ProMRI AFFIRM Study of the EVIA/ENTOVIS Pacemaker With Safio S Pacemaker Leads (ProMRIAFFIRM)

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT01460992
Recruitment Status : Completed
First Posted : October 27, 2011
Last Update Posted : November 28, 2013

Brief Summary:
This investigation is designed to demonstrate the clinical safety of the EVIA/ ENTOVIS pacemaker system when used under specific MRI conditions.

Condition or disease Intervention/treatment
Cardiac Disease Procedure: Evia/Entovis pacemaker system under Magnetic Resonance Imaging (MRI) conditions

Detailed Description:

In the past, MR scans were always contraindicated for pacemaker patients. If particular prerequisites and conditions are fulfilled, MR scans can now be conducted on patients with BIOTRONIK's EVIA/ENTOVIS pacemakers in combination with the Safio S pacemaker leads, scheduled to be part of this clinical study.

The specific MRI conditions for this investigation with the EVIA/ENTOVIS pacemaker family and Safio S pacemaker leads are defined in the study protocol

Layout table for study information
Study Type : Observational
Actual Enrollment : 121 participants
Observational Model: Case-Only
Time Perspective: Prospective
Official Title: Master Study for the MRI Compatibility of the EVIA/ENTOVIS Pacemaker in Combination With Safio S Pacemaker Lead
Study Start Date : March 2012
Actual Primary Completion Date : October 2013
Actual Study Completion Date : November 2013

Group/Cohort Intervention/treatment
Pacemaker therapy
Patients with an EVIA/ ENTOVIS pacemaker device. See inclusion and exclusion criteria.
Procedure: Evia/Entovis pacemaker system under Magnetic Resonance Imaging (MRI) conditions
patients will undergo an MRI scan for 30 minutes.
Other Names:
  • Evia/Entovis SR-T (single chamber with telemetry function), DR-T (dual chamber with telemetry function)
  • Atrial/ventricular lead(s): Safio S 53 and S 60.
  • Safio S 45

Primary Outcome Measures :
  1. Primary hypothesis 1: MRI and pacing system related Serious Adverse Device Effect (SADE) free rate [ Time Frame: 3 months ]
    MRI and pacing system related Serious Adverse Device Effect (SADE) Free-Rate is greater than 90%.

  2. Primary hypotheses 2 and 3: pacing threshold rise (atrial and ventricular) [ Time Frame: 1 month ]
    The atrial or ventricular MRI induced pacing threshold rise is not larger than or equal to 0.5 V between Pre-MRI and 1-month follow-up

  3. Primary hypothesis 4: P-wave sensing attenuation [ Time Frame: 1 month ]
    P-wave attenuation: P-wave amplitude decrease (between pre-MRI follow-up and 1-month follow-up) exceeding 50% or a P-wave amplitude at 1-month follow-up smaller or equal to 1.5 mV

  4. Primary hypothesis 5: R-wave sensing attenuation [ Time Frame: 1 month ]
    R-wave attenuation: R-wave amplitude decrease (between pre-MRI follow-up and 1-month follow-up) exceeding 50% or a R-wave amplitude at 1-month follow-up smaller or equal to 5.0 mV.
