FDA's MAUDE database holds 170 reports that name the brand "Navistar Rmt Thermocool Electrophysiology Catheter" (catheter percutaneous cardiac ablation for treatment of atrial flutter), received between February 2010 and September 2024; the manufacturer given most often on reports is Biosense Webster. Spellings of one product vary from report to report.

0 reports arrived in the 12 months to August 2026, against 1 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 (74.7%), malfunction (18.2%) and death (7.1%); across all catheter, percutaneous, cardiac ablation, for treatment of atrial flutter reports (product code OAD) death is recorded in 3.7% and malfunction in 48.6%. 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 (15.9%), patient device interaction problem (7.6%) and device operates differently than expected (5.9%). The patient problems coded most often are cardiac tamponade, low blood pressure/ hypotension and pericardial effusion. 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."
