Boston Scientific Post Market Subcutaneous-Implantable Cardioverter Defibrillator (S-ICD) Registry

Completed
Conditions
Tachycardia, Ventricular
Interventions
Device: S-ICD System
Registration Number
NCT01085435
Lead Sponsor
Boston Scientific Corporation
Brief Summary

The EFFORTLESS ICD Registry is an observational, standard of care evaluation designed to demonstrate the early, mid and long-term clinical effectiveness the Boston Scientific S-ICD System. In addition, analysis of resource utilization and costs will be performed to document treatment costs for periods defined by Registry endpoints. Protocol 90904928 restricts enrolment to patients over 18 years of age while protocol 90904925 allows all patients to be included.

Detailed Description

EFFORTLESS is an observational, post market, standard of care, Registry to be conducted at approximately 50 centers worldwide in patients requiring an ICD for the treatment of ventricular tachyarrhythmias. Patients included in the registry will have been implanted with the S-ICD system since its CE mark (commercial regulatory approval) and will be followed for up to 60 months. The patients' perception of their therapy will be evaluated using Quality of Life assessments and the Registry will include an exploratory analysis of resource utilization and costs based on measures of clinical outcome such as complication rates, unscheduled hospitalizations and length of stay. The objective will be to enable comparison of costs of the S-ICD system versus a standard transvenous system.

An Extension Phase Sub-Study will extend the EFFORTLESS S-ICD Registry in order to achieve an average of approximately 8 years of follow-up from index procedure. A subgroup of approximately 200 patients will be enrolled at a sub-set of EFFORTLESS sites. The data analysis will focus on long-term S-ICD system-related adverse events, S-ICD replacements and device longevity.

  3. Willing and able to provide written informed consent or have informed consent as provided by a legal representative and willing to participate in all testing and follow-ups as described the Sub-Study protocol
  4. Age 18 or above, and of legal age to give informed consent specific to national laws

Exclusion Criteria

  1. Subjects with device replacement from the S-ICD to a transvenous ICD
  2. Subjects with unipolar pacemakers or implanted devices that revert to unipolar pacing
  3. Subjects that are participating in any other investigational study that may interfere with interpretation of the Registry results, without the written approval of Boston Scientific

Extension Phase Sub StudyS-ICD SystemThe Sub-Study patients were preferably recruited from the active EFFORTLESS S-ICD patient population. Patients, who had already completed the EFFORTLESS S-ICD Registry in the past, were considered secondarily for participation in the Sub-Study.
EFFORTLESS Main StudyS-ICD SystemPatients implanted with a CE marked S-ICD System, not participating in Cameron Health's Investigational Device Exemption (IDE) Clinical Study.
