The objective of this study is to demonstrate that frequent paced/sensed AV and V-V delay optimization using QuickOpt in patients with CRT-D device results in improved clinical response and structural remodeling over standard care (i.e. empiric programming or one-time optimization using any non-IEGM optimization methods).
Efficacy
Exploratory
Pragmatic
Not applicable
A combination of symptomatic improvement (>=1 class reduction in specific activity scale (SAS) or >= 25% improvement in 6 minute walk test distance) and LV remodeling (>= 15% reduction LV end systolic volume or >= 5% improvement in LVEF)
1) Rate of late (12-month) response to CRT
2) Changes in B-type natriuretic peptide (BNP) in correlation to cardiac remodeling
3) Inter- / intra-ventricular dyssynchrony compared to usual optimization

The paced / sensed AV and V-V delays will be optimized using QuickOpt. Optimization will be performed at enrollment, 3 month, 6 month, 9 month, 12 month and at any unscheduled follow-up visits.
The paced / sensed AV and V-V delays could be programmed empirically or optimized using any non-IEGM based method as per sites standard of care. Patients can be optimized only once within the first 4 weeks post implant.
