[Cardiac constriction syndromes].
This article focuses on syndromes associated with cardiac constriction (i.e., constrictive pericarditis). These include classic chronic constrictive pericarditis, subacute <<elastic>> constriction including effusive-constrictive pericarditis, transient cardiac constriction, and occult constrictive pericarditis, all of which have their own clinical and developmental peculiarities. Establishing clinical suspicion is the basic first step in making a diagnosis, which can subsequently be confirmed by careful interpretation of imaging studies. With pericardial calcification, a simple chest radiograph may be sufficient; in other cases, Doppler echocardiography or chest computed tomography are necessary. The diagnosis of effusive-constrictive pericarditis requires cardiac catheterization combined with pericardiocentesis and the recording of intracavitary and intrapericardial pressures both before and after pericardiocentesis. It should be remembered that spontaneous regression is possible in some forms of constrictive pericarditis, particularly those that appear during the resolution of acute idiopathic pericarditis with effusion or that develop after cardiac surgery. Finally, there are only a few reports in the literature about occult constrictive pericarditis and its diagnosis is problematic.
