PRESS RELEASE: Response Submitted to PACE Affirming Performance of Riata Leads

Response Submitted to PACE Affirming Performance of Riata Leads

ST. PAUL, Minn. -- Nov. 12, 2007--St. Jude Medical said that an article was submitted to Pacing and Clinical Electrophysiology (PACE) journal responding to an editorial concerning the Riata family of leads that is expected to be published on the PACE Web site today. The article, authored by Mark D. Carlson M.D., Roger A. Freedman M.D., and Paul A. Levine M.D., has been accepted and is expected to be published by PACE in the December issue.

In reaffirming the strong and well-documented performance and reliability of St. Jude Medical's Riata leads, the article includes data from St. Jude Medical's returned product analysis, as well as from previously unpublished active, prospective registries (ACT and OPTIMUM) showing that the incidence rate of perforation with Riata is below or at the low end of what has been reported in the clinical literature for incidences of perforation for transvenous defibrillation leads. A summary of the information in the article is available on St. Jude Medical's Web site at or by linking to

"We take a conservative approach in evaluating the performance of our products," said Dr. Carlson, chief medical officer and senior vice president of clinical affairs in St. Jude Medical's Cardiac Rhythm Management Division. "While perforation is a well-known risk in all transvenous lead implant procedures, St. Jude Medical's Riata lead performance is strong as confirmed by the data from both product return analysis as well as through two large, active, prospective registries being conducted by St. Jude Medical. Based on its specific design elements and data analysis to date, we are confident that our Riata Optim family of defibrillation leads, which have been well received by the clinical community, will have the highest reliability yet."

"Perforations are attributable to one or a combination of factors including patient characteristics, the design characteristics of the lead, and implant techniques. As lead designs and implant techniques evolve, it is important that physicians and manufacturers continue to work together to ensure optimal patient outcomes," said Dr. Freedman, director of clinical cardiology and professor of medicine, University of Utah Health Sciences Center, Salt Lake City, Utah, and a member of the St. Jude Medical Independent Leads Medical Advisory Board.
