Primary Outcome Measures:
  • Model 4296 LV Lead-related complication rate [ Time Frame: 5 years ]
    To demonstrate that the Model 4296 lead-related complication-free probability

Secondary Outcome Measures:
  • Types of lead-related adverse device effects [ Time Frame: 5 years ]
    To summarize all lead related adverse events

  • Percent of subjects with changes in electrode programming [ Time Frame: 5 years ]
    To characterize any changes in electrical programming

  • Number of fractures with and without loss of function [ Time Frame: 5 years ]
    To characterize fractures with and without loss of function

  • Bipolar electrical performance at 1 year [ Time Frame: 1 year ]
    To summarize bipolar electrical performance at one year post implant

  • Bipolar pacing impedance [ Time Frame: 1 year ]
    To characterize threshold measurements and impedance for both conductors

  • Bipolar pacing capture threshold [ Time Frame: 1 year ]
    To characterize standard bipolar pacing voltage thresholds

Detailed Description:
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 conducted within Medtronic's post-market surveillance platform.
