Good morning everyone.
I saw this young cat yesterday, 2 years old, with a grade III/VI left systolic murmur, heard along sternum. Cat has never presented respiratory issues.
I found the IVS and LVW to have mild concentric hypertrophy , there is turbulence in the LVOT but velocity is not obviously increased. The IVS appear to be quite irregular to me, and also there is mild subendocardial hyperechogenicity. I wonder if I underestimated velocity or this is not SAS.
Thanks for any input.

Looks like minor hcm but
Looks like minor hcm but compensated silvana. Often we can’t overtly find the turbulence in these cases but it is usually lvot outflow or mr causing the murmur.

Hi!
I don´t think that this
Hi!
I don´t think that this is a real SAS. SAS is a very rare finding in cats. I would rather think of a mild or early form of HCM. The heart murmur in these cats, as Eric wrote, is mostly a dynamic one, caused by systolic anterior motion of the anterior mitral valve leaflet. This doesn´t have to cause very high outflow velocities, but usually causes a dagger shaped profile (didn´t see this on your picures but would not rule it out). Another possibility is that the heart murmur has nothing to do with the concentric hypertrophy you saw. For instance, many cats show dynamic right ventricular outflow obstruction when they are stressed; this is a benign finding.
If you have a video (or more videos) feel free to post them!
