Do you routinely use color kinesis for any
of the following?
1. Evaluation of regional left ventricular wall
motion during dobutamine stress echo
(J Am Coll Cardiol. 1999 Aug;34(2):409-19)
2. Regional right ventricular function
(Am J Respir Crit Care Med. 1999 Jun;159(6):1949-59)
3. Regional left ventricular wall motion in the
operating room by TEE
(J Thorac Cardiovasc Surg. 1999 May;117(5):912-7)
4. Global and regional left ventricular diastolic function
(Circulation. 1998 Mar 24;97(11):1053-61)

- Is anyone aware of data/studies validating the use of the PI jet at
end-diastole to estimate PA end-diastolic pressure (and therefore pulmonary
capillary wedge pressure or LV end-diastolic pressure, since they tend to be
very close in most subjects).
The velocity of the PI jet at the end of diastole can be converted to
pressure, and the PA end-diastolic pressure must equal this pressure plus
the RV end-diastolic pressure, which can be estimated by the RA pressure.
PA EDP could be expressed as
1) PAEDP is equal or greater than the predicted pressure difference at
end-diastole based on the PI jet
or 2) PAEDP is approximately equal to PI jet + RA pressure.
Thanks for your comments in advance.

- I feel that this follows on from my query concerning AQ at the beginning of
May. If acoustic quantification techniques are not useful as was suggested
by Dr Faber, can colour kinesis have any real clinical relevance?
