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.

Time Frame |
|---|---|---|

Percent Change in Left Ventricular End Systolic Volume (LVESV) at 12 Months Compared to Baseline
Time Frame: Baseline and12 months
|
The primary outcome is the percent change in LVESV at 12 months compared to baseline.
This outcome measure is assessed through evaluation of echocardiograms at both baseline and 12 months, with a decrease in the percent change in LVESV at 12 months indicating clinical improvement.
The percent change in patients with devices optimized with QuickOpt is compared with that of patients with devices optimized using standard echocardiography techniques to determine if one method of optimization results in a greater change in LVESV.
