A 50-year-old man with a recent embolic stroke was referred by a neurologist for abnormal electrocardiography results consistent with large anterior myocardial infarction. Echocardiogram results showed akinesis of the anteroapical left ventricular wall without obvious mural thrombus and an ejection fraction of 45%. There was no evidence of an intracardiac shunt. Coronary angiography revealed irregular linear filling defects in the mid left anterior descending artery (A) (line 1 and 2 indicate the length of optical coherence tomography pullback). Optical coherence tomography showed multiple channels surrounding a larger central lumen (B, arrowheads). The channels were seen to communicate both with each other and with the larger central lumen (D to G). Proximally and distally, they converged into a single lumen (C). Some residual thrombus was still visualized within the smaller channels (B, arrow). Although spontaneous recanalization occasionally is found in patients undergoing catheterization, this is the first in vivo demonstration of recanalized thrombus using intravascular optical coherence tomography.
