1,324 medical device reports received by FDA name the brand "Carpentier-Edwards Perimount Magna Aortic Bioprosthesis" (replacement heart valve); the manufacturer given most often on reports is Edwards Lifesciences; received from January 2005 to May 2026. Brand names are as the reporter or manufacturer wrote them, so one product can appear under several spellings.
11 reports arrived in the 12 months to August 2026, down 69% from 36 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 (69.9%), death (27.1%) and malfunction (1.8%); across all heart-valve, non-allograft tissue reports (product code LWR) death is recorded in 8% and malfunction in 4.9%. Event type is the reporter's classification of the report, not a verified outcome.
The device problems coded most often are insufficient device problem information (12.4%), gradient increase (9.8%) and explanted (7.6%). The patient problems coded most often are death, aortic valve stenosis and aortic regurgitation. 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."
