FDA's MAUDE database holds 753 reports that name the brand "HeartMate 3 VAD Modular Cable" (ventricular assist bypass), received between November 2017 and August 2026; the manufacturer given most often on reports is Thoratec. Spellings of one product vary from report to report.

95 reports arrived in the 12 months to August 2026, up 46% from 65 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 (93.5%), injury (6.4%) and death (0.1%); 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 mechanical problem (40.5%), electrical /electronic property problem (23.8%) and communication or transmission problem (15.1%). The patient problems coded most often are dizziness, dyspnea and syncope/fainting. 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."
