Abstract

Incidental left-sided cardiac thrombi are occasionally encountered on CT. This study examined clinical findings and outcome in patients with incidental cardiac thrombi on CT. Our image database was reviewed for incidental left-sided cardiac thrombi on CT. These patients' charts were retrospectively reviewed. Thirty-five patients had incidental left-sided cardiac thrombi on CT, 26 of which were ventricular and 9 atrial. Thirty-two thrombi were unknown prior to the CT, and the radiologist interpretation triggered echocardiography or anticoagulation in most cases. Embolic complications occurred in 14 patients, 4 of which were fatal. Twelve patients had concomitant cancer, 6 of which were newly discovered. Incidental left-sided cardiac thrombi on CT appeared to confer substantial morbidity and mortality in our study. In many cases, the cardiac thrombi were new and led to changes in management. A high rate of malignancy was also noted, which may be related to the hypercoagulable state of malignancy.

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.

Atrial Filbrillation

Atrial fibrillation refers to the abnormal heart rhythm characterized by rapid and irregular beating of the atria. Here is the latest research.

Cancer Imaging

Imaging techniques, including CT and MR, have become essential to tumor detection, diagnosis, and monitoring. Here is the latest research on cancer imaging.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.
