Figure 2 Validation of DE-CMR During Clinical Follow-Up

Stratification of patients with 6-month follow-up according to presence or absence of thrombus by DE-CMR yielded over a 7-fold difference in study end points (TIA, CVA, or pathology-verified thrombus) between groups (15.1% vs. 2.1%). Further stratification based on cine-CMR did not improve differentiation of patients. Details regarding the 8 patients who were DE-CMR–positive for thrombus and had clinical event or pathology confirmation are shown in the corresponding table (bottom). CVA = cerebrovascular accident; TIA = transient ischemic attack; other abbreviations as in Figure 1.
