Reason

Updated software, Brady software maintenance release 6 (SMR6), is now available for the ACCOLADE" family of pacemakers and cardiac resynchronization therapy pacemakers (CRT-Ps)1 and the advisory population is expanding to include all CRT-P and dual-chamber extended life (DR-EL) devices. Dual chamber modes are specifically indicated for treatment of the following: " Conduction disorders that require restoration of AV synchrony, including varying degrees of AV block " VVI intolerance (i.e., pacemaker syndrome) in the presence of persistent sinus rhythm " Low cardiac output or congestive heart failure secondary to bradycardia

Identifiers

" ACCOLADE DR-SL and SR-SLs with a use-by-date (UBD) on or before 30 June 2025 are included in the advisory population. Model number alone will not precisely identify individual DR-SL or SR-SL devices in the advisory population. To determine if a device is affected, enter a model/serial into the device lookup tool at www.BostonScientific.com/lookup.
