  Boston Scientific Cardiac Resynchronization Therapy (CRT)labeled as: 1. VALITUDE CRT-P EL, Model Number U125; 2. VALITUDE CRT-P EL MRI, Model Number U128; 3. VISIONIST CRT-P EL, Model Number U225; 4. VISIONIST CRT-P EL, Model Number U226; 5. VISIONIST CRT-P EL MRI, Model Number U228.

  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

  VALITUDE CRT-P, EL (Model Number U125) and EL MRI (Model Number U128)

  A subset of devices from the ACCOLADE Family of Pacemakers and CRT-Ps, built before September 2018, have an increased potential to initiate Safety Mode during telemetry or other normal, higher-power operations due to latent high battery impedance.

  INVIVE CRT-P, Model Numbers: a) V172 b) V173 c) V182 d) V183 e) W172 f) W173

  The dual chamber INGENIO family pacemakers or cardiac resynchronization therapy pacemakers (CRT-Ps) may initiate Safety Mode later in device life (i.e., prior to reaching the Explant battery indicator) when the device's battery exhibits high internal impedance. This latent battery condition puts a device at risk for system resets to occur due to temporary high-power consumption related to telemetry attempts and subsequent reversion to Safety Mode to maintain back-up pacing. Although therapy is still provided when a device is in Safety Mode, replacement is required. - Only dual chamber INGENIO family pacemakers and CRT-Ps built with the Extended Life (EL) battery are included within this advisory population
