Abstract
Introduction Identification of left ventricular thrombus (LVT) affects clinical management of at risk patients. Contrastenhanced MRI (CE-MRI) identifies LVT based on tissue characteristics and has been validated as a highly sensitive technique that improves LVT detection vs non-contrast echocardiography. However, prior comparative studies were performed without echo contrast agents, which facilitate LVT detection by improving LV cavity delineation.

Identification of left ventricular thrombus (LVT) affects clinical management of at risk patients
We studied diagnostic performance of contrast (C-ECH) and non-contrast (NC-ECH) echocardiography vs a reference of Contrastenhanced MRI (CE-MRI) LVT detection
Pts with LVT by CE-MRI had larger transmural scar size (26 vs 16% LV segments, p = 0.001), lower EF (29% vs 40%, p = 0.001), and higher wall motion score index (2.3 vs 1.6, p < 0.01) than patients without LVT
