“…Radiofrequency catheter ablation (RFCA) is a minimally invasive technique targeting a tachyarrhythmic focus or reentrant circuit with radiofrequency energy to permanently disrupt that tachyarrhythmia . This procedure has been reported in a small number of dogs with APs . Study goals were (1) describe the clinical, electrocardiographic, echocardiographic, and electrophysiologic findings in a large consecutive series of dogs with APs and (2) report RFCA procedural and long‐term outcomes, with assessment of potential curative properties for RFCA in a clinical population of dogs.…”

BackgroundAtrioventricular accessory pathways (APs) in dogs have been reported rarely. Data regarding clinical presentation and long‐term outcome after radiofrequency catheter ablation (RFCA) are limited.Hypothesis/ObjectivesTo study clinical features, electrophysiologic characteristics, and outcome of RFCA in dogs with APs.AnimalsEighty‐nine dogs presented consecutively for RFCA of APs.MethodsCase series.ResultsLabrador retrievers (47.2% of dogs) and male dogs (67.4% of dogs) were most commonly affected. Labrador retrievers were more likely to be male than non‐Labrador breeds (P = .043). Clinical signs were nonspecific and most commonly included lethargy and gastrointestinal signs. Concealed APs were more prevalent in Labrador retrievers than other breeds (P = .001). Right‐sided APs (91.7%) predominated over left‐sided (8.3%). Tachycardia‐induced cardiomyopathy (TICM) occurred in 46.1% of dogs, with complete resolution or substantial improvement noted on one‐month postablation echocardiograms. Radiofrequency catheter ablation successfully eliminated AP conduction long term in 98.8% of dogs in which it was performed. Complications occurred in 5/89 dogs. Recurrence in 3 dogs was eliminated long term with a second procedure.Clinical Importance/ConclusionsAccessory pathways are challenging to recognize in dogs because of nonspecific clinical signs, frequency of concealed APs that show no evidence of their presence during sinus rhythm, and intermittent occurrence of tachyarrhythmias resulting from APs. Tachycardia‐induced cardiomyopathy commonly occurs with AP‐mediated tachycardias and should be considered in any dog presenting with a dilated cardiomyopathic phenotype because of its good long‐term prognosis with rhythm control. Radiofrequency catheter ablation is a highly effective method for eliminating AP conduction and providing long‐term resolution.

“…Usually, EPS is performed to evaluate abnormalities of the electrical conduction system of the heart, to test the influence of various chemicals and medicines on this system, and to develop novel methods or improve existing protocols of non-pharmacological treatments of arrhythmia. In the case of dogs, apart from experimental purposes, EPS is usually performed in order to choose an appropriate (pharmacological or non-pharmacological) treatment or prior to, radiofrequency (RF) ablation (Santilli et al 2006(Santilli et al , 2010a(Santilli et al , 2010b(Santilli et al , 2011(Santilli et al , 2013Perego et al 2012). To the best of our knowledge, determination of the electrophysiological conduction parameters for selected electrophysiological parameters of dogs was a subject of only few studies (Landmark & Amlie, 1976;Pickoff et al 1983;Huerta et al 1984;Sassine et al 1984;Young et al 1986;Timour et al 1987;Traunecker, 1988;Wright et al 1996).…”

Background: Invasive electrophysiology study (EPS) is one of the most important adjunct tests for the evaluation of arrhythmias in human medicine. However, EPS is neither well known nor widely used in veterinary medicine. Objective: To define the values for intracardiac conduction parameters determined during invasive EPS in dogs. Animals and methods: The study included 16 admitted dogs of various breeds, sex and ages and 6 control Beagles. In the Beagles, EPS was performed twice at 6-month intervals in order to verify the reproducibility of the results. Results: No significant differences were found between the results of the baseline and repeated EPS performed in the Beagles. We found retrograde conduction in 13 (59%) out of 22 dogs and including 4 (31%) animals with concomitant 'jumps' in the atrioventricular node conduction curve, pointing to the presence of dual conduction in this node. The mean values of the AV and retrograde VA Wenckebach points equaled to 220 and 360 ms, respectively, suggesting that the capability of the descending route is higher than that of the ascending route. Conclusion:The values determined in this study may be helpful in early detection of abnormalities in the electrical conduction system of the heart.
