of those with and without serious congenital heart disease, and determined the distribution of specific lesions and mortality for each diagnosis. RESULTS Of 99 786 VLBW infants studied, 893 had serious congenital heart disease (8.9 per 1000). The most common lesions were tetralogy of Fallot (n = 166 [18.6% of those with serious congenital heart disease]), aortic coarctation (n = 103 [11.5%]), complete atrioventricular canal (n = 81 [9.1%]), pulmonary atresia (n = 73 [8.2%]), and double-outlet right ventricle (n = 68 [7.6%]). The mortality rate of those with serious congenital heart disease was 44%, compared with 12.7% in those without serious congenital heart disease (P < .0001). CONCLUSIONS Serious congenital heart disease is probably more frequent in VLBW infants treated in NICUs than in the general live-born population, and the distribution reflects lesions associated with extracardiac malformations. VLBW infants with serious congenital heart disease have higher a mortality rate than those without, independent of other risk factors.

Abstract
OBJECTIVES To investigate the prevalence at live birth of congenital heart disease (CHD) in Taiwan. STUDY DESIGN Patients with CHD born from 2000 to 2006 were identified from National Health Insurance databases. RESULTS CHD prevalence was 13.08 per 1000 live births: 12.05 (simple, 10.53; severe, 1.51) in male infants and 14.21 (simple, 12.90; severe, 1.32) in female infants. Ventricular septal defect (VSD; 4.0) was the most common defect, followed by secundum atrial septal defect (ASDII; 3.2), patent ductus arteriosus (PDA; 2.0), pulmonary stenosis (PS; 1.2), tetralogy of Fallot (TOF; 0.63), coarctation of aorta (CoA; 0.25), transposition of great arteries (TGA; 0.21), endocardial cushion defect (ECD; 0.20), double outlet of right ventricle (DORV; 0.15), total anomalous pulmonary venous return (TAPVR; 0.11), aortic stenosis (0.09), hypoplastic left heart syndrome (HLHS; 0.062), Ebstein anomaly (0.047), and tricuspid atresia (0.046). Female predominance was observed in VSD, ASDII, PDA, and ECD; and male predominance was observed in TGA and TOF. Ratios of western prevalence to our Asian prevalence were high for HLHS (3.68-4.5), CoA (1.13-1.96), TGA (1.09-1.83), and tricuspid atresia (1.09-2.57), but low for PS (0.15-0.99), TOF (0.41-0.92), and possibly ASDII. CONCLUSIONS In this Asian population, the prevalence of CHD was at the high end of the reported range, with more PS and TOF, but fewer left-sided obstructions, TGA, and tricuspid atresia.

Abstract
BACKGROUND Time trends in congenital heart defects (CHD) by specific phenotype and with long follow-up time are rarely available for an entire population. We present trends in national CHD prevalences over the past 3 decades. METHODS We linked information from the National Patient Register, the Causes of Death Register, and the Danish Cytogenetic Central Register for all persons born in Denmark, 1977 to 2005, and registered in the Civil Registration System, yielding a cohort of 1,763,591 persons-18,207 with CHD. Individuals with CHDs were classified by phenotype (heterotaxia, conotruncal defect, atrioventricular septal defect, anomalous pulmonary venous return, left and right ventricular outflow tract obstructions, septal defects, complex defects, associations, patent ductus arteriosus, unspecified, and other specified) by combining International Classification of Diseases codes using a hierarchical approach. RESULTS From 1977 to 2005, the overall CHD birth prevalence increased from 73 to 113 per 10,000 live births. Generally, prevalence increased for defects diagnosed in infancy, until 1996-1997, and then stabilized. For each 5-year interval, isolated septal defects and severe defects increased by 22% (95% CI, 20%-25%) and 5% (95% CI, 4%-7%), respectively. Among the severe defects, conotruncal defects and atrioventricular septal defect showed the largest prevalence increases. Women had a lower prevalence of severe defects during the 1980s. The CHD prevalence increase was unchanged when persons with extracardiac defects or chromosomal aberrations were excluded. CONCLUSIONS CHD birth prevalence increased from the beginning of the 1980s but stabilized in the late 1990s.

