Purpose
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 CRT-D device results in improved clinical response over standard of care (i.e. empiric programming or one-time optimization using any non-IEGM optimization methods).

Primary Outcome Measures:
- Heart Failure clinical composite score
Secondary Outcome Measures:
- All-cause, cardiovascular and heart failure mortality; All-cause, cardiovascular and heart failure hospitalizations
- Additional Data : 6 minute hall walk; Quality-of-life (QOL) score; Changes in AV/PV and VV delays; Time required for optimization; Frequency of atrial and ventricular arrhythmias; Percent atrial and ventricular pacing
| Estimated Enrollment: | 1500 |
| Study Start Date: | October 2006 |
- 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 BiV 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 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.
