Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Control group

Patients will be implanted according to the standard of care with the LV lead in the traditional LV lead position.

Group Type NO_INTERVENTION

No interventions assigned to this group

3D echo-guided LV lead placement group

Information about left ventricular mechanical dyssynchrony and the location of the site of latest mechanical activation based on Real-Time 3-Dimensional Echocardiography (RT3DE) will be available to the physician at the time of implant. This location will be used as the target for optimal LV lead placement.

Group Type EXPERIMENTAL

3D echo-guided LV lead placement

Intervention Type PROCEDURE

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.