Abstract
AIM To investigate the birth prevalence, treatment modalities and short-term survival of children with congenital heart disease who were born in 2002. METHODS We undertook a retrospective review of medical records of all patients who were born in 2002, and were diagnosed, treated and/or followed-up in one of the seven-paediatric cardiology programmes in Belgium. RESULTS In 111 225 births, 921 children with congenital heart disease were detected, yielding a birth prevalence of 8.3 per 1000. The most frequently occurring conditions were ventricular septal defects (VSDs) (33%), ostium secundum atrial septal defects (18%) and pulmonary valve abnormalities (10%). Thirty-nine percent of the children either had a cardiosurgical operation or catheter intervention. In this study, 4% of the children died. The actuarial survival at 6 months and 1 year of age was 97% and 96%, respectively and remained stable after then. Compared to other heart defects, mortality was higher in univentricular physiology, pulmonary atresia with VSD, left ventricle outflow obstruction and tetralogy of Fallot. CONCLUSION Survival of congenital heart disease is excellent and continued to improve in the early 21st century. New therapeutic options are increasingly used. This study provides baseline data for the longitudinal follow-up of this cohort.

Abstract
Congenital heart disease (CHD) is the most prevalent group of congenital anomalies. There is considerable variation in the reported epidemiology of CHD, mainly attributable to methodological differences. Using register-based data, the current study describes the epidemiology of CHD in a geographically well-defined population of the North of England during 1985-2003. The total prevalence of CHD was 85.9 per 10 000 births and terminations of pregnancy for fetal anomaly. Livebirth prevalence was 79.7 per 10 000 livebirths. Both total and livebirth prevalence increased during the study period. Ninety-two per cent of affected pregnancies resulted in a livebirth, 5% were terminated, 2% resulted in a stillbirth, and 1% in a late miscarriage. Almost a quarter (23%) of cases had one or more coincident anomalies of other organs, with chromosomal abnormalities the most frequent group. A total of 89.2% of cases survived to 1 year and the survival improved during the study period. This population-based study has demonstrated an increasing trend in both prevalence and survival among children with CHD.

Abstract
OBJECTIVES With this study we aimed to compare survival rates for children with Down syndrome in 2 time periods, 1 before prenatal screening (1988-1990) and 1 contemporaneous with screening (1998-2000), and to examine the frequency of comorbidities and their influence on survival rates. METHODS Record-linkage was performed between the population-based Victorian Birth Defects Register and records of deaths in children up to 15 years of age collected under the auspice of the Consultative Council on Obstetric and Pediatric Mortality and Morbidity. Cases of Down syndrome were coded according to the presence or absence of comorbidities by using the International Classification of Diseases, Ninth Revision classification of birth defects. Kaplan-Meier survival functions and log rank tests for equality of survival distributions were performed. RESULTS Of infants liveborn with Down syndrome in 1998-2000, 90% survived to 5 years of age, compared with 86% in the earlier cohort. With fetal deaths excluded, the proportion of isolated Down syndrome cases in the earlier cohort was 48.7% compared with 46.1% in the most recent cohort. In 1988-1990 there was at least 1 cardiac defect in 41.1% of cases and in 45.4% in 1998-2000. There was significant variation in survival rates for the different comorbidity groupings in the 1988-1990 cohort, but this was not so evident in the 1998-2000 cohort. CONCLUSIONS Survival of children with Down syndrome continues to improve, and there is an overall survival figure of 90% to at least 5 years of age. It is clear from this study that prenatal screening technologies are not differentially ascertaining fetuses with Down syndrome and additional defects, because there has been no proportional increase in births of isolated cases with Down syndrome.

