Dilated cardiomyopathy in a spider monkey (Ateles paniscus)

Background  A spider monkey with severe dyspnea was referred to our clinic. Methods and Results  Radiographs revealed an enlarged cardiac silhouette. Ventricular tachycardia and ST segment depression were also diagnosed after an ECG. These findings coupled with the postmortem examination confirmed dilatative cardiomyopathy. Conclusions  This case is worthy of presentation since dilatative cardiomyopathy has been rarely encountered in spider monkeys.
