Constrictive pericarditis.

Abstract

Constrictive pericarditis, although still a relatively rare disease, continues to be a clinical problem that most practicing cardiologists may encounter. A major clinical clue to diagnosis is the continued elevation of the central venous pressure after adequate diuresis. The diagnosis is further supported by (1) prominent X and Y descents in the jugular venous pulse, (2) a relatively normal or only slightly enlarged cardiac silhouette in a patient with congestive heart failure, (3) pericardial calcification or significant congestive failure especially when the right sided signs predominate without obvious cause. When the disease is suspected, appropriate investigation should be undertaken using both the noninvasive and the catheterization studies. If the diagnosis is supported, then the choice of therapy at present is based primarily on severity of symptoms with surgical removal of the constricting pericardium being the therapy of choice in patients unable to be managed medically.
