PRIMARY outcome

Timeframe: 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.

Outcome measures

Outcome measures
Measure
Attain Family Lead and Catheter Attempt
n=1917 Participants
Subjects who were attempted with an Attain Family left-heart lead after successful coronary sinus (CS) cannulation with an Attain Family catheter were included in this analysis as well as subjects who had unsuccessful CS cannulation with an Attain Family delivery catheter.
Subjects Successfully Implanted With an Attain Family Left-heart Lead Using an Attain Family Delivery Catheter
1802 participants
Interval 0.929 to 0.95

PRIMARY outcome

Timeframe: 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).