Abstract
The co-occurrence of congenital diaphragmatic hernia (CDH) and cardiovascular malformations (CVMs) has important clinical, genetic, and developmental implications. Previous examinations of this topic often included patients with genetic syndromes. To correct this potential bias, we undertook an extensive review of the literature and obtained new data. The frequency of CVMs associated with isolated CDH was 11-15%. A careful analysis of CVMs indicates that atrial and ventricular septal defects, conotruncal defects, and left ventricular outflow tract obstructive defects were the most common type of CVMs, but proportional to the frequency of occurrence in the general population. The combination of CVM and CDH results in a poorer prognosis than would be expected with either malformation alone. However, the impact on survival from patients with a genetic syndrome has not been consistently evaluated. We encourage researchers to re-analyze existing series and recommend that future studies distinguish isolated CDH from that which is associated with other malformations, especially as part of genetic syndromes. Therapies should be tailored to maximize cardiac output and systemic oxygen delivery rather than systemic oxygen saturation alone. Although there is speculation about the frequency with which isolated left ventricular "hypoplasia" occurs in patients with CDH, we suggest it results from compression of a pre-load deficient left ventricle by the hypertensive right ventricle, and unlike true hypoplasia, is reversible. Irrespective of the type of severity of CVMs in patients with CDH, the degree of pulmonary hypoplasia and pulmonary vascular disease predicts outcome.

Abstract
BACKGROUND As part of an effort to validate the General Practice Research Database (GPRD) for future studies of medication use in pregnancy, this study examined whether the rates of all, and specific types of, congenital heart defects obtained from the GPRD are similar to those obtained from UK national systems. METHODS The prevalence rates of heart defects for 2001-2003 were determined from the GPRD and compared with both the National Congenital Anomaly System (NCAS) and the European Concerted Action of Congenital Anomalies and Twins (EUROCAT). Rate ratios (RRs) and 95% CIs were calculated comparing the prevalence of all congenital heart defects as well as specific types of heart defects in the three data sources. In addition, the effect of the child's age on the frequency of heart defects in the GPRD was determined. RESULTS The prevalence of heart defects in the GPRD was more than twice as high as in the NCAS and slightly higher than in the EUROCAT. All differences were statistically significant. The prevalence of specific heart defects varied across the GPRD, NCAS, and EUROCAT. The measured prevalence of congenital heart defects in the GPRD was higher if calculated including children up to age 6. CONCLUSIONS The comparisons of the GPRD prevalence rates to national prevalence estimates demonstrate that the GPRD can serve as a more complete source of background prevalence for the most commonly occurring congenital heart defects, which is essential to properly assess possible associations between maternal exposures and congenital heart defects.

Abstract
Few known monogenic causes of non-syndromic congenital heart disease (CHD) have been identified. Mutations in NKX2.5 were initially implicated in familial cases of cardiac septal defects and subsequently, functionally significant NKX2.5 mutations were found in diverse forms of non-syndromic CHD. Similarly, mutations in GATA4, which encodes a cardiac transcription factor, were first identified in familial cases of cardiac septal defects. We hypothesize that individuals with non-syndromic CHD may harbor GATA4 mutations and that these mutations alter the biochemical properties of the protein. The coding region encompassing the six exons of GATA4 was screened in a study population of 157 patients with CHD. We identified several sequence variations in GATA4. We tested these novel sequence variations that altered evolutionarily conserved amino acids and other previously reported GATA4 mutations in various biochemical assays. The novel sequence variations had no biochemical deficits while a previously reported, but unstudied, missense mutation in GATA4 (S52F) functioned as a hypomorph in transactivation assays. We did not identify any novel GATA4 mutations in our patient population with non-syndromic CHD. Consistent with previous findings, GATA4 mutations that result in deficits in transactivation ability are consistently associated with CHD suggesting that normal transactivation properties of GATA4 are required for proper cardiac development.

