ABSTRACT
AIMS: Non-laser-based methods are safe in lead extraction but in the past have been less effective than laser methods. In the past decade, new equipment has been introduced including the Evolution® Mechanical Dilator Sheath and the Evolution® RL. We sought to determine the impact of new equipment on outcome in mechanical lead extraction. METHODS AND RESULTS: We considered 288 consecutive patients (age 66 ± 18 years) who underwent transvenous lead extraction (TLE) of 522 leads in the decade to the end of 2014. Three groups were identified: Group 1 (pre-Evolution® period, 76 patients, 133 leads), Group 2 (original Evolution® period, 115 patients, 221 leads), and Group 3 (Evolution® RL period, 97 patients, 168 leads). The age of leads was significantly greater in Groups 2 and 3 (6.2 ± 4.4 and 6.1 ± 5.4 years vs.4.7 ± 4.5, P < 0.05) as was the proportion of implantable cardioverter defibrillator leads (27.2 and 28.9 vs. 14.3%, P < 0.05). The groups were similar in the number of leads extracted per patient. Despite the increasing complexity of the systems extracted, complete extraction was achieved in a progressively greater proportion of leads (88.0% in Group 1, 95.5% in Group 2, and 97.6% in Group 3, P < 0.05), and procedure duration was similar. The proportion of leads for which femoral access was required was greater in Group 3 (11%, 18/164) compared with Group 2 (3%, 7/211), P = 0.006. The only major complications were a post-procedure subacute tamponade in Group 1 and an oesophageal injury related to transoesophageal echocardiography in Group 3. CONCLUSION: With current equipment, mechanical extraction provides a good combination of efficacy and safety.
