AVEIR DR Dual Chamber Leadless Pacemaker System MRI Guide - Step-by-Step Instructions for Assessment and Programming

Oct 23, 2026

Uploaded by Sarah

AVEIR DR dual chamber leadless pacemaker system MRI guide provides step-by-step instructions for cardiac clinicians and physicians and for radiology/MRI technologists to support safe MR scanning. It defines pre-MRI assessment requirements, including confirmation of an MR Conditional system and screening for adverse conditions. It instructs clinicians to review potential adverse events, generate a report of permanently programmed parameters outside the scanner room, and select and save MRI settings such as MRI Mode, MRI Base Rate, and MRI Paced AV Delay.

PROCEED TO STEP 1 > AVEIR ™ DR DUAL CHAMBER LEAD LESS PACEMAKER SYSTEM MRI GUIDE ROLES OF THE CARDIAC PHYSICIANS AND CLINICIANS STEP 1 CONFIRM THAT THE PATIENT HAS AN MR CONDITIONAL SYSTEM Review the patient’s ID card or a printed report generated by the Merlin™ Patient Care System (PCS) Programmer to obtain the model number for the implanted device(s) . Check that each model number is MR Conditional. | MR Conditional Models for the AVEIR™ Leadless Pacemaker System | | --- | | LSP112V | | LSP202V | | LSP201A | | LSP203A | AVEIR ™ Single Chamber Leadless Pacemakers and Dual Chamber Leadless Pacemaker System are MR Conditional Patient ID card with model number highlighted. IF CONFIRMED, PROCEED TO STEP 2 > AVEIR ™ DR DUAL CHAMBER LEAD LESS PACEMAKER SYSTEM MRI GUIDE ROLES OF THE CARDIAC PHYSICIANS AND CLINICIANS STEP 2 CONFIRM THAT NO ADVERSE CONDITIONS TO MRI SCANNING ARE PRESENT EXAMPLES OF ADVERSE CONDITIONS: • A device is at End-of-Service • An implanted LSP112V or LSP202V is implanted at a site other than the right ventricle • An implanted LSP201A or LSP203A is implanted at a site other than the right atrium • A device has unstable capture thresholds OR has a threshold greater than 2.5V@0.5ms • Complaints of diaphragmatic stimulation when outputs are set to 5.0V@1.0ms, if the patient will be paced when MRI Settings are enabled • Patients with other non-MR Conditional implants (eg. abandoned leads) SEE NEXT PAGE FOR FURTHER CLARIFICATION RELATED TO ADDITIONAL IMPLANTED DEVICES OR ABANDONED LEADLESS PACEMAKERS. AVEIR ™ DR DUAL CHAMBER LEAD LESS PACEMAKER SYSTEM MRI GUIDE ROLES OF THE CARDIAC PHYSICIANS AND CLINICIANS ADDITIONAL NOTES FOR CLARIFICATION IT IS ACCEPTABLE TO SCAN PATIENTS WITH OTHER MR CONDITIONAL IMPLANTABLE DEVICES PROVIDED ALL MR CONDITIONAL REQUIREMENTS FOR EACH IMPLANTED DEVICE ARE MET. IT IS ACCEPTABLE TO SCAN PATIENTS WITH OTHER ABANDONED MR CONDITIONAL LEADLESS PACEMAKERS IN THE SAME CHAMBER, AS LONG AS: 1. MR conditions for each leadless pacemaker are met 2. Abandoned leadless pacemakers are deactivated IF ANY CONDITIONS EXIST WHICH COULD MAKE MRI SCANNING UNSAFE, IF NO ADVERSE CONDITIONS PRESENT, PROCEED TO STEP 3 > DO NOT SCAN THE PATIENT.

FAQs

How should clinicians confirm the patient has an MR Conditional system before MRI scanning?

Review the patient’s ID card or generate a report with the Merlin PCS Programmer to obtain device model numbers, then verify each model number is MR Conditional (e.g., LSP112V, LSP202V, LSP201A, LSP203A).

What adverse conditions mean the patient should not be scanned?

Examples include devices at end-of-service, implanted leadless pacemakers positioned outside the specified chamber sites, unstable capture thresholds or thresholds greater than 2.5V@0.5ms, diaphragmatic stimulation concerns under specified outputs when pacing will be enabled, or other non-MR Conditional implants such as abandoned leads.

What are the main MRI settings that can be selected and saved?

Under Parameters > MRI Settings, clinicians can change MRI Mode, MRI Base Rate, and MRI Paced AV Delay (with provided nominal values and options for each).
