The purpose of this study is to evaluate long-term performance of the 4296 LV Lead. This evaluation is based on the number of lead-related complications occurring during the study compared to the number of leads enrolled in the study. The leads will be followed for 5 years after implant. This study is required by FDA as a condition of approval of the Model 4296 LV Lead. This study is part of the Product Performance Platform (PPP).

Sampling Method:   Non-Probability Sample
Study Population

Patients implanted with a 4296 LV Lead within 30 days. All subjects must meet Inclusion criteria and none of the Exclusion criteria.


Inclusion Criteria:

  • Subject or appropriate legal guardian provides written informed consent and authorization for access to and use of health information (if applicable).
  • Complete implant and follow-up data, including Model 4296 lead-related events are available.

AND one of the following must apply:

  • Subject is within 30 days post-implant of a 4296 Model lead connected to a market released Cardiac Resynchronization Therapy (Cardiac Resynchronization Therapy-Pacemaker or Cardiac Resynchronization Therapy-Defibrillator) device. The Medtronic lead must be used for a pacing or sensing application.
  • Subject who participated in the Medtronic Attain Ability Model 4296 Left Ventricular Lead Pre-Market Study.

Exclusion Criteria:

  • Subject implanted at a non-participating site, and implant, follow-up data, including Model 4296 lead-related events are not available within 30 days from implant.
  • Subject who is, or will be inaccessible for follow-up at a study site.
  • Subject with exclusion criteria required by local law (Europe, Middle East or Africa only).
