[Constrictive pericarditis]

Abstract

Etiology of constrictive pericarditis is diversified. In recent years the role of viral and iatrogenic factors (X-ray therapy, cardiac surgery) has increased. Clinical manifestations, including subjective complaints, resemble those in congestive heart failure although the mechanism of hemodynamic disorders is different--namely impairment of ventricular filling and diastolic performance. One encounters major difficulties while differentiating constrictive pericarditis from restrictive cardiomyopathy. In some patients conservative treatment is effective, in a majority of them surgical operation, pericardiectomy is the treatment of choice.
