case_images: Coronary angiography showed significant and hazy lesions in the proximal and midportion of the LAD (Red arrow). Therefore, PCI on the LAD was planned.

case_images: Coronary angiography was performed via right femoral artery access, revealing significant and hazy lesions in the proximal and mid-portion of the left anterior descending (LAD) artery (Figure 1). However, the guiding catheter was re-engaged, and the wire (BMW Universal II) was passed through the target point again (Figure 1A,B).
case_images: Stent crumpling was seen so that the proximal stent was folded on one side of the vessel (one edge was floating inside the lumen).

case_images: IVUS revealed stent crumpling so that the proximal stent folded on one side of the vessel, causing one edge to float inside the lumen (Figure 2).
case_images: (A, B) Following post-dilation, some filling defects seemed to be inside the stent (stent thrombosis), then slow flow was seen in LAD, which worsened rapidly.

case_images: The guidewire was exchanged from BMW to Sion Blue to correct the abluminal wire passage (Figure 3A,B).
case_images: (A) Angiography after new stent deployment (Supraflex 4 *20) and new post-dilation by non-compliant balloon (Sapphire 4*10). (B) Angiography confirmed TIMI flow III in LAD, and adequate expansion and apposition of the stent were confirmed.

case_images: Final angiography confirmed TIMI flow grade III in the LAD, with adequate stent expansion and apposition confirmed by IVUS (Figure 4).
