A 13-year-old walrus, which suffered from respiratory failure for about 10 months, became recumbency and died. Necropsy revealed severe congestion in various organs, firm lungs with marked interstitial emphysema, presence of whitish foamy fluid in the broncho-tracheal lumina, nutmeg liver and dilated right ventricle with thinned wall. Histological examination revealed marked congestion in various organs, chronic congestive pulmonary edema and congestive liver, which suggested systemic circulatory failure. In the heart, various sized wavy myocardial fibers as well as interstitial edema was observed; occasional necrosis of myocardial fibers associated with calcification were scattered in this lesion. Cause of systemic circulatory failure in the present warlus was discussed.
