– 6 yr old FS Havenese witha newly diagnosed heart murmur that rDVM thinks has gotten louder over a few weeks of diagnosing it
– grade 2-3/6 which I heard best on the left side
– dog has had a recent history of vomiting and fever (now better); bloodwork unremarkable; 4Dx results pending
– echo shows normal LA and good systolic function so I am not overly concerned about this heart
– mild TR with a max vel of about 2 m/s (underestimated); Pulmonary and aorta max vel both under 2m/s

– I don’t think I see MR and the mitral valves look relatively normal; no evidence of VSD
– does the RV wall look a little thick?
So why does this dog have a murmur? The TR is likely too mild to hear? This echo was performed with butorphanol/acepromazine/atropine sedation. The dog can be very nervous in the hospital. The rDVM was concerned about the possibility of endocarditis but I can’t see evidence of this. He placed the dog on an empirical course of clindamycin.

With a fever the murmur may
With a fever the murmur may just have been functional but is it persistent? Lust like some animals have a murmur under anesthesia but don’t when they are awake. Structurally the heart looks great so likely not an issue.
Just a thought. Do you have
Just a thought. Do you have PW of the LVOT and RVOT at the AV and PV? A functional murmur would show turbulence and not a laminar wave form. If the murmur is diastolic, then I would check (if you haven’t already) color flow across the AV valve in the RPSA for color during diastole. I doubt there will be any since there doesnt appear to be any lesions on the AV leaflets in your images.
And to your question regarding the RV free wall thickness, to me it looks normal.

Hi Tom
I did not do PW, just CW and colour flow on the LVOT and RVOT. I would assume you would see a “filled in” wave form as oppsed as an empty one with turbulance? I didn’t see AI in this study.
