Study Description
Brief Summary:
The purpose of this study is to demonstrate that epicardial and transvenous left ventricular leads are safe and effective for cardiac resynchronization therapy in heart failure patients implanted with a CRT device.

Condition or disease Intervention/treatment
Heart Failure Device: Cardiac Resynchronization Therapy implant

Detailed Description:

This clinical trial is a multicenter, prospective, randomized, parallel, open study designed to compare epicardial left ventricular pacing to transvenous left ventricular pacing for delivering cardiac resynchronization therapy.

After a pre-implant baseline evaluation, patients will be randomized in a 1:1 fashion to one of two groups:

  • Control group: resynchronization via a transvenous left ventricular lead (TVN CRT);
  • Treatment group: resynchronization via an epicardial left ventricular lead (EPI CRT).

All patients taking part in this study will undergo the implantation of a CRT device with or without ICD back-up (depending on the physician's decision), with right atrial and right ventricular transvenous leads.

Patients will attend protocol scheduled visits before implant (pre-implant baseline evaluation), and post-implant: before hospital discharge, 6 weeks post-implant (optional visit), 3 months (optional visit), and 6 months after implant, time of study termination.

Arms and Interventions

Arm Intervention/treatment
Active Comparator: Transvenous Lead (TVN CRT)
Control group: resynchronization via a transvenous left ventricular lead (TVN CRT)
Device: Cardiac Resynchronization Therapy implant
Device implant with appropriate leads
Experimental: Epicardial Lead (EPI CRT)
Treatment group: resynchronization via an epicardial left ventricular lead (EPI CRT)
Device: Cardiac Resynchronization Therapy implant
Device implant with appropriate leads


Outcome Measures

Primary Outcome Measures :
  1. The efficacy will be evaluated by comparing the pacing thresholds at 6 months between the two groups. The safety will be evaluated by comparing the survival from lead-related complications at 6 months between the two groups. [ Time Frame: 6 months follow up after implant ]
