Patients with Left Ventricular Thrombus Despite Normal Systolic Function.

The formation of a thrombus in the left ventricle (LV) in patients with normal systolic function is very rare. We report a case and identified 31 other adult patients who had an LV thrombus with normal LV systolic function. The median (IQR) age of these patients was 43 [37,59] years with a slight male predominance (59%). The vast majority of patients presented with embolic complications (28; 88%) with 3 of the other patients presenting with a febrile illness. Most of the cases occurred in the setting of an identifiable medical condition that carries an increased risk of thrombosis including inflammatory diseases, malignancies or hypereosinophilia. Treatment generally included anticoagulation with or without surgical removal or systemic thrombolysis. Recurrence of LV thrombus and/or embolic events have been reported in patients with LV thrombus and normal LV systolic function suggesting that long term anticoagulation may be needed.
