Reply To: Cardiac measurements under GA (what does the ga do?)

Liz Bode

That all sounds good. If they’re normal then it’s likely to be the case and I wouldn’t be too concerned. Fractional shortening is a poor marker of systolic function as it’s affected by so many variables so I’d rely more on chamber dimensions in this case and if the owner wants to pursue it I’d look at other markers of systolic function.

I have in my head (anecdotally) that I get a few advice requests with Labs and cardiac silhouette queries and they generally turn out to be normal. Occasionally we see tricuspid valve dysplasia/ mitral valve dysplasia or degeneration and sometimes DCM but relatively rare for the latter compared to other breeds. Always good to check it out though.
