A 9-mo-old female blue duiker (Cephalophus monticola) weighing 3.9 kg was diagnosed with a cardiac murmur during quarantine examination. Evaluation of the heart by auscultation, electrocardiography, two-dimensional echocardiography, and Doppler color-flow echocardiography revealed a restrictive outlet ventricular septal defect with left atrial and left ventricular dilation. Trivial mitral, tricuspid, and aortic regurgitation was also noted. Though the duiker was clinically asymptomatic at the time of cardiac evaluation, it was found dead 1 wk later. The cause of death was not determined.
