Pericardial Effusion in Cats

Davidson, B. J., A. C. Paling, et al. (2008). “Disease association and clinical assessment of feline pericardial effusion.” J Am Anim Hosp Assoc 44(1): 5-9.

Records of 83 cats with pericardial effusion diagnosed at Washington State University and the University of California (Davis) were reviewed to determine the main causes and clinical significance. The most common causes were hypertrophic cardiomyopathy (HCM) with congestive heart failure, cancer, and systemic infection. Most affected cats also had pleural effusion or pulmonary edema and signs of respiratory disease. Pericardial effusion is infrequent in cats, but is associated with serious cardiac and non-cardiac disease when it occurs and so warrants careful investigation.
