Why the study?
Does computed tomography improve the identification of intracardiac thrombus compared to cross-sectional echocardiography in patients with predisposing conditions?
Does computed tomography improve the identification of intracardiac thrombus compared to cross-sectional echocardiography in patients with predisposing conditions?
Computed tomography is more sensitive than cross-sectional echocardiography for detecting intracardiac thrombi, particularly in the left atrium, and can differentiate between new and organized thrombi based on density.
CT may detect more intracardiac thrombi than echocardiography; leaves open prospective outcome impact in Level 4 data.
Thirty-eight patients with conditions predisposing to intracardiac thrombus have been studied by computed tomography and cross-sectional echocardiography. Computed tomography identified 22 cases of intracardiac thrombus (13 left ventricular, eight left atrial and one right atrial). Cross-sectional echocardiography identified five of these left ventricular thrombi and the right atrial thrombus, but none of the left atrial thrombi. In addition, measurements of thrombus density on computed tomography identified a significant difference (p less than 0.02) between the density of a new compared with an organized thrombus.
