Magnetic resonance imaging of blood velocity distribution around St. Jude medical aortic valves in patients.


BACKGROUND AND AIMS OF THE STUDY Complications after replacement of diseased heart valves with mechanical prostheses may be related to fluid dynamic disturbances. Magnetic resonance velocity mapping may allow quantitative, non-invasive, serial assessment of the blood velocity distribution around prosthetic heart valves in patients.
