65 reports arrived in the 12 months to August 2026, up 20% from 54 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 malfunction (66%), injury (28.7%) and death (5.2%); across all heart-valve, mechanical reports (product code LWQ) death is recorded in 12.7% and malfunction in 10.3%. Event type is the reporter's classification of the report, not a verified outcome.
The device problems coded most often are physical resistance/sticking (41.4%), incomplete coaptation (20.9%) and fracture (15.3%). The patient problems coded most often are aortic valve insufficiency/ regurgitation, heart failure/congestive heart failure and aortic valve stenosis. 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."
