Safety and effectiveness will be summarized for the model 4965 lead. This study was conducted within Medtronic's System Longevity Study (SLS).

Heart Failure Pacing Bradycardia Arrhythmia

Study Type: Observational
Study Design: Observational Model: Cohort
Official Title: Medtronic Model 4965 Capsure Epi® Steroid-eluting Unipolar Epicardial Pacing Lead Post Approval Study

Further study details as provided by Medtronic Cardiac Rhythm and Heart Failure:

Primary Outcome Measures:
  • Model 4965 Complication Free Rate [ Time Frame: 1 year ]
    A 4965 lead-related complication is an adverse event requiring invasive intervention to resolve. The complication-free rate is based on the number of leads analyzed.

Enrollment: 73
Study Start Date: September 1996
Study Completion Date: April 2011
Primary Completion Date: April 2011 (Final data collection date for primary outcome measure)
Detailed Description:
As part of the requirement to satisfy the PMA Conditions of Approval for the Medtronic Model 4965 CapSure Epi® Steroid-Eluting Unipolar Epicardial Pacing Lead, 50 adult subjects who were ≥19 years old at time of implant were followed for one-year post-implant.

Ages Eligible for Study:   19 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population
Subjects 19 years or older implanted with Model 4965 Capsure Epi Lead.

Inclusion Criteria:

  • Subjects or appropriate legal guardians provide written informed consent and/or authorization for access to and use of health information, as required by an institution's IRB/MEC/REB

AND one of the following (A, B, or C) must also apply:

A. Subjects indicated for implant or within six months post-implant of a Medtronic market-released lead connected to a market-released IPG, ICD, or CRT Device. The Medtronic lead must be used for a pacing, sensing, or defibrillation application.

B. Subjects who participated in a qualifying study of a Medtronic cardiac therapy product and for whom:

  • product is market-released
  • complete implant and follow-up data, including product-related adverse events, are available
  • subject or appropriate legal guardian authorizes release of subject study data to SLS C. Subjects implanted with Medtronic CapSure Epi Leads (model 4965 and 4968) at a minimum of three pre-selected sites to retrospectively collect data for post approval requirements. Post approval requirements indicate 50 adult subjects implanted with a model 4965 and 100 subjects (pediatric and adult) implanted with a model 4968. The study plans to enroll approximately 100 subjects with a model 4965 lead and approximately 200 subjects with a model 4968 lead.

Note: Subjects currently active in the Chronic Lead Study or Tachyarrhythmia Chronic Systems Study will continue in the follow-up phase of the SLS.

Exclusion Criteria:

  • Subjects receiving an implant of a Medtronic lead at a non-participating center and the implant data and current status cannot be confirmed within 30 days after implant
  • Subjects who are, or will be inaccessible for follow-up at a SLS center
  • Subjects implanted with a Medtronic cardiac therapy device whose predetermined enrollment limit for that specific product has been exceeded
  • Subjects with exclusion criteria required by local law (EMEA only)
