The case of a 3-year-old dog with idiopathic constrictive pericarditis has been described. Constrictive pericarditis is an uncommonly reported disease in veterinary medicine. The etiology in many cases is unclear. The most common etiologies of this disorder are viral, pericarditis, renal failure, tuberculosis, radiation therapy, collagen vascular disease, prior pericardiectomy, and idiopathic. Constrictive paricarditis is an outcome of a subacute process which develops signs of a chronic, resistant to medical treatment, progressive and devastating right ventricular heart failure, and its progression depends on hemodynamic circulatory changes.
