Novel system enables in vivo analysis of bileaflet prosthesis leakage jet turbulence
Published in Blood Weekly, November 24th, 2005
"Previous studies of leakage jet turbulence have been carried out in vitro, using a Newtonian fluid to simulate blood and large, rigid approximations to the chambers of the heart," surgeons in Denmark explained.
In their study, B.R. Travis and coauthors at Aarhus University Hospital sought "to apply an in vivo method of quantifying leakage jet turbulence to a variety of bileaflet mechanical heart valves, and thereafter to determine the effects of exercise and valve design on turbulent shear stresses within leakage flow."
