Distal embolisation as a cause of ST-segment elevation myocardial infarction: insights from optical coherence tomography

Figure 1. Coronary angiography and OCT images after thrombus aspiration from the distal portion of the LAD. Initial coronary angiography (A, Moving image 1) showed total occlusion at the distal portion of the LAD (arrow). Coronary flow was recovered after thrombus aspiration (A’). OCT pullback was from distal to proximal of the LAD. OCT pullback was performed twice to investigate the long lesions of the LAD. The first pullback was from the distal to the middle portion and the second pullback was from the middle portion to the guiding catheter (Moving image 2, Moving image 3). At the proximal segment, there was ...
