Chronic constrictive pericarditis is a difficult diagnosis and may present atypically. The authors report three clinical cases and review the diagnostic strategy of constrictive pericarditis. In these three patients, the diagnosis was finally made after one or more years of symptomatic disease and after several diagnostic work ups and ineffective treatments. In cardiac failure, pericardial calcification is often not observed on chest X-ray and Doppler echocardiography is usually the diagnostic investigation. Adiastole presents with dilatation of the vena cava and atria, contrasting with normal ventricles without major valvular disease. Doppler echocardiography enables distinction of constrictive pericarditis from restrictive cardiomyopathy: normal myocardium, thickened pericardium, specific septal motion, inspiratory increase in right ventricular dimensions, premature opening of the pulmonary valve, important variations in ventricular filling with respiration, expiratory diastolic reflux in the hepatic veins. Catheterisation confirms adiastole and may suggest a pericardial aetiology in characteristic cases, associated with only mild increases in pulmonary artery pressure. If need be, the pericardial thickening > 4 mm may be observed with magnetic nuclear resonance imaging and, when a doubt remains with respect to the diagnosis of cardiomyopathy, the absence of fibrosis on endomyocardial biopsy provides the diagnosis and indication for curative surgery: pericardectomy.

Chronic constrictive pericarditis (CP) is a relatively rare condition in which the pericardium becomes fibrotic and noncompliant, eventually resulting in heart failure due to impaired ventricular filling. The only curative treatment is pericardiectomy. Classically, CP does not usually cause severe pulmonary hypertension. When attempting to differentiate CP from restrictive cardiomyopathy, the presence of severely elevated pulmonary arterial pressure is used as a diagnostic criterion ruling against CP. We present a case of proven recurrent pericardial constriction following pericardiectomy presenting with severe pulmonary hypertension.

Chronic constrictive pericarditis is a rare condition characterized by an impairment of myocardial relaxation due to limitation by a rigid pericardium. It is most often associated with infection, thoracic radiotherapy and heart surgery. Clinical features are that of chronic heart failure, therefore non-specific and resulting in a delay of several years before diagnosis is made. The echocardiogram and heart catheterization are part of the initial work-up. Surgical treatment consisting in pericardiectomy can be curative if the disease is recognised early. This article makes use of a case report and review of the litterature to discuss the physiopathology, clinical features and management of chronic constrictive pericarditis.
