This case report describes the concurrent presentation of arrhythmogenic right ventricular cardiomyopathy and hepatic lipidosis in a cat, suggesting a potential pathophysiological link through abnormal lipid metabolism.
Suggests possible right heart fibrofatty changes in feline hepatic lipidosis; leaves open causality and clinical relevance.
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 owners request. A postmortem histopathologic examination of the cats 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.
