Pericardial Effusion and Compressive Disorders of the Heart: Influence of New Technology on Unraveling its Pathophysiology and Hemodynamics.

Constrictive pericarditis and cardiac tamponade cause severe diastolic dysfunction, but do not depress systolic function until the agonal state has been reached. Multimodality cardiovascular imaging has brought the nuances of pericardial disease to the domain of the practicing cardiologist.
