An
engineer comparing the
human adult heart and
the embryo heart might
never guess that the
former developed from
the latter. But
new results from Gharib's
Group published
in Science show that the embryonic
vertebrate heart tube
is a dynamic suction
pump. Blood
flows through it by a
dynamic suction action
(similar to the action
of the mature left ventricle)
that arises from wave
motions in the tube. Read

Building on years of research on the way that
blood flows through the heart valves, Mory
Gharib,
Liepmann Professor of Aeronautics and Bioengineering,
and his colleagues have devised a new index for cardiac
health based on a simple ultrasound test. Read

| Research by Dr.'s Jay
Hove (Gharib's Group) and
Reinhard Koster (Fraser's
Group) add to the growing
evidence that cardiovascular disease may be
rooted in processes initiated in the developing
embryo and fetus. New in vivo imaging techniques
based on confocal microscopy confirm that intracardiac
fluid forces are essential for normal heart looping
and for chamber and valve development in early
embryonic zebrafish. See cover article in Nature,
January 8, 2003.
