4 year old Sphinx heart

Hello

This is Frisbee a 4 year old Sphinx with a grade 3-4 HM in desparate need of a dentistry to remove the last few offending teeth that have not fallen out.

We attempted to perform a Pre-anesthetic echo and got some moderate images without sedation. Very wiggly.

The measurements for the all chambers were high with the the Lt atrium appearing dilated as well as the Rt atrium.

The ventricular walls appeared thickened. The doppler shows regurge at the TV and MV around 2m/s and BPs were 150/115.

Cat is not clinical. When discussing with the owner we suggested that we are in B1 and we would get an opinion on his case.

So the questions are: Can you subjectively place this cat in B1 or B2 based on the images and history or would it require a full consult for that determination?

And if the cat is in B1 and clinically doing well can it undergo a safe GA (considering all anesthetic precautions are followed)?

If the cat is in B2 would we instill therapy for a certain time and then proceed to the anesthetic?

To get better images and doppler readings we would require a sedation and repeat the echo.

Thanks. Brent

Hi!
The left atrium does not

Hi!

The left atrium does not look too large to me. On 4 chamber views the syst. diameter is < 15 mm which is normal. 

I would not stage a cat into B1 or B2, I use these stages only for dogs with mitral valve disease.

If the cat has cardiomyopathy which would need a full echo for me to decide, the disease would be compensated at this time (no left atrial enlargement, no sign of CHF)

Best regards!

Great info thanks. 
What

Great info thanks. 

What guidelines do you use to start therapy in a cat with cardiomyopathy?

Thanks. Brent

EL

LA needs to be in the > 1.5

LA needs to be in the > 1.5 cm + range to even consider therapy but more in the > 1.6 or 1.7 cm typically …but dpeends on cat to cat and other morphology and dynamics.

This heart looks normal other than a minor thickening of the MV. Any infectious history? Bartonella?

No issue with anesthesia for me… torb premed, propofol induction, iso maintenance is the safets protocol i know of…. as long as not hypertensive or hyperthyroid no contraindications that I can see to anesthesia.
