Higher Failure Rate With Riata Leads Affirmed
St. Jude Medical's Riata implantable cardioverter-defibrillator (ICD) leads -- which have been recalled -- are more likely to fail than other leads, a multicenter study confirmed.
The all-cause failure rate was 1.93 percent per patient-year for Riata leads, 0.5 percent for Riata ST leads, and 0.43 percent for Medtronic's Quattro Secure leads, according to Raed Abdelhadi, MD, of the Minneapolis Heart Institute.
The difference between the Riata leads and the Quattro Secure leads was statistically significant (P<0.0001), he reported at the Heart Rhythm Society meeting here.
None of the clinical factors examined in the seven-center study were significant predictors of lead failure.
