Difficulties in diagnosing chronic constrictive pericarditis.

This presentation calls attention to the many problems involved in the positive, aetiological and differential diagnosis of chronic constrictive pericarditis. We mention the difficulties in aetiological diagnosis in the absence of an episode of acute pericarditis in the past medical history and the clinical findings similar to vascular decompensated cirrhosis or idiopathic restrictive cardiomyopathy. ECG and two-dimensional echocardiography do not have an important role in diagnosis, and in the absence of computed tomography and magnetic resonance imaging, chest radiography, especially a lateral view, could establish the diagnosis. A delay in diagnosis creates difficulties in the surgical treatment, but this treatment improves the patient's condition in the long term more than the short term.
