0 reports arrived in the 12 months to August 2026, and none in the 12 months before.

The event types recorded are injury (83%), death (12.7%) and malfunction (4.1%); across all ventricular (assist) bypass reports (product code DSQ) death is recorded in 14.6% and malfunction in 37%. Event type is the reporter's classification of the report, not a verified outcome.
The device problems coded most often are other (for use when an appropriate device code cannot be identified) (70.9%), explanted (28.9%) and replace (22.7%). The patient problems coded most often are hospitalization required, surgical procedure and surgical procedure, repeated. 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."
