Hemodynamic Assessment of Infants With Congenital Heart Disease Using Ferumoxytol-Enhanced 4D Flow Cardiac Magnetic Resonance.

In complex congenital heart disease, characterization of the circulation is necessary to anticipate the clinical course. Four-dimensional cardiac magnetic resonance imaging enhanced by superparamagnetic iron oxide contrast agents (ferumoxytol) enables detailed and efficient assessment of both anatomy and physiology in neonates. We demonstrate this impact in 3 cases of neonates with congenital heart disease.
