Transvenous lead extractions in a single high-volume center over a 24-year period: High success rate and low complication rate

BACKGROUND: Transvenous lead extraction (TLE) procedures can be complicated and are associated with a small but significant risk of cardiovascular complications. However, methods and tools vary among centers. OBJECTIVE: The purpose of this study was to the present the methods and results of pacemaker and implantable cardioverter-defibrillator TLE procedures in our center over a 24-year period. METHODS: From April 1997 through 2020, we attempted to extract 2964 leads in 1780 procedures and 1642 patients. We mainly utilized single sheath technique using snaring or mechanical rotational sheaths and steel sheaths when necessary. Difficult procedures were performed by an experienced cardiologist, and close supervision was emphasized. Most of the extractions were performed using local anesthesia with sedation. RESULTS: Median age of patients was 65.0 [interquartile range 20.00] years, and median dwelling time of leads was 5.0 [7.0] years. Clinical success was achieved in 1739 procedures (97.7%) and complete technical success in 2841 leads (95.8%). Clinical success (leaving <4 cm of the lead in the body and achieving the clinical goal for the patient) was achieved for 79 leads (2.7%). TLE failed in 44 leads (1.1%) and 41 procedures (2.3%) among 36 patients (2.2%). There were 23 cases (1.3%) of major complications, with only 1 death directly related to the procedure (<0.1%). In addition, 2 patients with sepsis died within the first 24 hours after the procedure. No caval tears occurred. CONCLUSION: Single sheath lead extractions utilizing snaring or mechanical rotational sheaths were effective and safe in our high-volume center as performed by experienced operators.
