St. Jude Warns Physicians of Potential Problem with QuickSite and QuickFlex LV CRT Leads

St. Jude announced it is proactively informing physicians about visual observations of externalized conductors on the silicone end of QuickSite® and QuickFlex® Left-Ventricular Leads, used to connect Cardiac Resynchronization Therapy devices to the heart.

The announcement noted that there have been no reports of patient injury or loss of therapy due to externalized conductors in these leads, but as a conservative measure, St. Jude Medical is communicating with physicians about the incidence rate so they have the most updated lead performance information with which to make important patient care decisions.

According to the announcement, “St. Jude Medical has confirmed 39 cases of externalized conductors, out of 171,000 QuickSite and QuickFlex leads sold worldwide, resulting in a current reported incidence rate of 0.023 percent, or 2.3 in 10,000. Because these leads continue to function normally, the company expects that this rate is under-reported. Based on an analysis of leads returned to the company and recent fluoroscopic images of implanted leads still in clinical use, St. Jude Medical estimates that 3 to 4 percent of QuickSite and QuickFlex leads may exhibit externalized conductors. As a result of this estimated rate, the company felt it was prudent to communicate with physicians about the externalized conductors at this time.”

St. Jude also announced they will no longer sell these lead models.
