Dear Dr. Williams,
Thank you so much for this information. I will definitely be
passing it onto my vet. He was hoping that you or someone on
the list may have an idea of where he could obtain the
information as he has been unsuccessful as of now.
My ferret Mikey, and I are very grateful. Hopefully this may
assist in finding out what is wrong with him.
Yours sincerely,
Stephanie Noonan

Dear Stephanie:
Echocardiography is an area that is far outside the realm of
my
specialty. However, the following reference may be of help
to your
vet:

M-mode and Doppler echocardiographic findings in normal
ferrets
sedated with ketamine hydrochloride and midazolam.
Stepien RL, Benson KG, Wenholz LJ.
Department of Medical Sciences, University of Wisconsin
School of
Veterinary Medicine, Madison 53706, USA.
M-mode and Doppler echocardiographic values were obtained
from 30
normal adult ferrets (14 neutered females, 13 neutered
males, 3
intact males) sedated with an intramuscular combination of
ketamine
hydrochloride and midazolam. Routine M-mode measurements of
the left
and right ventricle, left atrium (LA) and aorta (AO) and
Doppler
measurements of aortic and pulmonic outflow, and mitral
inflow were
recorded. The following values were calculated: LA:AO
diameter, ratio
of peak E: peak A wave velocity (E:A ratio) for mitral
inflow, and
stroke volume (SV), cardiac output (CO) and cardiac index
(CI) for
both pulmonary and aortic outflow tracts. Maximal aortic
velocities
(AOmax) and velocity-time integral values (AO VTI) were
significantly
less than corresponding pulmonary outflow tract values
(PAmax, PA
VTI) but there was no difference in calculated values for
SV, CO or
CI. Calculated CO values were in the range expected based on
the size
of the species. Difficulties in aligning the aortic outflow
tract for
Doppler imaging may make pulmonary outflow Doppler values
more
consistent for use in estimating volume flow in ferrets.
I would submit that the calculated values in this paper
would be what
you are looking for.
A vet who does a fair amount of ultrasound in ferrets in the
Washington D.C. area would be Dr. Jean Wardell, Austin Vet
Clinic,
7323 Little River Turnpike,Annandale, VA, 22003,
703-941-5300, and
she may be of help in this pursuit.
With kindest regards,
Bruce Williams, DVM
