Lead Safety
Safety of the Tendril MRI
™
lead was evaluated in terms of freedom from RA and RV lead-related
complications for the acute (implant to two-month visit) and chronic (two-month visit through the
12 month visit) time frames.
MRI Safety
The safety of the Accent MRI system was evaluated in terms of freedom from MRI scan-related
complications in the month following the MRI scan.
Lead Efficacy
Efficacy of the Tendril MRI
™
lead in was evaluated in terms of the change in bipolar atrial and
ventricular capture and sensing thresholds before and after the MRI scan.
Secondary Objectives
The secondary objectives are listed below.
Safety
Safety of the Accent MRI
™
system was evaluated in terms of freedom from system-related
complications through the 12 month visit.
Efficacy
Efficacy of the Tendril MRI
™
lead was evaluated in terms of the bipolar atrial and ventricular
capture thresholds at the MRI Visit.
