314 medical device reports received by FDA name the brand "Marquis Vr" (implantable pacemaker/cardio/defib); the manufacturer given most often on reports is Medtronic Med Rel; received from May 2003 to July 2019. Brand names are as the reporter or manufacturer wrote them, so one product can appear under several spellings.

0 reports arrived in the 12 months to August 2026, and none in the 12 months before. FDA releases MAUDE data monthly; reports can arrive months after an event, so the newest months grow in later releases. The event types recorded are injury (73.2%), malfunction (21.7%) and death (4.8%); across all implantable cardioverter defibrillator (non-crt) reports (product code LWS) death is recorded in 2.7% and malfunction in 37.4%. Event type is the reporter's classification of the report, not a verified outcome.

The device problems coded most often are reset problem (12.4%), inappropriate/inadequate shock/stimulation (9.9%) and premature discharge of battery (8%). The patient problems coded most often are shock from patient lead(s), ventricular tachycardia and death. FDA states that "MDR data alone cannot be used to establish rates of events, evaluate a change in event rates over time or compare event rates between devices. The number of reports cannot be interpreted or used in isolation to reach conclusions about the existence, severity, or frequency of problems associated with devices." It adds that the reporting system "has limitations, including the potential submission of incomplete, inaccurate, untimely, unverified, or biased data."
