Population-Based Estimates of the Prevalence of Children With Congenital Heart Disease and Associated Comorbidities in the United States. Circ Cardiovasc Qual Outcomes 2024; 17:e010657. [PMID: 39185543 DOI: 10.1161/circoutcomes.123.010657] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/24/2023] [Accepted: 06/19/2024] [Indexed: 08/27/2024]
Abstract
BACKGROUND Congenital heart defects (CHD) are the most common birth defects and previous estimates report the disease affects 1% of births annually in the United States. To date, CHD prevalence estimates are inconsistent due to varied definitions, data reliant on birth registries, and are geographically limited. These data sources may not be representative of the total prevalence of the CHD population. It is therefore important to derive high-quality, population-based estimates of the prevalence of CHD to help care for this vulnerable population. METHODS We performed a descriptive, retrospective 8-year analysis using all-payer claims data from Colorado from 2012 to 2019. Children with CHD were identified by applying International Classification of Diseases-Ninth Revision (ICD-9) and International Classification of Diseases-Tenth Revision (ICD-10) diagnosis codes from the American Heart Association-American College of Cardiology harmonized cardiac codes. We included children with CHD <18 years of age who resided in Colorado, had a documented zip code, and had at least 1 health care claim. CHD type was categorized as simple, moderate, and severe disease. Association with comorbid conditions and genetic diagnoses were analyzed using χ2 test. We used direct standardization to calculate adjusted prevalence rates, controlling for age, sex, primary insurance provider, and urban-rural residence. RESULTS We identified 1 566 328 children receiving care in Colorado from 2012 to 2019. Of those, 30 512 children had at least 1 CHD diagnosis, comprising 1.95% (95% CI, 1.93-1.97) of the pediatric population. Over half of the children with CHD also had at least 1 complex chronic condition. After direct standardization, the adjusted prevalence rates show a small increase in simple severity diagnoses across the study period (adjusted rate of 11.5 [2012]-14.4 [2019]; P<0.001). CONCLUSIONS The current study is the first population-level analysis of pediatric CHD in the United States. Using administrative claims data, our study found a higher CHD prevalence and comorbidity burden compared with previous estimates.

Diagnostic value of four-dimensional ultrasonography with STIC combined with two-dimensional ultrasonography for fetal cardiac malformation and chromosomal abnormalities in early pregnancy. Exp Ther Med 2019; 19:1161-1166.

Abstract
Diagnostic value of four-dimensional ultrasonography with spatio-temporal image correlation (STIC) technique combined with two-dimensional ultrasonography for fetal cardiac malformation and chromosomal abnormalities in early pregnancy was investigated. Medical data of 178 pregnant women enrolled in Tianjin Central Hospital of Gynecology and Obstetrics for screening of fetal cardiac malformations and chromosomal abnormalities from January 2014 to March 2016 were collected. According to the results of the pregnant women's biopsy and the results of labor induction and delivery, 95 fetuses were diagnosed with chromosomal abnormalities and cardiac malformations, 40 fetuses with cardiac malformations and no chromosomal abnormalities, and 43 fetuses with neither cardiac malformations nor chromosomal abnormalities. Fetal cardiac malformations and chromosomal abnormalities were diagnosed by three methods: single two-dimensional ultrasonography, single four-dimensional ultrasonography with STIC, and a combination of two-dimensional ultrasonography and four-dimensional ultrasonography with STIC. The two-dimensional ultrasonography diagnosed 97 cases of fetal cardiac malformation and 61 cases of chromosomal abnormalities, four-dimensional ultrasonography with STIC diagnosed 122 cases of fetal cardiac malformation and 81 cases of chromosomal abnormalities. The combination of two-dimensional ultrasonography and four-dimensional ultrasonography diagnosed 130 cases of fetal cardiac malformation and 90 cases of chromosomal abnormalities. The sensitivities of four-dimensional ultrasonography with STIC and the combination of two-dimensional ultrasonography and four-dimensional ultrasonography were significantly higher than that of single examination by two-dimensional ultrasonography (P<0.05), while the diagnostic sensitivities by four-dimensional ultrasonography with STIC and the combined diagnosis were not statistically significant (P>0.05). The diagnostic accordance rates of the single four-dimensional ultrasonography and the combined diagnosis for fetal cardiac malformations and chromosomal abnormalities were not much different (P>0.05), but both were greatly higher than that of single two-dimensional ultrasonography diagnosis (P<0.05). Thus, a combination of four-dimensional ultrasonography with STIC and two-dimensional ultrasonography is recommended for screening fetal defects.

