Clinical Trial Summary

The purpose of the S-ICD Post Approval Study is to document long term safety and effectiveness outcomes associated with the implantation of the SQ-RX pulse generator and Q-TRAK electrode in a commercial clinical setting.

Description:

The S-ICD Post Approval Study is a non-randomized registry that will retrospectively enroll subjects who participated in the S-ICD Clinical Investigation (IDE G090013) and prospectively enroll new candidates for the S-ICD System. The target enrollment sample size is 1,616 subjects at up to 150 investigational sites to achieve 1,025 subjects in the analysis cohort at 60 months. - The primary safety endpoint of the study is the Type I (caused by the S-ICD System) Complication Free Rate at 60 months compared to a performance goal of 85%. - The primary effectiveness endpoint is the Overall Shock Effectiveness in Converting Spontaneous Discrete Episodes of ventricular tachycardia /ventricular fibrillation (VT/VF) through 60 months compared to a performance goal of 94%. - The secondary safety endpoint of the study is the Electrode-Related Complication Free Rate at 60 months compared to a performance goal of 92.5%. - The secondary effectiveness endpoint is First Shock Effectiveness in Converting Induced (Acute) and Spontaneous Discrete Episodes of VT/VF through 60 months compared to a performance goal of 84.0%. Additional objectives include characterization of long term safety and effectiveness in subjects of varied body habitus and in traditionally underrepresented populations. Subjects must meet the following criteria to be eligible for inclusion in the study: 1. Eligible for implantation with an S-ICD System, OR previously implanted with an S-ICD System in the S-ICD System Clinical Investigation (IDE G090013) 2. Willing and able to provide written informed consent or have informed consent provided by a legal representative Subjects who meet the following criteria must be excluded from the study: 1. Remaining life expectancy of less than 360 days Enrolled subjects will be followed at the implant procedure, pre-discharge and annual (±60 days) follow-up visits. Subjects are followed according to the standard of care at their participating investigational center. The primary and secondary safety and effectiveness endpoints will include a compilation of S-ICD IDE study and S-ICD PAS study subject data

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Number of Participants Free From Type I Complication	Type I complications are adverse events caused by a component of the S-ICD System (i.e. pulse generator, electrode, EIT or programmer) that results in permanent loss of device function, invasive intervention or death.	60 months (1800 days)
Primary	Overall Shock Effectiveness in Converting Spontaneous Discrete Episodes of VT/VF	Overall shock effectiveness refers to conversion of an episode following on any of the 5 shocks (maximum) that may be delivered during a single episode. Discrete episodes of VT/VF are those that are temporally independent (<3 within a 24 hour period), unlike storm episodes, which occur in clusters (=3 episodes within a 24 hour period). Episodes that spontaneously terminate will be excluded from this endpoint since the effectiveness of the shock cannot be evaluated in such circumstances.	60 months (1825 days)
Secondary	Number of Participants Free From Electrode-related Complications	The electrode related complications analyzed for this end-point include: complications occurring less than or equal to 30 days post implant that are attributable to structural electrode failure for electrode movement, electrode impendence out of range, electrode conductor fracture, deformation or breakage or insulation failure; OR occurring greater than 30 days post implant regardless of structural failure for electrode movement, electrode impendence out of range, electrode conductor fracture, deformation/breakage or insulation failure; OR occurring greater than 30 days post implant attributable to structural electrode failure for incomplete/improper header connection, in-subject damage to electrode, electrode revision to optimize therapy, electrode movement, infection, oversensing/undersensing. Additionally, a complication is an adverse event that results in permanent loss of device function, invasive intervention or death.	60 months (1800 days)
Secondary	First Shock Effectiveness in Converting Induced (Acute) and Spontaneous Discrete Episodes of VT/VF	The rate in first shock effectiveness in converting induced (acute) and spontaneous discrete episodes of VT/VF through 60 months (1825 days) is calculated as the number of successful first shock conversions divided by the total evaluable episodes Acute Tests included: S-ICD PAS Study: Acute tests include induced episodes during the initial implant hospitalization after enrollment. Inductions may have been done on different days, but all occurred before the patient was discharged after initial implant; IDE Study : Acute tests included induced episodes occurring during the initial implant procedure as well as subsequent hospitalization until the final system position was obtained.; Acute Test Shock Energy Levels included all energy levels in the PAS Study and only 65 Joule shocks in the IDE Study.; Acute Test Arrhythmias included all VT and VF episodes for the PAS Study and only VF episodes for the IDE Study.	60 months (1825 days)
