AI Article Synopsis
- The study aimed to analyze genetic testing patterns in infants with congenital heart disease (CHD) compared to those without CHD in a NICU setting.
- A total of 1,075 out of 7,112 infants underwent genetic evaluation, with a notable focus on 329 infants with CHD.
- Results showed similar diagnosis rates post-testing for both groups, but atrioventricular septal defects were highly predictive of a genetic diagnosis, suggesting the importance of genetic testing in these cases.
Article Abstract
Objective: To evaluate patterns of genetic testing among infants with CHD at a tertiary care center.
Study Design: We conducted a retrospective observational cohort study of infants in the NICU with suspicion of a genetic disorder. 1075 of 7112 infants admitted to BCH had genetic evaluation including 329 with CHD and 746 without CHD. 284 of 525 infants with CHD admitted to CMHH had genetic evaluation. Patterns of testing and diagnoses were compared.
Results: The rate of diagnosis after testing was similar for infants with or without CHD (38% [121/318] vs. 36% [246/676], p = 0.14). In a multiple logistic regression, atrioventricular septal defects were most high associated with genetic diagnosis (odds ratio 29.99, 95% confidence interval 2.69-334.12, p < 0.001).
Conclusions: Infants with suspicion of a genetic disorder with CHD had similar rates of molecular diagnosis as those without CHD. These results support a role for genetic testing among NICU infants with CHD.

Background Children with Down syndrome (DS) often have hypoplastic kidneys and urinary tract malformations that increase their renal dysfunction risk. They also have a higher congenital heart disease (CHD) rate, requiring cardiac surgery during infancy. Renal dysfunction in such patients may be associated with the development of cardiac surgery-associated acute kidney injury (CS-AKI), but this remains unclear.

Congenital heart defects (CHDs) are caused by a complex interaction between numerous genetic and environmental risk factors, some of which may differ between different populations. A case-control study was conducted among 1232 newborns, including 308 patients with isolated CHDs (cases) and 924 infants without birth defects (controls), born all during the period 2009-2023 at the Hospital Civil de Guadalajara "Dr. Juan I.

Introduction: This study investigates risk factors and surgical outcomes in pediatric patients with congenital heart defects (CHD) who develop ischemic colitis (IC). Previous research indicates a higher IC risk in very low birth weight neonates with CHD.
Methods: A retrospective analysis compared an IC-CHD group to a CHD-only group.

Background: Respiratory Syncytial Virus (RSV) is a common cause of hospitalisation in infants worldwide, causing significant morbidity and mortality. Recently, the antiviral treatment, Ziresovir, has shown promising results in a Phase III trial conducted on infants hospitalised with RSV. Based on these topline results, this study aims to investigate the cost-effectiveness of Ziresovir in the United Kingdom (UK).

Background: Individuals have a higher risk of cardiovascular disease later in life if they give birth to a child with congenital heart disease (CHD). The mechanism of this association has not been well documented.
Objectives: The authors aimed to describe the prevalence of cardiovascular disease and risk factors in women and birthing individuals 18 to 23 years after delivery of a child with CHD compared to normative data.
