Assurity MRI™

Single chamber and Dual chamber Pacemaker


Clinical Evidence

In addition to allowing for full-body 1.5T and 3T MRI scans,* the Assurity MRI pacemaker provides other clinical benefits.

Minimize Risk of Heart Failure Hospitalization

Unnecessary right ventricular (RV) pacing can exacerbate heart conditions:

  • Pacing > 40% can lead to increased heart failure (HF) hospitalizations and mortality1
  • Patients with low RV pacing (0-9%) have the same negative outcomes as those with high RV pacing (40-49%)2

The Abbott Ventricular Intrinsic Preference (VIP™) algorithm with dynamic AV delay is clinically proven to reduce unnecessary RV pacing.3 The VIP algorithm is shown to reduce heart-failure-related hospitalization3, and offers RV pacing at desirable levels (10-19%).3

Early Insight

The Assurity MRI pacemaker works together with a wireless remote monitoring system. Remote monitoring capabilities provide earlier notification of actionable clinical events, allowing you to detect patient status changes sooner.

  • The ASSERT clinical trial has shown that subclinical atrial tachyarrhythmias (AT) are associated with a 2.5-fold increased risk of stroke or systemic embolism.4
  • Remote monitoring has been shown to reduce mortality in pacemaker patients.5
  • The Assurity MRI pacemaker can help you identify patients at risk for stroke earlier, with clinically proven AT/atrial fibrillation (AF) diagnostic tools.4
  • The Abbott remote follow-up system,™ Patient Care Network (PCN), reduces clinician6,7 and patient follow-up costs.7
  • Wireless, radio-frequency telemetry offers faster access to clinical data, increasing the possibility for clinical efficiency at implant and follow-up.8
