Evolución temporal en la implantación de electrodos de desfibrilación monobobina o bibobina en nuestro país. Datos de un gran registro español

Abstract

Introduction and objectivesThere is no data available on the use of implantable defibrillator leads in Spain. Dual-coil defibrillator lead has been the most common lead system in clinical practice in the last twenty years. The aim of this study is to give an idea about how defibrillator leads have been implanted in Spain over a 10-year period. A Secondary objective consists on trying to identify differences between both type of leads. MethodsWe have analysed data from 4131 Spanish patients that carry an implantable cardioverter-defibrillator, that were included in the UMBRELLA trial and followed remotely with CareLink system between 2005 and 2016. ResultsInitially, the proportion of single-coil defibrillation leads was less than 10%. After 2014, the proportion of single-coil leads has increased, being the most frequent type of lead in the year 2016 (51.8% vs 48.2%). We have not appreciated differences between both defibrillation leads beyond a higher incidence of administered shocks in dual-coil leads (17.5% vs 5.8%; p<.001). This observation is probably related to the way on defibrillators were programed some year ago. ConclusionsDuring the last years, clinical practice with defibrillators has changed in the way devices are implanted and programed. When we analysed defibrillation lead data in our study, we observed a change in the choice of the lead type, being single-coil leads the most commonly implanted in recent years.
