A 47-year-old man with chest tightness was transferred and diagnosed as having inferior acute myocardial infarction. The patient underwent an emergency coronary angiogram, which showed total occlusion at a proximal site in the right coronary artery (RCA) with an intact left coronary artery (Fig. 1A, Online Video 1). Percutaneous coronary intervention (PCI) was commenced. Surprisingly, a subsequent coronary angiogram showed different results, a newly visualized vessel (Fig. 1B, white arrows), which seemed to indicate that successful spontaneous recanalization might be achieved (Online Video 2). However, the possible ostium of the visualized vessel (red arrowhead) was separate from the tip of the guiding catheter (white arrowhead). Careful scrutiny of the angiogram revealed the visualized vessel was a coronary vein running parallel to the RCA that opened into the coronary sinus (black arrows). After PCI, the final angiogram showed the recanalized RCA, and the newly visualized vein had disappeared; it was a “phantom vessel” (Fig. 1C, Online Video 3).
