Constrictive pericarditis: New aspects

The current status of constrictive pericarditis is reviewed with regard to its etiology, physical signs, electrocardiographic findings and hemodynamic features. Angiographic aspects are also presented. The role and limitations of M-mode echocardiography in this disease are emphasized. The value of other noninvasive studies such as measurement of systolic time intervals, myocardial scanning and high-speed echocardiography is described. Emphasis is placed on the invasive and noninvasive methods that may be useful in separating restrictive cardiomyopathy from constrictive pericarditis. Methods of treatment, indications for pericardial resection and the current operative results are commented on briefly.
