Hello,

I posted this to the health+behav group, and someone suggested that I post
it here as well.

My cat Morag, who is a Burmese, was diagnosed with severe HCM by my regular
vet about a month ago after having undergone an ultrasound.  On Thursday she
saw a cardiologist at the veterinary hospital here, and after an ultrasound
was performed using a machine with a higher resolution than the one
previously used, the cardiologist said that she has a very unusual heart
condition that doesn't fit into any textbook.  She actually only has mild
HCM, but the problem is that her heart is abnormal.  Her left atrium is
huge, and her left ventricle is just abnormal.  The wall bulges inward in
several places and also the ventricle contains crap, stuff that strings from
one side of the chamber to the other.

The cardio says that she has seen perhaps a handful of cats in her career
with a presentation similar to Morag - the most interesting point she made
was that out of that handful of cats, the cat with the heart that most
closely resembles Morag's was also a Burmese.  So I'm wondering if anyone
has heard of this before in Burmese cats (or in any cat).
