Primary Outcome Measures:
  • 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.

  • 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).

Study Population
Patient referral to a participating study center with practitioners experienced in handling and implantation of the cardiac resynchronization therapy (CRT) device, the left-heart lead, and the use of the delivery catheter.

Inclusion Criteria:

  • Subject is at least 18 years of age or older
  • Subject will be implanted with Medtronic cardiac resynchronization therapy (CRT) device and Medtronic left heart lead utilizing (or attempting to utilize) Attain Family of delivery catheters. The implant procedure may include upgrades to CRT from implantable pulse generator (IPG) or implantable cardioverter-defibrillator (ICD).

Exclusion Criteria:

  • Subject is enrolled in a concurrent study with the exception of a study approved by the Medtronic Clinical Trial Leader prior to enrollment
  • Subject has existing CRT system implanted or was previously implanted with a CRT system.
