Key result
Active surveillance of over 370,000 ICD leads using the NCDR registry found no difference in lead survival rates between matched groups, with failure-free survival ranging from 97.7% to 98.9%.

Active surveillance of clinical registries using novel algorithms offers a promising, though imperfect, paradigm for postmarket monitoring of ICD lead survival.
Zeitler et al. (2020) conducted an editorial in Implantable cardioverter-defibrillator (ICD) implantation (n=370,000). Specific ICD lead models vs. Propensity-matched comparator group receiving all other lead models was evaluated on Lead failure (using lead replacement as a surrogate). Active surveillance of over 370,000 ICD leads using the NCDR registry found no difference in lead survival rates between matched groups, with failure-free survival ranging from 97.7% to 98.9%.
