Abstract 15646: Efficacy of Higher-Pulse Rate vs. Lower-Pulse Rate Excimer Laser Sheath in Lead Extraction
Introduction: In April 2012, a new laser sheath using higher-pulse rate (80Hz), Glidelight® has been approved by FDA. We evaluate the efficacy of Glidelight in lead extraction when compared with previous lower-pulse rate laser sheath (40Hz), SLS II®
Methods: In this single-center, retrospective cohort study, we evaluated patients who underwent lead extraction from December 2008 to May 2013. The patients who underwent lead removal without using laser sheath or with approaches other than subclavian were excluded. Primary endpoints included total laser time, number of pulse and complications. Data on clinical characteristics, lead type, indications and outcomes were prospectively collected and analyzed.
Results: A total of 427 patients were included in the study (72.6% male; age 67.9 ± 15.23 years). SLS II and Glidelight were used in 315 and 112 patients respectively. 821 leads were removed with 765 leads (93.2%) extracted using excimer laser. Lead age was 5.71 ± 4.96 years. Complete extraction was seen in all patients. Although there was no significant difference in major and minor complications between these 2 groups, using higher pulse laser sheath was associated with lower laser time and lower total number of laser pulses even after adjustment for number and type of lead and lead age.
Conclusion: Higher-pulse rate laser sheath appears to be more efficient for lead extraction when compared with lower-pulse rate laser sheath without increase in major or minor complication rates.
