848 medical device reports received by FDA name the brand "Syncardia Companion 2 Driver" (external pneumatic driver); the manufacturer given most often on reports is Syncardia Systems; received from July 2012 to July 2026. Brand names are as the reporter or manufacturer wrote them, so one product can appear under several spellings.

5 reports arrived in the 12 months to August 2026, down 67% from 15 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 (96.3%), injury (3.1%) and death (0.4%); across all artificial heart reports (product code LOZ) death is recorded in 10.4% and malfunction in 81.1%. Event type is the reporter's classification of the report, not a verified outcome.

The patient problems coded most often are no patient involvement, hemolysis and loss of consciousness. 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."
