Outcome Measures

Primary Outcome Measures :
  1. Subjects Successfully Implanted With an Attain Family Left-heart Lead Using an Attain Family Delivery Catheter [ Time Frame: Implant ]
    Implant success was defined as final successful placement of the Attain Family left-heart lead in the coronary vein branches utilizing the Attain Family of delivery catheters.

  2. Subjects Without a Left-heart Lead and Delivery Catheter Related Complication [ Time Frame: Implant to 3 months ]
    A left-heart lead and delivery related complication was defined as a complication, an adverse event that resulted in death, any termination of significant device function or invasive intervention, that resulted from the presence of or performance (intended or otherwise) of the Medtronic left-heart lead or Attain Family of delivery catheters. All adverse events were adjudicated by an Adverse Event Advisory Committee (AEAC).
