It means she has very mild heart disease that probably won't affect her

IVSd, LVPWd, LA diameter and keep a close watch on the SAM/mitral
regurgitation. Some cats develop SAM before the LVPW and/or IVS start to
thicken- and some cats only develop SAM-- without any wall thickening at
all. SAM leads to mitral regurgation that could lead to heart failure if it
becomes severe enough. But Atenolol should keep the SAM in check.

The vet might be using >5 mm as the threshold for hyperthrophy - or the
regional thickening of the IVS- or the mild thickening of the mitral valve
leaflet - or the mild LVOT obstruction.

I'm sorry I can't be more helpful. I'm not trying to blow you off-- its
just that her heart disease is so mild that there's really not much I can
comment on.
Let me know how her next exam goes, ok?
Best of luck,
Phil

Thanks for your response, Phil. It seems it's very encouraging that
you have little to comment on--I'm glad to hear that in your
estimation her heart condition is very mild. She has a recheck in 3
months and another echo in six months. I realize the results of the
second echo are key--that will show whether there is any progression.
The vet said that in his experience, most cats are stabilized with
medication. So I'm hopeful that's the case with her. The vet did say
he could no longer hear the heart murmur so I assume that since it's
the mitral regurgitation causing that, the atenolol is controlling it.
Thanks again--I am very relieved. I'll post the results of her next
checkup and echo.
