BackgroundGiven the exponential growth in cardiac device implantations, the need for less invasive lead extraction is increasing. The Excimer laser was approved for lead removal in Japan in 2010. The present study reports the initial experience using this novel technique to extract chronically implanted pacemaker and implantable cardioverter defibrillator (ICD) leads from Japanese patients.Methods And ResultsWe performed a retrospective study of consecutive patients undergoing lead extraction using the laser sheath at a single Japanese center. Patient and lead characteristics, indications, and outcomes were analyzed. From August 2010 to September 2012, a total of 70 leads, including 14 ICD leads, were removed using the laser sheath from 40 patients (26 male, 14 female; age 65.5±18.3 [mean±SD] years; body mass index 21.8±3.5 kg/m2). The median implant duration was 87 months (range 13-328 months). Indications were infection (n=35), venous occlusion (n=4), and pain (n=1). The femoral approach was used in combination with the laser technique in five cases. Complete procedural success was achieved with 68 leads (97.1%). Although the electrode tip was left behind in the remaining two leads, the desired clinical outcomes could be achieved; which were defined as clinical success. No cases resulted in failure. There were no major complications, including death and bleeding requiring open-chest surgery.ConclusionsLaser sheaths appear to provide a feasible and effective means of extracting chronically implanted pacemaker and ICD leads in Japanese patients.Copyright © 2013 Japanese College of Cardiology.
