10 year old cat, presented for evaluation of profound weight loss (~6 pounds) despite good appetite.
-Briefly anesthetized for FNA of mesenteric lymph nodes
-Developed severe tachyarrhythmia after several minutes (presumed a-fib) which spontaneously resolved after 30 minutes with no treatment aside from blow-by oxygen.
-FNA were non-diagnostic although I did see 4-5 lymphoblasts among the hemodiluted sample so I am still thinking lymphoma

-My questions are about the heart. The LA:Ao is obviously increased and there is mitral regurgitation. The long-axis images are quite poor (sorry!) but I wanted to see if you could comment on how much of this is due to an underlying presumed cardiomyopathy that was uncovered by the propofol.
Thanks again,
Suzanne

Hi!
The arrhythmia is really
Hi!
The arrhythmia is really scaring – do you have an ECG of this?
Difficult to diagnose a specific cardiomyopathy here… The IVS appears thickened, the free wall is apparently normal. The left atrium is a bit enlarged. I would rule out thyreotoxicosis first (thyreoid storm…) and I would check the electrolytes. Even if the heart rate returned to normal, a Holter-ECG would be clearly indicated to see if this tachycardia appears frequently.The mitral regurgitation could be caused by valvular degeneration or SAM.
Best regards!

Given the tachyarrythmia in
Given the tachyarrythmia in my experience the LA is always a bit larger than normal with clinically significant arrythmias owing to diminished cardiac function.

What was the anesthesia
What was the anesthesia protocol as drugs used may have triggered the tachyarrhythmia?
He is a ~6.5 pound cat. He
He is a ~6.5 pound cat. He got 2 ml propofol IV over several minutes and no other drugs.
I rechecked him today. I don’t have the images uploaded yet but it was amazing what a difference there is. The arrhythmia has resolved although the rate is high. ECG showed sinus tachycardia (HR ~260 bpm). I did get the EKG from Monday and can upload it if there is interest. THe LA:Ao appears normal today. There is still some mitral regurgitation. I did not note SAM.
The owner does not want to pursue much more with this cat. I still think he will end up being a lymphoma cat (he has lost 6 pounds over the last few months).
Thanks!
