Core Tip

Core Tip: We analyzed post-marketing surveillance data from the Food and Drug Administration Manufacturer and User Facility Device Experience database to outline the most common adverse events and modes of failure encountered with Fractional Flow Reserve (FFR) coronary guidewires. Guidewire tip fracture was the most commonly reported mode of failure, in 35.8% of cases; retained guidewire tip was the most common patient complication (53.4% of cases). FFR is an important frontline measurement in the cardiac catheterization laboratory to assess intracoronary physiology. Our analysis demonstrates that in real-world practice, FFR guidewire failures can occur because of myriad mechanisms and result in patient complications.
