Abstract: A recent review of mortality in captive red pandas (Ailurus fulgens) listed cardiac pathology as the most common cause of death in the adult age group. The aim of this study was to describe the standard echocardiographic variables in 13 captive, healthy, adult red pandas that underwent an elective health examination. In addition, differences between the two subspecies of red panda, A. f. styani than in A. f. fulgens, and association of these echocardiographic variables with age, sex, and body condition score, were examined. Anesthesia was induced and maintained with isoflurane inhalant anesthetic. All animals underwent a full physical examination and comprehensive echocardiogram including 2D, M-mode, and Doppler modes of ultrasound examination. Mean and SD of the echocardiographic variables are reported. Systolic performance was considered subnormal due to the effect of the anesthetic agent. The echocardiographic variables were similar for the two subspecies and sexes, with the exception of the left atrial dimension (2D), which measured larger (P= 0.03) in A. f. styani than in A. f. fulgens, and left ventricular internal diameter in diastole, which measured larger (P = 0.04) in males than females. Several echocardiographic measurements were correlated with age (P < 0.05), whereas the only measurement that significantly correlated with body condition score was end diastolic volume (P = 0.01). These results provide ranges that can offer guidance for predicting cardiac disease in red panda.
