Clinical observation of removing more than 1 200 cardiac implantable electronic device leads with needle's eye snare
Objective To observe the safety and efficacy of the needle eye snare(NES)as a first-line tool for transvenous lead extraction(TLE).Methods The clinical data and TLE data of all patients in Peking University Peoples Hospital from January 2014 to January 2022 were retrospectively analyzed.The effects of device type,lead indwelling time,indication of infection on TLE outcomes and complications were observed and compared.Results A total of 593 consecutive patients[426 males;mean age(65.9±14.9)years]were included.The average indwell-ing time of all leads was 92(60,132)months,and the number of extracion leads was(2.1±0.7).The clinical suc-cess rate of TLE was 98.0%and proportion of no complications occurred was 95.4%.Fifteen patients(2.5%)had major complications,including 12 patients occured cardiac tamponade(9/12 atrial tears),and the rescue success rate was 83.3%(10/12).With the extension of lead retention,the complete success rate of extraction was reduced(P=0.00)and the major complication rate was increased(P=0.01).No effect of different device type,infection and non-infection indications on success and complications was observed.Conclusion Using NES to extraction leads is safe and effective.Cardiac tamponade is the most frequent cardiovascular complication.
