Computed tomography in constrictive pericardial disease.

Thirteen patients with pericardial abnormalities and a question of constrictive hemodynamics underwent contrast enhanced cardiac computed tomography (CT). Those with clinical and catheterization evidence of restricted cardiac filling demonstrated three CT signs: a dilated IVC, a deformed ventricular contour, and an angulated interventricular septum. Patients with pericardial fluid, thickening, or calcification but without evidence of constriction showed none of these signs. Cardiac CT also defined sites of particular constriction for subsequent resection.

The visualized interventricular septum on cardiac computed tomography: a clue to the presence of severe anemia.

Severe anemia (10 g hemoglobin or less) will provide sufficient negative contrast on computed tomography (CT) to visualize the intracardiac chambers or lumina of large blood vessels. In the presence of secondary hemochromatosis, imaging of the interventricular septum can be due to excess cardiac iron (hemochromatotic cardiomyopathy) or the underlying transfusion-dependent anemia. Five percent glucose/water may be a satisfactory negative contrast agent for cardiac CT.
