Abstract

A female Russian rat snake, Elaphe schrenckii, was presented for loss of movement. Physical examination showed the swelling in the area of heart. Radiographic examination revealed cardiomegaly, pericardial effusion, and a soft opacity in the area of swelling. Although pericardiocentesis to remove fluid out from the heart as well as vigorous treatments were given to the Russian rat snake, it died during treatments. Postmortem examination confirmed pericardial effusion of pale yellow, translucent fluid with mild dilation of the right atrium and ventricle. Formalin -fixed paraffin embedded tissue sections were stained with routine H&E and the classical von Kossa's method for histopathological demonstration. Histopathological examination revealed multifocal calcification in myocardium and consists of the displacement of muscular fiber by limy deposits. Congestive heart failure was suspicious for the snake when it was alive. In wild reptiles, muscle degeneration has been reported with nutrition disorders but the present case is the first report of myocardial degeneration in a Russian rat snake and contributes to the rare reports of cardiac disease in snakes.
