Antegrade wire crossing of a mid calcified left anterior descending (LAD) artery was achieved. However, the wire was seen deflecting in a different pathway than the angiographically anticipated course of the vessel. Therefore, the computed tomography images were reanalyzed and the wire was seen to be within the tented site of the left internal mammary artery to the LAD anastomosis and correctly positioned according to the vessel course.
