Uhl’s Anomaly in a Domestic Shorthair Cat

Abstract

A 2-year-old, neutered male, domestic shorthair cat was presented for investigation of dyspnea and episodic weakness. Clinical and ultrasonographic features were consistent with right ventricular cardiomyopathy. Pathological findings documented Uhl’s anomaly. Although rare, Uhl’s anomaly should be a differential diagnosis for cats with right-sided congestive heart failure. In particular, Uhl’s anomaly could be misdiagnosed as arrhythmogenic right ventricular cardiomyopathy due to the similarity of clinical and echocardiographic findings.