Abstract
We evaluated 2,083 cases within the Wisconsin Stillbirth Service Program (WiSSP) that had autopsy reports or ultrasound data relevant to the heart. Of these, 167/1,782 (9.4%) stillbirths after 20 weeks and 11/301 (3.7%) miscarriages <20 weeks had congenital heart disease (CHD). Cases were classified by type of heart defect and whether it related to cause of death. Among cardiac anomalies that contributed significantly to fetal death, 125/151 (83%) were associated with underlying conditions or syndromes, nearly half of which were chromosomal. The most common forms of CHD in stillborns were severe cyanotic lesions (3%), then ventricular (2.6%) and atrial (1.9%) septal defects. Compared to livebirths, this represents a shift toward more severe cardiac lesions, although all comparable categories, including non-lethal conditions such as atrial septal defect, are more common in stillbirths. Clinical cardiomyopathy was identified as cause of death in 1.2% of stillborns. Cardiomegaly, occurring in 26.7% of all cases and 76.7% of infants born to diabetic mothers, may represent undiagnosed cardiomyopathy and/or may decrease fetal tolerance of hypoxia. In contrast, 78.5% of Turner syndrome infants, all <32 weeks, had small hearts. More attention to cardiac findings can lead to increased understanding of stillbirth causes. Based on our findings, we recommend chromosome studies on all stillbirths and close attention to the heart during second trimester ultrasounds, with chromosome studies offered if CHD is found. Consideration of heart size can result in prenatal identification of infants at risk for stillbirth, particularly large hearts in fetuses of diabetic mothers in the third trimester, which may identify fetal cardiomyopathy before it becomes life-threatening.

Abstract
We report on a child with dextrocardia, atrial septal defect (ASD), severe developmental delay, hypotonia, 13 pairs of ribs, left preauricular choristoma, hirsutism, and craniofacial abnormalities. Prenatal cytogenetic evaluation showed karyotype 46,XY,?dup(8p)ish del(8)pter. Postnatal array CGH demonstrated a 6.8 Mb terminal deletion at 8p23.3-p23, an interstitial 31.1 Mb duplication within 8p23.1-p11, and a terminal duplication of 0.24 Mb at 22q13.33, refining the karyotype to 46,XY,der(8)dup(8)(p23.1p11.1)t(8;22)(p23.1;q13.1).ish der(8)dup(8)(p23.1p11.1)t(8;22)(p23.1;q13.1) (D8S504-,MS607 + ,ARSA + ,D8Z1 + , RP115713 + +). Previous reports of distal 8p deletion, 8p duplication, and distal 22q duplication have shown similar manifestations, including congenital heart disease, intellectual impairment, and multiple minor anomalies. We correlate the patient's clinical findings with these particular areas of copy number. This case study supports the use of aCGH to identify subtle chromosomal rearrangement in infants with cardiac malformation as their most significant or only apparent birth defect. Additionally, it illustrates why aCGH is essential in the description of chromosome rearrangements, even those seemingly visible via routine karyotype. This method shows that there is often greater complexity submicroscopically, essential to an adequate understanding of a patient's genotype and phenotype.

