Left ventricular thrombus.


Left ventricular thrombus is seen in the setting of reduced wall motion and is associated with myocardial infarction (MI), cardiomyopathy, and ventricular aneurysm. It is commonly associated with anterior MI, where it occurs in 30-40% of cases, compared to <5% in inferior MI. Fifty-five to 85% of thrombi resolve within 3 years untreated, but the presence of thrombus increases risk for thromboembolic event, and observational studies suggest some benefit in prevention of thromboembolism with warfarin treatment.
