FELINE HYPERTROPHIC CARDIOMYOPATHY: CASE REPORT (Atena Editora)

Abstract

In domestic felines, cardiomyopathies are identified as structural and functional diseases of the heart muscle, among them, hypertrophic cardiomyopathy is the most prevalent, characterized by thickening of the left ventricle, which can vary from mild to severe, with diastolic dysfunction. Cats as young as three months old, with no sex or breed predilection, may be affected. Mutations in contractile protein genes, generating dysfunctional sarcomeres, have already been described in some pure breeds, therefore it can be considered a primary hereditary disease. Clinical signs are usually associated with dyspnea as a result of pulmonary edema and/or pleural effusion, in addition to the possibility of paresis or quadriplegia of the limbs as a result of arterial thrombi. The diagnosis has the echocardiographic examination as the gold standard. This work aims to describe the clinical signs, diagnosis and therapeutic approach of a young feline, mixed breed, 2 years old, with Hypertrophic Cardiomyopathy, attended at the Animal Health Unit Hospital Victória in the city of Porto Alegre, RS.
