Official Title: Electronic Repositioning With Acuity and Easytrak Leads

Further study details as provided by Boston Scientific Corporation:

Primary Outcome Measures:
  • LVP thresholds and PNS, LVP thresholds in all 4 ER configurations, incidence of high LVP thresholds and PNS, Frequency of use of ER due to high LVP, Handling and stability of anatomic LV lead position, time LV-lead placement and X-ray exposure [ Time Frame: From implant until 6 month follow-up ]

Enrollment: 400
Study Start Date: September 2006
Study Completion Date: September 2009
Primary Completion Date: March 2009 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
LV lead electronically repositioning
Single arm study
Device: Electronic Repositioning
Change of pacing vectors for CRT pacing

Detailed Description:
"Bipolar leads for left ventricular pacing (LVP) such as the newly available ACUITY TM or the standard EASYTRAK TM II and EASYTRAK TM III leads from GUIDANT in combination with suitable devices for cardiac resynchronisation therapy (CRT) allow for the non-invasive programming of different LVP configurations. Hence, this Electronic RepositioningTM (ER) may help physicians to overcome problems in CRT such as ineffective biventricular pacing, high LVP thresholds and phrenic nerve stimulation (PNS) without the need for an additional patient's operation to reposition LV leads.The ERACE study it a multi-centre, prospective, non-randomized clinical study to document and evaluate appropriate performance of GUIDANT's Electronic Repositioning™ in the clinical routine with respect to the following major aspects: avoidance of PNS and low LVP thresholds (for low battery consumption and extended device longevity) in standard cardiale resynchronisations therapy (CRT). "
