New fetal cardiac imaging techniques

Rapid advances in graphics computing and micro‐engineering have offered new techniques for prenatal cardiac imaging. Some of them can be non‐invasively applied to both clinical and laboratory settings, including dynamic three‐dimensional echocardiography, myocardial Doppler imaging, harmonic ultrasound imaging, and B‐flow sonography. With clinical constraints, a few others have been mainly used in laboratories, such as endoscopic ultrasound, magnetic resonance imaging and biomicroscopy. Appropriate use and co‐use of these new tools will not only provide unique information for better clinical assessment of fetal cardiac disease but also offer new ways to improved understanding of cardiovascular development and pathogenesis.
