Subcutaneous ICD (S-ICD) Trials and Studies

2-year Results from a Pooled Analysis of the IDE Study and EFFORTLESS Registry

Combining these two studies provides a unique opportunity to evaluate complications as well as amass a significant number of spontaneous events in 882 implanted patients followed for 1,517 patient-years.


The EFFORTLESS S-ICD Registry is a non-randomized, standard of care, multicenter registry designed to collect long term system-related, clinical, and patient reported outcome data from S-ICD implanted patients since June 2009.
