Arrhythmogenic Right Ventricular Cardiomyopathy in a Cat with Hepatic Lipidosis

A Turkish angora cat with a one-week history of anorexia and vomiting was diagnosed with hepatic lipidosis. During hospitalization and treatment, the cat suddenly showed respiratory-related clinical signs, including coughing and dyspnea, 13 days after initial diagnosis. Due to the poor response to treatment, the patient was euthanized at the owner’s request. A postmortem histopathologic examination of the cat’s heart showed dilation and wall thinning of the right atrium and ventricle, with fibrofatty infiltration corresponding to an arrhythmogenic right ventricular cardiomyopathy (ARVC). This is a case report of ARVC concurrent with hepatic lipidosis in a cat; both diseases are related to disturbances in lipid metabolism.
