Successful coronary sinus left ventricular lead extraction 9 years postimplantation using the wire ThRoUgh Snare Twice (wire TRUST) technique.

The newly-proposed tandem approach, Wire ThRoUgh Snare Twice (Wire TRUST) is effective for grasping a lead with inaccessible ends. This case report shows that Wire TRUST can also enable successful extraction of a left ventricular lead by iteratively grasping and repositioning to the distal portion of the lead.

Wire ThRoUgh Snare Twice (Wire TRUST) technique: A novel method to grasp a lead with inaccessible ends as a supportive femoral approach for transvenous lead extraction.

INTRODUCTION: Transvenous lead extraction (TLE) is a crucial procedure for managing cardiac implantable electronic devices. The use of a combined superior and femoral approach has been found to enhance the success rate of TLE. This report introduces a novel technique, named "Wire ThRoUgh Snare Twice" (Wire TRUST), for effectively grasping a lead without a free end during TLE. METHOD: The Wire TRUST technique was applied in a case involving a 49-year-old male patient requiring TLE due to electrical artifact on the right ventricular (RV) lead, replacement of the RV lead, and pacemaker generator exchange. The Wire TRUST technique involved the insertion of a 4-Fr pigtail catheter and a 6-Fr snare catheter through the 14-Fr sheath inserted from the right common femoral vein. The 4-Fr pigtail catheter was hooked to the RV lead under multidirectional fluoroscopic guidance in the right atrium. The 0.014-in. guidewire was advanced through the pigtail catheter, crossing the RV lead until reaching the inferior vena cava. Subsequently, the distal end of the 0.014-in. guidewire was captured using a snare and pulled, facilitating externalization of the guidewire. After externalization, both ends of the 0.014-in. guidewire were passed through the snare outside the body and reinserted into the 14-Fr sheath. By simultaneously advancing and closing the snare while applying tension to the 0.014-in. guidewire, a secure grip on the lead without free ends was achieved. RESULTS: The Wire TRUST technique enabled successful lead extraction and replacement without any complications. The technique facilitated the co-axial alignment of the powered sheath with the RV lead, ensuring safe and efficient extraction. CONCLUSION: The Wire TRUST technique presents a novel and effective approach for grasping leads with inaccessible ends during TLE.
