I am in need of some references for ARVC. I have a 5 yr old s/f boxer who on annual exam had arrythmia.ECg showed VPC. Owner had echo done at Boxer show echo was normal. Owner did holter herself. Brought me results w/o cardiologist opinion 10,017 vpc 22pairs,3 triplets 2 runs. I want to read up on prognosis . We also have a digital mast cell tumor we are considering removing. I want to know how much trouble we are in and would like good recent reference is anyone has one.

From June Boon “Veterinary Echocardiography” second edition Wiley Blackwell p 400 with associated references:
Arrhythmogenic right ventricular cardiomyopathy is an infiltrative disease of the right ventricular myocardium. Fatty and fibrous infiltration leads to ventricular and supraventricular arrhythmias that often result in sudden death (1). This disease is reported in cats with echocardiographic manifestations that include pronounced right atrial and ventricular dilation, paradoxical septal motion, abnormal trabeulation of the right ventricular wall, and aneurysmal dilation of the right ventricular wall with akinetic and sykinetic muscle (1). The left side of the heart is essentially normal. Abnormalties of the left side when present include atrial dilation and abnormal fractional shortening in the presence of paradoxial septal motion. The left atrial dilation ranges from mild to severe in these cats (1).
Most affected dogs with ARVC have no detectable echpocadiographic abnormalties. Some Boxers, with arrhythmia, have left ventricular dysfunction, but it is not a common occurrence. Careful evaluation of the right side of the heart may show some enlargement and dysfunction, but this is a challenge (2)

I am sure you could probably find lots of info on the internet. Sounds like the MCT may be the least of this dogs problems.
This will most likely end in sudden death. Good luck. Did you do an Echo?
Awesome thanks I asked
Awesome thanks I asked because this owner came in with internet article that had prognostic indicators based on number of abnormal beats, runs etc. I will chase that down just didn’t get chance yet. I appreciate info. I did not get to do the echo they did echo at a boxer dog show with a cardiologist just basic study. They got the ho,lter from a boxer friend and ran it themselves,which has the obvious problem now of interpretation. I did speak to them about not having cardiologist in the loop I assume this may be common practice amongst the boxer community probably not best idea. The article was authored by Dr. Sanmarco sp? it was for laypersons I will look into if he has published work on it as well.Thanks again !!!
I guess if I were this owner
I guess if I were this owner I would not buy any green bananas for this dog. Common sense would tell us the worse the arrhythmia the higher chance of sudden death. I am curious if they saw any changes in the right side of the heart. Interested in the cardiologist report. Good luck.
