The FDA has the authority to require sponsors to perform a post-approval study (or studies) at the time of approval of a premarket approval (PMA), humanitarian device exemption (HDE), or product development protocol (PDP) application. Post-approval studies can provide patients, health care professionals, the device industry, the FDA and other stakeholders information on the continued safety and effectiveness (or continued probable benefit, in the case of an HDE) of approved medical devices. This database allows you to search Post-Approval Study information by applicant or device information.

Comparison Group Objective Performance Criterion
Analysis Type Analytical
Study Population Transit. Adolescent B (as adults) : 18-21 yrs, Adult: >21
Detailed Study Protocol Parameters
Study Design Description This study utilizes the Medtronic¿s Post-Approval Network Product

Surveillance Registry (PSR) designed to conduct non-randomized, active prospective post-market Surveillance. The Registry is sponsored by Medtronic and is comprised of a global network of hospitals, clinics and clinicians from which reliable ¿real world¿ product safety and patient clinical outcome information is generated.

Study Population Description The study will consist of patients rolled over from the pre-market study and patients newly enrolled in the postapproval study all tracked within the System Longevity Study sponsor registry. These are patients indicated for chronicpacing and sensing in the left ventricle via thecardiac vein, when used in conjunction with a compatible Medtronic Cardiac Resynchronization Therapy system.
Sample Size 1778 patients, 60 sites
Data Collection The endpoints include the complication free rate will be estimated based on the chronic (> 30 days post implant) clinical adverse events including 1) failure to capture, 2) failure to sense, 3) Undersensing, 4) Threshold rise, 5) Oversensing, 6) Abnormal pacing impedance, 7) Lead insulation breach, 8) Lead conductor fracture, 9) Extracardiac stimulation, 10) Cardiac perforation, 11) Lead dislodgement, and 12) Structural Lead Failure.
Follow-up Visits and Length of Follow-up Patients will be followed every six months for 5 years
Final Study Results
Interim Safety Information There were 3 (in 3 leads) Model 4196 related observations, no Model 4196 related complication, and no deaths reported.
