Real Time 3-Dimensional Echocardiography for Left Ventricular Lead Site Selection to Reduce Cardiac Resynchronization Therapy Non-Responder Rates (ENVISION)
In Brief
A clinical study evaluating 3D echo-guided LV lead placement for Heart Failure. Completed, enrolled 78 participants across 1 site.
Detailed Summary
The purpose of this study is to demonstrate that cardiac resynchronization therapy (CRT) responder rate can be improved by 3-dimensional (3D) echo-guided left ventricular (LV) lead placement compared to traditional LV lead placement.

Interventions
3D echo-guided LV lead placementprocedure
Information about left ventricular mechanical dyssynchrony and the location of the site of latest mechanical activation based on RT3DE will be available to the physician from the core lab analysis. This location will be used as the target for optimal LV lead placement.