Abstract
OBJECTIVES This study aimed to characterize the prevalence of congenital heart disease (CHD) in children born alive in São Miguel island from January 1992 to December 2001. METHODS Based on the Azorean Registry of CHD, which includes complete clinical and personal information, 189 patients were diagnosed. RESULTS During this 10-year period, the average prevalence of CHD is 9.16 per 1,000 live births (range 4.77-12.75). The most frequent cardiac malformations found were: ventricular septal defect (38.1%), atrial septal defect (12.2%) and patent ductus arteriosus (11.6%). Until now, four familial clusters were identified, representing a total of 13 patients. CONCLUSIONS This first epidemiological study of CHD in the Azorean population reveals evidence for familial aggregation, which is of great interest for understanding the genes involved in these complex pathologies.

Abstract
OBJECTIVE To examine population-based overall and malformation-specific trends in the prenatal diagnosis, pregnancy termination, and perinatal mortality for congenital heart disease (CHD) during a period of rapid progress in prenatal diagnosis and medical management of CHD and to explore the impact of prenatal diagnosis on early neonatal mortality for specific (isolated) cardiac malformations. METHODS A total of 1982 cases of CHD, which were not associated with a known chromosomal anomaly, were obtained from the Paris Registry of Congenital Malformations. Main outcome measures were trends in the proportions diagnosed and terminated prior to birth, stillbirth and early (<1 day, one-week) neonatal mortality for (1) all cases; (2) all cases excluding isolated ventricular septal defects; and (3) malformation-specific trends for transposition of great arteries, hypoplastic left heart syndrome, coarctation of aorta, and tetralogy of Fallot. Analyses included cusum and binomial regression models for analysis of the trends during 1983-2000. RESULTS Prenatal diagnosis rates for CHD increased from 23.0% (95%CI: 19.0-27.4) in 1983-1988 to 47.3% (95%CI: 43.8-50.8) in 1995-2000. Termination rates increased between 1983 and 1989 (9.9%; 95%CI: 7.2-13.2) and 1989 and 1994 (14.7%; 95%CI: 12.3-17.4) but seemed to remain stable thereafter. Other than for hypoplastic left heart syndrome, pregnancy termination was exceptional for the other 3 specific malformations examined. Early neonatal mortality decreased to less than a third in the period 1995-2000 as compared with 1983-1989 (risk ratio, first week mortality: 0.31; 95%CI: 0.18-0.53). First week mortality was significantly lower for cases of transposition of great arteries diagnosed before birth (risk difference: 15.4%; 95% CI: 4.0-26.7). CONCLUSION Progress in clinical management, together with policies for increased access to prenatal diagnosis, has resulted in both a substantial increase in the prenatal diagnosis and considerable reductions in early neonatal mortality of CHD in the Parisian population.

Abstract
AIMS To assess what proportion of all cardiac abnormality can be suspected at birth when all clinical examination before discharge is undertaken by a small stable team of clinicians. METHODS A prospective audit of all the 14 572 births in a maternity unit only staffed by nurse practitioners between 1996 and 2003. RESULTS 1.2% of all babies born in the unit were found to have a structural defect (as confirmed by echocardiography) within a year of birth. The number not suspected before discharge declined over time, and only 6% were first suspected after discharge in the last four years of this eight year study. Four potentially life threatening conditions initially went unsuspected in 1996-8, but none after that. A policy of referring every term baby with a murmur at 1 day of age that was still present at 7-10 days resulted in 4.2% requiring cardiac referral; 54% of these babies still had a murmur when assessed one to two weeks later, and 33% had a structural defect. Parents said in independent, retrospectively conducted, interviews that they found it confidence building to have any possible heart defect identified early and the cause of any murmur clearly and authoritatively explained. CONCLUSIONS Effective screening requires experience and a clear, structured, referral pathway, but can work much better than most previous reports suggest. Whether staff bring a medical or nursing background to the task may well be of less importance.
