It was reported the procedure was to treat a lesion with moderate tortuosity and heavily calcification in the distal right coronary artery (rca).The balance middleweight (bmw) elite guide wire was advanced to the proximal circumflex artery with no issues and an unspecified stent was implanted.The guide wire was moved to the rca distal lesion into the posterior left ventricular (plv) branch.An unspecified stent was implanted successfully into the plv from the distal rca.After the procedure, the physician decided to try to re-wire through the mid stent to open the side cell of the stent in the posterior descending artery (pda); however, the guide wire did not cross through the existing stent implant and curled up in the proximal stent.After slight attempts to straighten the guide wire by pulling back the guide wire, it was decided to end the procedure.When the guide wire was withdrawn from the patient anatomy, it was noted that the distal end of the guide wire was detached and partially in the aorta.Attempts were made to snare the separated guide wire piece, but the guide wire dislodged and traveled to the subclavian and partially in the aorta.More attempts were made to snare the separated piece, but the separated guide wire piece traveled down to the iliac bifurcation.After a few more attempts, the separated piece was captured with a snare and withdrawn without any further complication.The patient recovered with no further problems.There was no adverse patient sequela.There was a significant delay in the procedure; however, it was not reported to be clinically significant.No additional information was provided.
