Brief Summary:
The purpose of this study is to demonstrate that QuickOpt optimization can be as an alternative method for CRTP/D patients' optimization in clinical practice through the comparison of the improvement differences between the CRTP/D patients with different optimization at 12 months after implantation.The hypothesis is that the Heart Remolding parameter (LVESV) improvement of patients using QuickOpt parameters at 12 months after implant is not inferior (10%) to the patients by Echo optimization。

Condition or disease Intervention/treatment Phase
Heart Failure Device: Cardiac Resynchronization Therapy Device: Optimization using echocardiography Not Applicable

Detailed Description:

Clinical studies have demonstrated that the AVTI from QuickOptTM related significantly to the max aorta VTI (AVTI) by Echo, the concordance correlation coefficient (CCC) was so high from 0.96 to 0.99.

But up to now, there are no clinical trials to evaluate mid-long term clinical outcome for CRTP/D patients by QuickOptTM and Echo optimization, this is indeed the main purpose of the study; in addition, the clinical impact, the status of arrhythmia and agents of all the enrolled patients, will be evaluated at 1 year after implant.

Arm Intervention/treatment
Experimental: Quickopt Group
the QuickOpt Group patients will be optimized by QuickOpt(IEGM);
Device: Cardiac Resynchronization Therapy
Patients will be optimized using QuickOpt (IEGM) algorithm installed on the Merlin device programmer within 2 weeks and 3 and 6 months after device implantation.

Active Comparator: Echocardiography group
the Echo Group patients will be optimized by Echo.
Device: Optimization using echocardiography
Optimization of the AV/PV and VV delays using echocardiography

Primary Outcome Measures :
  1. LV End Systolic Volume (LVESV) [ Time Frame: 12 months ]
    • To compare LV End Systolic Volume (LVESV) derived by the QuickOptTM optimization method with that derived by the echocardiography optimization methods at 12 months after implantation

Secondary Outcome Measures :
  1. Clinical parameters (NHYA class, SAS and 6 MHWD [ Time Frame: 12 months ]
    • To compare Clinical parameters (NHYA class, SAS and 6 MHWD ) derived by the QuickOptTM optimization method with that derived by the echocardiography optimization methods at 12 months after implantation
