Trends of mortality rate in patients with congenital heart defects in Germany-analysis of nationwide data of the Federal Statistical Office of Germany. Clin Res Cardiol 2024; 113:750-760. [PMID: 38436738 PMCID: PMC11026207 DOI: 10.1007/s00392-023-02370-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/28/2023] [Accepted: 12/30/2023] [Indexed: 03/05/2024]
Abstract
BACKGROUND Congenital heart defects (CHD) are still associated with an increased morbidity and mortality. The aim of this study was to analyze trends of mortality rates in patients with CHD between 1998 and 2018 in Germany. METHODS Data of registered deaths with an underlying diagnosis of CHD were used to evaluate annual mortality between 1998 and 2018. Polynomial regressions were performed to assess annual changes in CHD-associated mortality rates by age groups. RESULTS During the 21-year study period, a total of 11,314 deaths were attributed to CHD with 50.9% of deaths in infants (age < 1 year) and 28.2% in neonates (age ≤ 28 days). The most frequent underlying CHDs associated with death were hypoplastic left heart syndrome (n = 1498, 13.2%), left ventricular outflow tract obstruction (n = 1009, 8.9%), atrial septal defects (n = 771, 6.8%), ventricular septal defects (n = 697, 6.2%), and tetralogy of Fallot (n = 673, 5.9%), and others (n = 6666, 58.9%). Among all patients, annual CHD-related mortality rates declined significantly between 1998 and 2010 (p < 0.0001), followed by a significant annual increase until 2018 (p < 0.0001). However, mortality rates in 2018 in all ages were significantly lower than in 1998. CONCLUSION Mortality in CHD patients decreased significantly between 1998 and 2010, but a substantial number of deaths still occurred and even significantly increased in the last 3 years of the observation period particularly in neonates and infants. This renewed slight increase in mortality rate during the last years was influenced mainly by high-risk neonates and infants. Assessment of factors influencing the mortality rate trends in association with CHD in Germany is urgently needed. Obligatory nationwide registration of death cases in relation to surgical and catheter interventions in CHD patients is necessary to provide additional valuable data on the outcome of CHD.

Reduction of infant mortality from congenital heart defects in a middle-income country: Costa Rican experience. Birth Defects Res 2022; 114:1364-1375. [PMID: 36177489 DOI: 10.1002/bdr2.2093] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/17/2022] [Revised: 08/26/2022] [Accepted: 09/07/2022] [Indexed: 11/09/2022]
Abstract
BACKGROUND We aimed to analyze recent infant and neonatal mortality from congenital heart defects (CHD) in Costa Rica, a middle-income country where CHD mortality was above expectations. METHODS A descriptive analysis of infant and neonatal mortality rates from CHD (IMR-CHD and NMR-CHD) during 2000-2019 was performed, according to province, sex, specific CHD, and sub-period, using data from the National Institute of Statistics and Censuses. We used joinpoint regression to identify any calendar-year where a significant change in trend occurred; the average annual percent change (AAPC) was determined. Using Poisson regression, marginal means and mortality ratios (MR) for IMR-CHD and NMR-CHD by sub-period (2000-2006-referent-, 2007-2013, 2014-2019) were estimated and compared using Wald's chi-square tests (α ≤ .05). RESULTS During 2000-2019, CHD accounted for 12% of overall infant mortality. IMR-CHD and NMR-CHD decreased linearly over the study period (AAPC = -3.4; p < .01). IMR-CHD decreased by 41%, from 13.6 per 10,000 in 2000-2006 (13.4% of infant mortality) to 8.1 per 10,000 in 2014-2019 (10% of infant mortality) (MR = 0.59; 95% confidence intervals [CI] = 0.52-0.68). NMR-CHD decreased by 38%, from 7.9 per 10,000 in 2000-2006 (11.1% of neonatal mortality) to 4.9 per 10,000 in 2014-2019 (7.9% of infant mortality) (MR = 0.59; 95% CI = 0.52-0.68). Male presented significantly higher NMR-CHD. The main causes of mortality (2014-2019) were total anomalous pulmonary venous connections, hypoplastic left heart syndrome, and double inlet ventricle. CONCLUSIONS IMR-CHD, NMR-CHD, and their proportional contribution to mortality by all causes and by birth defects decreased significantly, demonstrating that all improvements implemented in the last decades have yielded favorable results.

