Real Time 3-Dimensional Echocardiography for Left Ventricular Lead Site Selection to Reduce Cardiac Resynchronization Therapy Non-Responder Rates

Real Time 3-Dimensional Echocardiography for Left Ventricular Lead Site Selection to Reduce Cardiac Resynchronization Therapy Non-Responder Rates (ENVISION)

• Status: Completed
• Phase: N/A
• Study type: Interventional
• Enrollment: 78 (actual)
• Sponsor: Abbott Medical Devices · Industry
• Sex: All
• Age: —
• Healthy volunteers: Not accepted

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.

Conditions

• Heart Failure

Interventions

Type	Name	Description
PROCEDURE	3D echo-guided LV lead placement	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.
