Medtronic, Inc. has voluntarily suspended worldwide distribution of the Sprint Fidelis family of defibrillation leads because of the potential for lead fractures. In addition, the company recommends against new implants of the leads (Sprint Fidelis Models: 6930, 6931, 6948, 6949).

The Sprint Fidelis leads are used to deliver therapy in defibrillators only, including Implantable Cardioverter Defibrillators (ICDs) and Cardiac Resynchronization Therapy - Defibrillators (CRT-Ds). Approximately 268,000 Sprint Fidelis leads have been implanted worldwide. This action does not affect Medtronic pacemaker patients, a company press release said.

Medtronic, its Independent Physician Quality Panel, and Bruce Lindsay, M.D., Professor of Medicine, Director of Cardiac Electrophysiology, Washington University School of Medicine and President of the Heart Rhythm Society (HRS), do not recommend that patients seek prophylactic replacement of Sprint Fidelis leads, as the risks of removal or insertion of another lead exceed the small risk to patients of a lead fracture. Medtronic has provided patient management recommendations that should reduce risks in the affected population and recommends that patients with questions consult their physicians.

This decision is based on a variety of factors that, when viewed together, indicate that suspending distribution is the appropriate action. Based on Medtronic's extensive performance data, Sprint Fidelis lead viability is trending lower than Medtronic's Sprint Quattro lead at 30 months (97.7% Sprint Fidelis vs. 99.1% Sprint Quattro). This difference is not statistically significant; however, if the current lead fracture rates remain constant, it will become so over time. Medtronic believes that given this performance trend and its ability to identify the primary fracture locations, this action is in patients' best interest.

Lead fractures may present clinically as audible alerts, inappropriate shocks and/or loss of output. Based on current information regarding the 268,000 implanted leads, Medtronic has identified five patient deaths in which a Sprint Fidelis lead fracture may have been a possible or likely contributing factor.

"There is nothing more important to us than the safety and well-being of patients," said Bill Hawkins, president and chief executive officer of Medtronic. "We take all matters of product quality very seriously and believe this action is the right thing to do give currently available information."
