Quadripolar Pacing Post Approval Study (Quad PAS)

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT01555619
Recruitment Status : Completed
First Posted : March 15, 2012
Last Update Posted : April 16, 2019

Abbott Medical Devices

Brief Summary:
The purpose of this post-approval study is to evaluate the acute and chronic performance of a Quadripolar CRT-D device system in a patient population indicated for cardiac resynchronization therapy (CRT).

Condition or disease Intervention/treatment
Heart Failure Device: CRT-D System

Detailed Description:
Quad PAS is a multi-center, post-approval study. Patients who meet inclusion/exclusion criteria will have an attempted implant of a Quadripolar CRT-D device system (device and left ventricular (LV) lead). Patients who have an unsuccessful implant will be followed for 30 days for any adverse events and then withdrawn from the study, or may have an implant reattempted if the physician chooses to do so. Patients enrolled in the study will be followed at 6 months, and every 6 months thereafter, for 60 months of follow up (5 years). After patients complete 60 months of follow-up, their participation in the study will be terminated.
