Abstract

Abstract: Background: Transvenous lead extraction (TLE) is an established procedure for the management of cardiovascular implantable electronic devices. However, some difficulties and risks of complications still exist, especially in old and adhered leads. Evolution RL (Cook Medical, Bloomington, IN, USA) is a newly introduced device for TLE; however, no clinical results have been reported in Japan, and the results with older leads are unknown. We investigated the efficacy and safety of Evolution RL and its usefulness for old leads at two TLE centers in Japan. Methods: A total of 27 consecutive patients who underwent lead extraction using Evolution RL at Shinshu University Hospital and Tokyo Women's Medical University Hospital from September 2017 to December 2019 were retrospectively enrolled. We examined the backgrounds of the patients and leads and investigated the efficacy and safety of the procedures. We divided the leads into two groups according to the number of years of implantation (10 years) and compared the results. Results: Among the 27 patients, 20 (74.1%) were men, and the median age was 62 (14–91) years. The total number of leads was 58, and the median implantation duration was 136 months (8–448). We achieved clinical success in all patients and complete procedural success in 24 patients (88.9%). In three patients, the broken tip of the lead remained in the heart. No major complications were noted. Of the 58 leads, there were 34 leads with more than 10 years of implantation, with significantly more Evolution RLs used (94.1% vs. 54.2%, p = 0.001) and significantly higher percentages of Evolution 11Fr, 13Fr, and steady sheaths used (79.4% vs. 33.3%, p = 0.001, 52.9% vs. 16.7%, p = 0.006, and 64.7% vs. 20.8%, p = 0.001, respectively). Conclusions: In two TLE centers in Japan, Evolution RL was shown to be safe and effective, even in leads older than 10 years. Graphical abstract: Unlabelled Image Highlights: Transvenous lead extraction (TLE) for the old leads is still challenging. We did a retrospective observational study in the two TLE centers in Japan. Evolution RL was useful and safe for TLE in old leads. For older leads, the larger diameter Evolution RL and steady sheath were used.