Abstract
Congenital heart disease (CHD) is the most common birth defect. The prenatal diagnosis of fetal CHD is completely dependent on ultrasound testing, but only ~40% of CHD can be detected. The purpose of this study is to find good biomarkers in amniotic fluid (AF) to detect CHD in the second trimester, so as to better manage this group of people and reduce the harm of CHD to the fetus. Metabolites analysis were performed in two separate sets. The discovery set consisted of 18 CHD fetal maternal AF samples and 35 control samples, and the validation set consisted of 53 CHD fetal maternal AF samples and 114 control samples. Untargeted metabolite profiles were analyzed by gas chromatography/time-of-flight-mass spectrometry (GC-TOF/MS). Orthogonal partial least square discrimination analysis (OPLS-DA) demonstrated that CHD and control samples had significantly different metabolic profiles. Two metabolites, uric acid and proline, were significantly elevated in CHD and verified in two data sets. Uric acid was associated with CHD [odds ratio (OR): 7.69 (95% CI: 1.18-50.13) in the discovery set and 3.24 (95% CI:1.62-6.48) in the validation set]. Additionally, uric acid showed moderate predictive power; the area under curve (AUC) was 0.890 in the discovery set and 0.741 in the validation set. The sensitivity and specificity of uric acid to detect CHD was, respectively, 94.4 and 74.3% in the discovery set and 67.9 and 71.9% in the validation set. The identification of uric acid as a biomarker for CHD has the potential to stimulate research on the pathological mechanism of CHD and the development of a diagnostic test for clinical applications.

Congenital heart diseases: genetics, non-inherited risk factors, and signaling pathways. EGYPTIAN JOURNAL OF MEDICAL HUMAN GENETICS 2020.

Abstract
Abstract
Background
Congenital heart diseases (CHDs) are the most common congenital anomalies with an estimated prevalence of 8 in 1000 live births. CHDs occur as a result of abnormal embryogenesis of the heart. Congenital heart diseases are associated with significant mortality and morbidity. The damage of the heart is irreversible due to a lack of regeneration potential, and usually, the patients may require surgical intervention. Studying the developmental biology of the heart is essential not only in understanding the mechanisms and pathogenesis of congenital heart diseases but also in providing us with insight towards developing new preventive and treatment methods.
Main body
The etiology of congenital heart diseases is still elusive. Both genetic and environmental factors have been implicated to play a role in the pathogenesis of the diseases. Recently, cardiac transcription factors, cardiac-specific genes, and signaling pathways, which are responsible for early cardiac morphogenesis have been extensively studied in both human and animal experiments but leave much to be desired. The discovery of novel genetic methods such as next generation sequencing and chromosomal microarrays have led to further study the genes, non-coding RNAs and subtle chromosomal changes, elucidating their implications to the etiology of congenital heart diseases. Studies have also implicated non-hereditary risk factors such as rubella infection, teratogens, maternal age, diabetes mellitus, and abnormal hemodynamics in causing CHDs.
These etiological factors raise questions on multifactorial etiology of CHDs. It is therefore important to endeavor in research based on finding the causes of CHDs. Finding causative factors will enable us to plan intervention strategies and mitigate the consequences associated with CHDs. This review, therefore, puts forward the genetic and non-genetic causes of congenital heart diseases. Besides, it discusses crucial signaling pathways which are involved in early cardiac morphogenesis. Consequently, we aim to consolidate our knowledge on multifactorial causes of CHDs so as to pave a way for further research regarding CHDs.
Conclusion
The multifactorial etiology of congenital heart diseases gives us a challenge to explicitly establishing specific causative factors and therefore plan intervention strategies. More well-designed studies and the use of novel genetic technologies could be the way through the discovery of etiological factors implicated in the pathogenesis of congenital heart diseases.
