Clinical Impact of Cardiac Resynchronization Therapy on Heart Failure Patients With QuickOpt and Echo Optimization

Abbott Medical Devices·interventional·Posted Jul 29, 2010·Updated Oct 8, 2019

In Brief

A clinical study evaluating Cardiac Resynchronization Therapy and Optimization using echocardiography for Heart Failure. Completed, enrolled 400 participants across 1 site.

Detailed 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。
