case_images: Pre- and postintervention imaging findings. (A) Coronary angiography (CAG) demonstrating tubular eccentric 80% stenosis at the proximal portion of the left main coronary artery (LM). (B) Intravascular ultrasound (IVUS) demonstrating significant luminal narrowing of the proximal portion of the LM. (C) CAG demonstrating well-expanded sirolimus-eluting stent in the LM. (D) IVUS demonstrating optimal stent expansion and apposition to the vessel wall at the ostium of the LM.

case_images: At that time, coronary angiography (CAG) revealed an 80% stenosis at the ostium of the LM (Fig. 1A), and the minimal luminal area was 4.2 mm2 on intravascular ultrasound (IVUS) (Fig. 1B). Thereafter, both CAG and IVUS showed optimal stent expansion and apposition to the vessel wall (Fig. 1C and 1D).
case_images: Migrated coronary sirolimus-eluting stent (SES) in the right deep femoral artery (RDFA). (A) A lower extremity fluoroscopy demonstrating the SES (arrow) that had migrated from the left main coronary artery to the RDFA. (B) Intravascular ultrasound performed in the RDFA demonstrating decreased stent diameter and area with deformation of the proximal edge of the migrated SES.

case_images: Two years later, cardiac computed tomography performed at his hospital visit with symptoms revealed the absence of the SES in the LM, and the SES was found in the RDFA on fluoroscopy (Fig. 2A). IVUS performed in the RDFA showed a decreased stent area at the proximal edge of the migrated SES (Fig. 2B).
