Abstract:
An 8-year-old spayed female Maltese (2.5 kg of body weight) presented with the primary complaint of loud heart murmur and exercise intolerance. Diagnostic imaging revealed severe pulmonic stenosis (peak velocity 5.2 m/s) with right ventricular hypertrophy. The dog revisited after 2 years, at which time, diagnostic imaging revealed severe biventricular hypertrophy, dynamic left ventricular outflow tract obstruction, left atrial dilation and pulmonary hypertension with worsened pre-existing pulmonic stenosis. Postmortem investigation revealed hypertrophic cardiomyopathy and regional myocardial infarction. The case was diagnosed as hypertrophic cardiomyopathy secondary to severe right and left ventricular outflow tract obstruction.
