FDA's MAUDE database holds 3,792 reports that name the brand "Automated Impella Controller" (control pump speed cardiopulmonary bypass), received between July 2023 and April 2026; the manufacturer given most often on reports is Abiomed. Spellings of one product vary from report to report.

455 reports arrived in the 12 months to August 2026, down 81% from 2,404 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 (93.4%), death (5.6%) and injury (1%); across all temporary non-roller type left heart support blood pump reports (product code OZD) death is recorded in 12.8% and malfunction in 38%. Event type is the reporter's classification of the report, not a verified outcome.

The device problems coded most often are application program problem (28.6%), battery problem (14.8%) and device sensing problem (13.2%). The patient problems coded most often are cardiovascular dysfunction/insufficiency, hemodynamic instability and cardiac arrest. 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."