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
We report a case wherein a dysmorphic four-month-old infant (weighing 4.5 kgs) with an 8 mm atrial septal defect (ASD), a 1.5 mm patent ductus arteriosus (PDA), a 2 mm mid-muscular ventricular septal defect (VSD) associated with chronic lung disease, and severe pulmonary hypertension, was successfully managed using a hybrid approach, without the use of cardiopulmonary bypass (CPB). Through a median sternotomy, the PDA was ligated and the ASD was closed with a 9 mm Amplatzer septal occluder implanted through peratrial access. The VSD was left untouched. Serial echocardiograms showed complete closure of the ASD and PDA, with progressive normalization of the pulmonary artery (PA) pressures within three months. The child rapidly gained weight and was weaned from sildenafil and oxygen administration. After 12 months, the VSD closed spontaneously and the child remained well, with normal PA pressures. A hybrid approach without the use of CPB should be considered in the management of infants with congenital heart disease, associated with chronic lung disease and pulmonary hypertension.

Abstract
The aim of our study was to investigate the incidence of congenital defects in children born in Croatia during a period of 5 years, its association with extracardiac malformations, its treatment, and outcome. Medical information about the patients was obtained from 14 paediatric cardiology centres that cover the whole country. Diagnosis was made by clinical findings, electrocardiography, chest X-ray, echocardiography, catheterisation, or autopsy. Between October 1, 2002 and October 1, 2007, there were 205,051 live births in Croatia, 1,480 of which were patients diagnosed with congenital heart disease, accounting for 0.72% of the live-born children. The distribution was made up of 34.6% children with ventricular septal defect, 15.9% with atrial septal defect, 9.8% with patency of arterial duct, 4.9% with pulmonary valvar stenosis, 3.3% with tetralogy of Fallot, 3.3% with transposed great arteries, 3.3% with aortic stenosis, 3.2% with aortic coarctation, 4.3% with atrioventricular septal defect and common atrioventricular orifice, 2.3% with hypoplastic left heart syndrome, and 8.3% other with severe defects. The average age in the time of diagnoses is 70.41 days (SD, 188.13), with low average time of diagnoses of severe heart defects, 9.6 days (SD, 32.52). Among patients, 14.5% had chromosomal defects, syndromes, and/or other congenital major anomalies. During the study, 57 patients died because of cardiac anomalies or other related problems, 24 who died were operated. The rates of specific cardiac defects and association with extracardiac malformations are generally comparable with those reported in similar studies. In spite of all problems, mortality rate of 3.85% is low but could be improved.

Abstract
PURPOSE We report ophthalmic manifestations in four Jacobsen syndrome cases, review the literature, and suggest phenotype-genotype correlations. METHODS Chart review of Ocular Genetics Program patients at The Hospital for Sick Children, Toronto, Canada. RESULTS Four del11qter cases are presented. Hypertelorism/telecanthus, abnormally slanted palpebral fissures, abnormal retinal findings, nasolacrimal duct obstruction, anomalous extraocular muscles, amblyopia, and microcornea were found. CONCLUSIONS We report typical findings and novel ocular presentations. Visual prognosis is generally good. Retinal dysplasia and coloboma seem associated with del11q23. ABCG4, NCAM, and Mfrp are candidate genes in this region that theoretically may be disrupted.

Abstract
A new case of 11q interstitial duplication is reported in a patient with mild dysmorphic features but normal development. Chromosome analysis revealed a de novo 11q dup(11)(q14.1q21) on G banding and FISH studies. Additional molecular genetic studies revealed a similar but more distal duplication at the level of 11q21q23.1. Previous cases of isolated 11q duplication that overlapped with this case were associated with a wide variety of clinical findings and variable developmental disability. These cases all included additional material not duplicated in this patient. The current case represents the first de novo case of 11q duplication with normal development suggesting that the segment between 11q14.1 and 11q21 contains few genes that are dose sensitive. Review of other cases that have used conventional cytogenetic resolution studies suggests that the band 11q13.5 may contain genes contributing to the developmental disabilities in the cases previously reported with proximal 11q duplication. Differences between conventional cytogenetic techniques and newer molecular genetic studies are expected. These newer techniques will help refine prognosis and counseling for families in the future.

