FDA's MAUDE database holds 8,971 reports that name the brand "Gallant HF" (no match), received between August 2020 and August 2026; the manufacturer given most often on reports is St Jude Medical Crm-Sylmar. Spellings of one product vary from report to report.

1,918 reports arrived in the 12 months to August 2026, close to the 1,985 of 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 (87.3%), injury (12%) and death (0.7%); across all defibrillator, automatic implantable cardioverter, with cardiac resynchronization (crt-d) reports (product code NIK) death is recorded in 2.8% and malfunction in 47.2%. Event type is the reporter's classification of the report, not a verified outcome.

The device problems coded most often are over-sensing (68.5%), failure to interrogate (9.2%) and inappropriate/inadequate shock/stimulation (3.3%). The patient problems coded most often are arrhythmia, discomfort and pocket erosion. 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."

Brand, generic and manufacturer names are as written on the reports; product code names come from FDA's device classification. A report counts here when any device it lists carries this brand name after punctuation and capitalisation are normalised. No report narrative, lot number, patient detail or reporter identity is published. See the methodology and sources; FDA's record is authoritative, and corrections are handled within five working days.
