At the London School of Ultrasound, we believe that the most clinically important fetal anomalies can be diagnosed by screening in the 1st trimester.

This year, we are delighted to present a unique opportunity for fetal medicine, obstetrics and ultrasound professionals, fetal cardiologists and geneticists to gather and explore the latest developments in screening for CHD at 10-14 weeks and Early Fetal Echocardiography (eECHO) at 6th Early Scan Conference, which will be held in London on 23-24 September 2023.

Congenital heart disease (CHD) is a major diagnostic and management challenge for fetal medicine specialists, ultrasound professionals, and cardiologists. However, significant advances have been made in our understanding of the early manifestations of CHD: the development of the newest ultrasound technology has made it possible to detect the majority of severe CHD at 10-14 weeks through a simple scanning protocol.

During this conference, we will explore all aspects of early diagnosis, verification, counselling, diagnostic work-up, and management of CHD. We will have an excellent panel of speakers who are experts in the field and who will share their knowledge and expertise with us.

The conference was planned to be in London in 2020, but it was held virtually due to the pandemic. However, there have been significant advances in first-trimester echocardiography in just three years. This year’s conference’s agenda will be revised to engage with the latest advances in this vital field.

The conference is designed to be a face-to-face event, allowing you to network with your peers and engage in thought-provoking discussions on the latest developments in this field. We believe that this conference will be an excellent opportunity for you to expand your knowledge, network with colleagues, and share your own experiences.

Don’t miss out on this opportunity to learn about the latest developments in early CHD screening and network with colleagues worldwide.

We look forward to seeing you in London in 2023!


The Conference is dedicated to fetal medicine and ultrasound specialists, fetal cardiologists, obstetricians, sonographers, and other professionals managing low and high-risk pregnancies.
