Why the study?
What are the real-world service times of different ICD systems and do they vary by device type, settings, or manufacturer?

Single-chamber ICDs and specific manufacturers (Medtronic) demonstrate significantly longer real-world generator longevity compared to dual-chamber/CRT-D systems and other brands.

May inform device selection for longevity; extends observational data but leaves practice change open pending trials.
Knops et al. (2009) studied this question.
