In a groundbreaking study published on January 13, 2024, in ‘Gynecologie, Obstetrique, Fertilite & Senologie’ (DOI: 10.1016/j.gofs.2024.01.001), leading obstetrician and gynecologist Dr. Edwin Quarello calls attention to a significant advancement in prenatal care—the possibility of screening low-risk populations for congenital heart disease (CHD) during the first trimester of pregnancy.
Early Detection: A Hope for the Future
Dr. Quarello, affiliated with Centre Image2 and the Department of Gynecology, Obstetrics, and Assisted Reproductive Technology at Saint Joseph Hospital in Marseille, France, asserts that this development could present a monumental shift in the management of CHD, one of the most common congenital anomalies detected in neonates. The early identification of CHD in fetuses could facilitate timely interventions and potentially improve health outcomes for affected children.
Up until now, CHD screening has predominantly occurred in the second trimester of pregnancy. However, with advancements in ultrasound technology and increasing expertise in fetal cardiology, there is a growing capability to detect heart defects much earlier.
Advancement in Ultrasound Technology
“Are we finally ready to screen low-risk populations for congenital heart disease in the 1st trimester of pregnancy?” Dr. Quarello poses this question within the context of recent research showing promising results in first trimester CHD screening using high-resolution ultrasound equipment and novel biomarkers. These screenings are particularly beneficial for low-risk populations who may not have been previously considered for early, specialized scanning.

Implications for Expectant Families
The possibility of including 1st trimester CHD screening in routine prenatal care for all pregnant individuals could afford many families with the knowledge and time necessary to prepare for the potential complexities of raising a child with CHD. It would also present the opportunity for prospective parents to consider a wider range of options regarding their pregnancy.
Challenges and Considerations
Introducing widespread first trimester CHD screening entails numerous considerations. From ensuring that medical personnel are adequately trained in early cardiac ultrasound to addressing the cost-effectiveness of screening, there is a wide array of logistical issues to resolve before such a program can be implemented.
Moreover, there are ethical implications when it comes to the potential for false-positive results and the anxiety that such results may cause for expectant parents. As such, ongoing research is necessary to refine screening strategies and thresholds to minimize these concerns.
International Responses
Internationally, there has been a cautiously optimistic response from the medical community. Many practitioners and health organizations recognize the potential benefits of early CHD detection, yet also voice the need for standardized protocols to ensure safe and effective screening practices.
Future Research
Dr. Quarello’s editorial signifies the beginning of a broader conversation and a spate of research poised to examine the practicalities of early CHD screening. Additional studies will likely focus on the validation of screening protocols and the assessment of the psychological impact on parents. As evidence accumulates, medical guidelines can be updated to reflect best practices for early CHD screening.
Perspectives from Professional Societies
Professional organizations, including the American College of Obstetricians and Gynecologists (ACOG) and the Society for Maternal-Fetal Medicine (SMFM), may soon deliberate on whether to incorporate first trimester CHD screening into their clinical practice guidelines.
Conclusion
Dr. Quarello’s editorial marks a pivotal moment for maternal-fetal medicine, as the paradigm possibly shifts towards more proactive and preventative care strategies. It also emphasizes the critical role of ongoing research and dialogue within the global medical community to ensure that such advancements are accessible, equitable, and uphold the highest standards of patient care.

With such an editorial in ‘Gynecologie, Obstetrique, Fertilite & Senologie’, the conversation about early screening of CHD during pregnancy is expected to grow. Dr. Quarello’s work suggests that, with the maturation of technology and techniques at hand, a seismic shift in prenatal diagnosis and care might just be on the horizon.
