In this ISUOG 2025 session, Prof. Liona Chiu Yee Poon examines maternal cardiac hemodynamics in pregnancy, focusing on how cardiovascular adaptation can be evaluated through ultrasound-based assessment. The presentation frames maternal cardiac monitoring as an important component of understanding physiological and pathological changes during pregnancy.
The session begins by outlining normal maternal cardiovascular adaptations, including changes in cardiac output and vascular resistance. These physiological changes are discussed to provide context for why monitoring maternal cardiac hemodynamics is clinically relevant across gestation, particularly in pregnancies requiring closer surveillance.
Ultrasound is presented as a practical, non-invasive modality for assessing maternal cardiac function. The webinar reviews how ultrasound-derived measurements can be used to observe hemodynamic trends over time, supporting longitudinal assessment rather than single time-point evaluation. Emphasis is placed on repeatability and standardized measurement to ensure consistent interpretation.
The presentation then explores the role of AI-supported tools in maternal cardiac ultrasound. Rather than focusing on diagnostic outcomes, the session discusses how AI may assist with workflow-related aspects such as image acquisition support and measurement consistency. These tools are positioned as complementary aids that work alongside clinician expertise.
The session also addresses practical considerations for integrating maternal cardiac hemodynamic assessment into obstetric practice. Examiner experience, standardized protocols, and interpretation within the broader clinical context are highlighted as key factors influencing effective use of ultrasound in maternal cardiovascular monitoring.
