Left Ventricle Arrhythmogenic Cardiomyopathy in Canines and Felines

Abstract

This chapter describes pathological, electrocardiographic, echocardiographic, and clinical findings of two cases, one in a canine and the other in a feline, which suggest the presence of Left Ventricle Arrhythmogenic Cardiomyopathy. It is considered to be of interest for comparative medicine. To the authors’ knowledge, it’s the first ever description of the pathology carried out in companion animals. The canine patient arrived at the clinic with arrhythmias. After 48 hours, he had a sudden death and the heart was studied, finding a partial replacement of the free wall and septum of the left ventricle with fatty tissue. The feline patient also had a sudden death, and the heart was studied, where transmural replacement of the myocardium from the free wall of the left ventricle was found, which was replaced by adipose tissue.
