The objective of this study is to demonstrate that frequent atrio-ventricular (AV/PV) and inter-ventricular (V-V) delay optimization using QuickOpt in patients with cardiac resynchronization therapy device results in improved clinical response over standard of care (i.e. empiric programming or one-time optimization using any non-intracardiac electrogram optimization methods).

Primary Outcome Measures:
  • Heart Failure Clinical Composite Score [ Time Frame: 12 months ]
    The clinical composite score classifies each randomized patient as improved, unchanged, or worse depending on the clinical response during and the clinical status at the end of the trial. Patients are considered improved if at the final visit they experienced a favorable change in NYHA functional class or in the patient global assessment (or both) but did not experience any major adverse clinical events during the course of the trial. Patients are considered worse if they experienced a major clinical event during the study duration or reported worsening of their NYHA class or global assessment at the final visit. Patients are considered unchanged if they are neither improved nor worse.

Secondary Outcome Measures:
  • All-cause, Cardiovascular and Heart Failure Mortality; [ Time Frame: 12 months ]
  • All Cause, Cardiovascular and Heart Failure Hospitalization [ Time Frame: 12 months ]

Enrollment: 1647
Study Start Date: October 2006
Study Completion Date: September 2009
Primary Completion Date: September 2009 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: QuickOpt (Treatment)
Frequent optimization using QuickOpt to optimize the AV/PV and VV Delays.
Device: QuickOpt
Frequent optimization using QuickOpt to optimize AV/PV and VV delays.
Active Comparator: Control
Empiric programming or one-time optimization using a non-IEGM method.
Device: Control
Empiric programming or one-time optimization using a non-IEGM method.

Detailed Description:
  • This is a prospective, double-blinded, multicenter, randomized study
  • Patient could be enrolled up to 2 weeks post CRT-D implant and are followed for 12 months post implant with follow-up visits at 3, 6, 9 and 12 months
  • Patients will be randomized at enrollment to either Group 1 ("QuickOpt Group") or Group 2 ("Control Group").
  • Group 1 - The patient's device is programmed to sequential biventricular pacing mode with AV/PV and VV delays optimized using QuickOpt. For Group 1 patients, optimization using QuickOpt is performed at enrollment, 3 month, 6 month, 9 month, 12 month and at any unscheduled follow-up visits.
  • Group 2 - The patient's device is programmed to either simultaneous or sequential BiV pacing mode as per physician's discretion. The AV/PV and inter-ventricular (VV) delays could be programmed empirically or optimized using any non-IEGM based method as per sites standard of care. However, the Group 2 patients can be optimized only once within the first 4 weeks post implant. Any AV/PV and VV delay optimizations performed after 4 weeks post implant in Group 2 patients will be considered protocol deviations.