Abstract
Tetrasomy 8p is a rare chromosomal disorder that has only been detected in a mosaic form. At the present time, 11 cases have been reported; their phenotype included agenesis of the corpus callosum, enlarged ventricles, minor facial dysmorphism, rib and vertebral anomalies, and mild to moderate developmental delay. To the best of our knowledge, tetrasomy 8p has never been prenatally diagnosed. This 43-year-old woman was referred for amniocentesis at 20 weeks' gestation because of advanced maternal age. Amniotic fluid cells were cultured according to standard techniques by the in situ method. A supernumerary chromosomal marker was detected in a single clone of cultured amniotic cells and interpreted by RHG banding as an isochromosome of the short arm of chromosome 8 (i(8p)). The ultrasound investigation at 27 weeks gestation revealed enlarged ventricles and agenesis of the corpus callosum, which were confirmed at fetal autopsy after medical termination of the pregnancy. Chromosomal analyses, including RHG banding and FISH, of several tissues showed different levels of i(8p) mosaicism. Whereas no i(8p) was detected on cytotrophoblast nor additional amniotic fluid cells, 97% and 30% of cells from long-term cultures of placenta and lymphocytes, respectively, had the i(8p). Using DNA markers, the isochromosome 8p was interpreted as the result of a prezygotic event during maternal meiosis. Our findings suggest that the i(8p) is the subject of tissue selection. Tetrasomy 8p might be underdiagnosed during pregnancy; therefore, karyotyping on a fetal blood sample following detection of agenesis of the corpus callosum when no chromosomal abnormality has been found on the amniotic fluid cell cultures should be discussed with the parents.

Abstract
We describe a 5-month-old boy with complex congenital heart defects (dTGA, DORV, VSD, ASD, and PDA), minor facial and ear anomalies, deep palmar creases, multiple vertebral anomalies, agenesis of the corpus callosum, and mosaic tetrasomy 8p (47,XY,+i(8)(p10)[88%]/46,XY[12%] in blood with normal chromosomes in cultured skin fibroblasts. This infant represents the eleventh reported case of mosaic tetrasomy 8p since its first description by Kristofferson et al. [1988: Clin Genet 34:201-203]. The pattern of heart malformations and discordance of blood and fibroblast karyotypes make our case unique. Our report and review suggest that an important distinction between mosaic tetrasomy 8p and other chromosome 8 aneuploidies involves the increased incidence and complexity of congenital heart malformations.

Abstract
Refinements in cytogenetic techniques have promoted progress in understanding the role that chromosome abnormalities play in the cause of congenital heart disease. To determine if mutations at specific loci cause congenital heart disease, irrespective of the presence of other defects, and to estimate the prevalence of chromosome abnormalities in selected conotruncal cardiac defects, we reviewed retrospectively cytogenetic and clinical databases at St. Louis Children's Hospital. Patients with known 7q11.23 deletion (Williams syndrome), Ullrich-Turner syndrome (UTS), and most autosomal trisomies were excluded from this analysis. Two groups of patients were studied. Over a 6.5-year period, 57 patients with chromosomal abnormalities and congenital heart disease were identified. Of these, 37 had 22q11 deletions; 5 had abnormalities of 8p; and 15 had several other chromosome abnormalities. The prevalence of chromosome abnormalities in selected conotruncal or aortic arch defects was estimated by analysis of a subgroup of patients from a recent 22-month period. Chromosome abnormalities were present in 12% of patients with tetralogy of Fallot, 26% in tetralogy of Fallot/pulmonary atresia, 44% in interrupted aortic arch, 12% in truncus arteriosus, 5% in double outlet right ventricle, and 60% in absent pulmonary valve. We conclude that chromosome analysis should be considered in patients with certain cardiac defects. Specifically, fluorescent in situ hybridization (FISH) analysis of 22q11 is indicated in patients with conotruncal defects or interrupted aortic arch. High resolution analysis should include careful evaluation of the 8p region in patients with either conotruncal or endocardial cushion defects.

