Objective Intracardiac thrombi are intermittently come across on cardiac computed tomography angiography (CCTA). This study aimed to examine the prevalence, outcome, and prognosis in patients with incidental found left-sided cardiac thrombi on CCTA. Material and Methods The Ethics Committee approved the present study of the Faculty of Medicine, Khon Kaen University, Khon Kaen, Thailand. A retrospective review of CCTA was performed for incidental left-sided cardiac thrombi. Results A total of 1080 CCTAs were enrolled with the prevalence of incidental left-sided cardiac thrombi is 4.53%. Of the 49 patients with CCTA incidental left-sided cardiac thrombi, 16 had left atrial thrombi, and 33 had left ventricular thrombi. All thrombi were undetermined before the CCTA, and their identification subsequently generated anticoagulation treatment. In 10 patients, embolic complications happened, 4 of which were fatal. Patients with incidental detected left-sided intracardiac thrombi seen by CCTA had more embolic event than patients who did not discover left-sided intracardiac thrombi by CCTA (HR = 8.07; 95% CI 1.48–44.06; p = 0.016). Conclusions Incidental left-sided cardiac thrombi on CCTA guided to management adjustments and seemed to present substantial mortality and morbidity in the present study. Physicians who interpret CCTA should ensure a dedicated effort not to disregard these prospective pitfalls.
