Fig. 2 — Radiopaque marker dislodgement. (A) Fluoroscopy shows the distal migration of a foreign body (yellow arrow) as a cutting balloon (dotted line) advances into the left anterior descending artery (LAD) over the 0.014-in. guidewire. (B) A snare catheter (dotted line) with 7-Fr GuideLiner® V3 GEC support is advanced to the distal LAD, where the dislodged radiopaque marker (yellow arrow) of the Guideplus guide-extension catheter (GEC) is located, and successfully grasps it. The snare catheter and 0.014-in. guidewire are simultaneously pulled back into the GuideLiner® V3 GEC and completely retrieved. (C-F) Findings of the retrieved Guideplus GEC. (C) Deformed proximal port of Guideplus GEC. (D) Comparison of the Guideplus GEC in Case 1 and an unused one. (E) Fluoroscopy reveals the Guideplus GEC without a proximal radiopaque marker. (F) The dislodged radiopaque marker of the Guideplus GEC was retrieved using the snare catheter.
