A new fastening system for temporary pacing with active-fixation leads: effectiveness and safety

Abstract

Aims: Temporary cardiac pacing with active-fixation leads (TPAFL) using a reusable permanent pacemaker generator has been shown to be safer than lead systems without fixation. However, TPAFL requires the off-label use of pacemaker leads and generators. We designed a fastening system to ensure the safety and efficacy of the procedure: the KronoSafe System®. To demonstrate the safety and effectiveness of the KronoSafe System® for temporary pacing in a series of patients receiving TPAFL. Methods and results: A prospective cohort of 20 patients undergoing TPAFL between August 2019 and June 2020 was recruited in a Spanish region. The temporary pacemaker was implanted through jugular access and secured with the KronoSafe System®. R-wave detection, lead impedance, and capture threshold were assessed every 48 h. Complications associated with the procedure or occurring during TPAFL were recorded. There were no complications associated with temporary pacing, and the therapy was effective in all cases. TPAFL was used for a mean of 7.6 days (maximum 25 days), and 84.56% of the time in a cardiology ward. Conclusion: TPAFL secured using the KronoSafe system® provides safe and stable cardiac stimulation for patients requiring temporary cardiac pacing.
