Plain-English summary
A Fila Brasileiro dog experienced fainting spells and an irregular heartbeat, which led to a series of heart tests including an electrocardiogram and echocardiogram. These tests revealed issues like premature heartbeats and changes in heart size and function. Unfortunately, the dog passed away, and a postmortem exam showed significant heart enlargement and damage. The findings indicated a rare heart condition called left-dominant arrhythmogenic cardiomyopathy, which has not been previously documented in dogs.

Abstract
Background: In human medicine, arrhythmogenic left ventricular cardiomyopathy was described as a primary disease of the heart characterized by fibroadipose replacement of the myocardium.. Case Description: We report the case of a dog, with history of syncope and irregular cardiac rhythm. Electrocardiogram, echocardiography, and a 24-hour Holter monitoring showed, respectively, the presence of premature ventricular complexes with right bundle branch block morphology, an increase of the left ventricle end-diastolic diameter with preserved fractional shortening and ejection fraction, and a sinus arrhythmia as baseline rhythm with supraventricular tachycardia episodes and ventricular complexes with left bundle branch block morphology. After the death of the canine, a postmortem examination showed cardiomegaly. Fibroadipose replacement of the septum and both ventricles, with left ventricle myocardial fibrosis, suggestive of previous necrosis, was observed. Conclusion: These findings are suggestive of left-dominant arrhythmogenic cardiomyopathy which, to the best of our knowledge, has not been described in veterinary medicine.
