Abstract

The Japanese Heart Rhythm Society established a nationwide, mandatory, multi-center, prospective, observational registry of transvenous lead extraction (TLE) named the Japanese lead extraction registry (J-LEX) in 2018. We have published the first annual report of J-LEX with 661 cases from 42 hospitals. The second annual report of J-LEX in 2020 enrolled increased numbers of 785 cases from 75 hospitals. TLE procedure was attempted on patients with an average age of 71.7 years old, male in 72.5% in the hybrid operating room in 57.9%, and in standard OR with a C-arm fluoroscope in 18.7%. The indication of TLE was an infection in 62.8% and the guideline classification was class-I in 67.4% and class-IIa in 23.8%. The average implantation duration of target leads was 7.9 years. Complete removal was achieved in 96.6% of the target leads and clinical success in 98.1% of the patients. Perioperative complications were observed in 7.1% of the patients. One patient died during a TLE operation and the other three patients died in-hospital (cardiac death in one patient and non-cardiac in two patients). Although the annual J-LEX report in 2020 demonstrated an increased number of TLE procedures despite the first pandemic year of coronavirus disease-2019 (COVID-19), perioperative complications increased a little in comparison with J-LEX 2019.
