ISUOG, its members and partners, have the passion and connections to drive global discussions that implement change and improve detection rates.
As part of the Every Little Heart Matters campaign we are curating a library of free educational resources, supported by our partnering societies and industry partners, to enhance the knowledge of healthcare professionals in the field.
It’s early days for the campaign and ISUOG already has a wealth of resources that we have made freely available. A virtual issue on congenital heart disease has been curated, in support of the campaign, featuring the latest research and expert guidance on prenatal screening, management, novel diagnostic methods and more. You can read it here.

ISUOG Practice Guidelines
We have a great selection of ISUOG Practice Guidelines related to the heart.
Want to learn more? Check out the Guidelines below.
Newly updated ISUOG Practice Guidelines: performance of fetal cardiac screening
Read the newly updated ISUOG Practice Guidelines on the performance of fetal cardiac screening.
Sonographic screening examination of the fetal heart
These Guidelines can be used to maximize the detection of heart anomalies during a second-trimester examination as part of routine prenatal care.
Performance of the routine mid-trimester fetal ultrasound scan
The mid-trimester ultrasound scan is performed mainly for anatomical evaluation of the fetus. In experts’ hands, most clinically important structural anomalies can be detected.
ISUOG Practice Guidelines: performance of third-trimester obstetric ultrasound scan
This document outlines recommended guidelines for conducting third-trimester ultrasound examination, encompassing determination of placental location and fetal presentation, measurement of fetal biometry, identification of fetal anomalies, evaluation of amniotic fluid volume and documentation of fetal and uterine artery Doppler findings.
Use of Doppler velocimetry in obstetrics
This is a Practice Guideline on how to perform Doppler ultrasonography of the fetoplacental circulation. The aim is to describe pulsed Doppler ultrasound and its different modalities: spectral Doppler, color flow mapping and power Doppler, which are commonly used to study the maternal–fetal circulation.
Diagnosis and management of small-for-gestational-age fetus and fetal growth restriction
This Guideline provides definitions of FGR, previously referred to as intrauterine growth restriction, and SGA, and describes the best possible management options based on current data and knowledge
Fetal heart bites
Fetal heart bites is an educational miniseries produced by the ISUOG Next Generation Committee as part of the Every Little Heart Matters global initiative.
Watch the videos and share with anyone in your network who you feel could benefit from them. They demonstrate how to use the ISUOG guidelines in your daily practice.
Podcasts
ISUOG brings together experts in gynecology and obstetrics for conversations on the most significant topics in women's health. Sharing their insight, expertise and knowledge of ultrasound in OBGYN, they explore the challenges, limitations and innovative solutions. All views expressed in this podcast are of the speakers themselves and are not those of ISUOG and are not intended to be taken as advice.
In dialogue with UOG Editors: congenital heart disease
With an introduction from the Chair of the Every Little Heart Matters Oversight Group, Prof. Katia Bilardo, the editors of the recent Virtual Issue on Congenital Heart Disease, Prof. Anita Moon-Grady and Dr Taisto Sarkola are joined in an academic discussion on CHD.
They consider regional detection rates, key articles from the Virtual Issue on Congenital Heart Disease, AI, fetal MRI, ethical decisions in severe cases, ultrasound's role in low-resource settings and future directions of research.
Fetal cardiologist and parent perspectives: #EveryLittleHeartMatters
ISUOG Trustee, Prof. Fatima Crispi, joins with one of her former patients Ares Alma to discuss the full story of a mother faced with a life-changing diagnosis for her unborn child. Together, they provide both the patient and professional perspectives and remind listeners of the importance of early detection.
