ABSTRACT
Objective: To explore the safety and efficacy of a novel lead locking device (LLD) in the procedure of cardiac lead extraction for heart rhythm implants. Methods: A total of 6 patients using LLD for cardiac lead extraction in our hospital were retrospectively reviewed. Clinical parameters, the reason of cardiac lead extraction, lead locking stylet condition, outcome of lead extraction and operative complications were summarized. Results: There were 6 patients including 1 female with the median age at 62.5 years. LLD was used and 13 cardiac leads were extracted including 1 scrap electrode wire and 12 functional electrode wire. Among those, LLD was successfully inserted and locked on the top of 11/13 (85%) leads for whole procedure and 2 (15%) leads were not locked for whole procedure; 12 (92 %) leads were completely removed and 1 (8%) lead was partially removed. No severe complications occurred. Conclusion: The novel LLD may safely and effectively extract electrode lead which is beneficial for complete cardiac lead extraction.
