Advances in Fetal Cardiac Imaging and Intervention.

The field of fetal cardiology has evolved significantly in recent years. This review focuses on specific advances in fetal cardiac imaging and intervention that are increasingly used in clinical practice. On the imaging frontier, updated screening guidelines and artificial intelligence hold promise for improving prenatal detection of congenital heart disease. Advances in ultrasound technology and magnetic resonance imaging techniques have enabled greater diagnostic and prognostic accuracy of fetal heart disease from the first to third trimesters, and maternal hyperoxygenation can offer additional physiological insights. Fetal cardiac therapy has also seen great progress, with advances in transplacental pharmacologic treatments, infusions of enzyme replacement therapy, and fetal surgery for select rare and severe conditions.
