Poli S, et al. - Researchers examined the service life of implantable cardioverter-defibrillators (ICDs) over a 10-year interval. In addition, they sought for the main causes of replacement on the basis of data from the National ICD Registry of the Italian Society of Arrhythmology and Cardiac Pacing (AIAC). Inclusion of 29,158 records from 27,676 patients was done (80.9% men; mean age at device replacement 65.8±12.0 years). Analysis revealed the median service life of 57.3 months (interquartile range 27.8 months) with an increasing trend over the years. Elective replacement was done in the majority of patients due to battery end of life, and over the years, a significant reduction of replacement for recalls, erosion/infections, and cardiac resynchronization therapy upgrading, was reported.
