Vortex formation has received much atten¬
tion over the past few years. Vortices occur in
nature wherever propulsive flow exists; from
erupting volcanoes to the ones generated by
squid and jellyfish to propel them. There has
been particular interest in the wide variety
of vortices that develop in the cardiovascular
system, particularly in the cardiac chambers
and in large arteries. These vortices play fun¬
damental roles in the normal physiology and
provide proper balance between blood motion
and stresses on the surrounding tissues.
In contrast, formation of unnatural vortices
may alter the momentum transfer in the
blood flow and increase energy dissipation.
Vortex Formation in the Cardiovascular
System reviews the current knowledge of
vortex formation, from the basic physics to
cardiac physiology. There is a particular focus
on the formation of vortices at different loca¬
tions inside the heart, the effect of cardiac
devices and surgery on vortex formation,
fluid dynamics of the artificial heart valves
and ventricular assist devices. The authors
have translated physical, mathematical and
engineering concepts related to vortex forma¬
tion into a clinical perspective with the objec¬
tive to advance cardiovascular patient care.
This book therefore represents a compre¬
hensive and valuable resource for those
involved in the field of
cardiolog)
and cardio¬
vascular physiology, cardiovascular surgeons,
interventional cardiologists, medical bioengi-
neers and researchers in fluid mechanics.