Abstract
We report on a patient with duplication of 7p15-->pter and review the literature. Patients with partial duplication of the distal 7p, including only the distal segment 7p15-->pter, have a syndrome comparable to that of patients with a larger or complete duplication of 7p. This suggests that the critical region for the dup(7p) phenotype is restricted to 7p15-->pter. The complete clinical phenotype of dup(7)(p15-->pter) includes mental retardation, skull anomalies, large anterior fontanel, cardiovascular defects, joint dislocation and contraction, and gastrointestinal and genital defects. Recognition of the clinical spectrum in patients with a smaller duplication of 7p, and the assignment of this critical region, should prove valuable for accurate counseling, prediction of outcome, and further gene mapping.

Abstract
In the Baltimore-Washington Infant Study, a regional case-control study of 4,390 liveborn infants with cardiovascular malformations (CVM), 642 patients (14.2%) had outflow tract abnormalities, with extracardiac defects in 157 (approximately 25%) of them. Associated defects were found in 1/3 of patients with normal great arteries, but only in 1/10 of patients with transposition of great arteries (TGA). The extracardiac defects were especially rare in the groups "TGA with intact ventricular septum" and "TGA with ventricular septal defect". Patients with multiple associated defects outnumbered patients with isolated associated defects in the ratio 2.5:1. The associated defects were heterogeneous: 46 patients had chromosome abnormalities, 16 had different Mendelian syndromes, and 36 had associations (DiGeorge sequence and VACTERL association were the most frequent). A new syndrome of multiple congenital abnormalities including tetralogy of Fallot, and rare cases of chromosomal and Mendelian syndromes (distal trisomy 1q, tetrasomy 8p, Holzgreve syndrome) are described briefly. Sufficient variability of a spectrum of conotruncal defects in the patients with the same chromosomal or Mendelian syndromes suggests that at least in some cases different conotruncal defects are stages of the same morphologic spectrum. The analysis of conotruncal defects in sibs of patients with Mendelian syndromes may provide new data about the links between different definitive forms of CVM.

Abstract
A male infant presenting with multiple anomalies including a midline cleft palate, anasarca, hepatomegaly, pulmonary edema, agenesis of the corpus collosum, and complex congential cardiac anomalies was found to have mosaicism for an additional chromosome that appeared (following GTG-banding and FISH) to be a monocentric isochromosome of the short arm of chromosome 8 (46,XY/47,XY, +i(8p)). Nine other cases of mosaicism for an additional i(8p) were reviewed. Considerable phenotypic variation was noted. Consistent features were identified including agenesis of the corpus callosum, cardiac malformations, and minor facial dysmorphology. The phenotype of these patients partially overlaps those of trisomy 8 and trisomy 8p. By studying additional individuals with this condition, mosaic tetrasomy 8p may emerge as a recognizable clinical phenotype.

Abstract
We report the case of a 5-year-old girl with severe developmental disabilities, skeletal anomalies, hypotonia, rectal atresia, malrotation of the intestine, horseshoe kidney, vesicoureteric reflux, and minor facial anomalies. Conventional cytogenetic techniques suggested that she had a mosaic 46,XX/47,XX,+i(8p) constitution, and the identity of the isochromosome was confirmed by in situ hybridization and chromosome painting. Polymorphic DNA markers are consistent with the i(8p) having arisen as the result of a segregation error and centromere misdivision at the second maternal meiotic division. The i(8p) was seen in 17/25 (68%) lymphocytes at the age of one month but had declined to 31/100 (31%) cells by the age of 5 years. At this time the i(8p) was seen in 30/68 (44%) cultured skin fibroblasts. The proposita had an approximately twofold increase in red cell glutathione reductase activity but a normal level of tissue-plasminogen activator. These enzyme results are consistent with the known localisation of the glutathione reductase gene on the short arm of chromosome 8 but suggest that the tissue-plasminogen activator gene may map outside this region.
