FDA's MAUDE database holds 1,064 reports that name the brand "CG Future Band" (ring annuloplasty), received between March 2007 and August 2026; the manufacturer given most often on reports is Medtronic Heart Valves Division. Spellings of one product vary from report to report.

131 reports arrived in the 12 months to August 2026, up 54% from 85 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 injury (95.8%), malfunction (3.1%) and death (1.1%); across all ring, annuloplasty reports (product code KRH) death is recorded in 8.1% and malfunction in 2.2%. Event type is the reporter's classification of the report, not a verified outcome.

The device problems coded most often are insufficient device problem information (62.9%), intravalvular regurgitation (6.7%) and patient device interaction problem (5.9%). The patient problems coded most often are mitral regurgitation, mitral valve insufficiency/ regurgitation and mitral 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."
