Value of cardiac ultrafast computed tomography for detecting right atrial thrombi in chronic atrial fibrillation.
We evaluated the accuracy of cardiac ultrafast computed tomography in diagnosing atrial thrombi in 70 patients with chronic atrial fibrillation, and identified the predictors of atrial thrombi from among clinical, echocardiographic, and ultrafast computed tomographic features. Ultrafast computed tomography identified 11 atrial thrombi in 9 patients: 4 patients had thrombi in the left atrium, 3 in the right, and 2 in both. Transthoracic echocardiography detected only 4 left atrial thrombi, and enlargement of the left or right atrium was associated with atrial thrombi (p <0.05).
