Hi all,
I’m stuck on this case. A 19 week old female entire DSH that was recently diagnosed with a grade III/VI heart murmur, pansystolic and point of maximal intensity is on the left side. The only problem is, i can’t find the murmur. Aortic flow velocity and pulmonic flow velocity were normal. LV measurements were all normal I could not see any mitral or tricuspid dysplasia. I also looked for ASD and VSD as well as DRVOTO. Have a missed something?

Hi!
The good thing is, you
Hi!
The good thing is, you are not the only one who has frustrating experiences like this one, also cardiologists sometimes have a hard time finding the origing of the murmurm in cats.
Fact is, the prevalence of heart murmurs in stressed cats is almost 2x the prevalence in non-stressed cats. Means that once the cat is in a comfortable position, the murmur can disappear.
Most of these murmurs are dynamic ones and need careful mapping of the RVOT and LVOT with PW-Doppler to find a dynamic flow acceleration (dagger-shaped profile). To rule out a VSD in a cat always look at short axis views of the left ventricle and the heart base. So-called supracristal defects and muscular defects can be missed on right parasternal long-axis views.
Hope this helps

Hi Pete,
Yes, that does help!
Hi Pete,
Yes, that does help! thank you so much:)
Good day from Melbourne!:)

You can also reduice your CF
You can also reduice your CF sampling size by about 1/2 of what you show here and the Cf will be more precise and get less body motion artifact.
