Medtronic International Limited would like to notify healthcare professionals of the loss of LV pacing that may occur with all models of Claria MRI™ CRT-D SureScan™ and Amplia MRI™ CRT-D SureScan™ devices. Medtronic became aware that when a patient with AdaptivCRT enabled (shipped setting) is subsequently programmed to MVP mode and then re-programmed back to DDD or DDDR, AdaptivCRT is not re-enabled. When this programming sequence occurs, LV pacing is not delivered, despite parameters indicating AdaptivCRT is enabled. This will result in RV only pacing, which may be undesirable for the patient. LV pacing will remain disabled until a specific programming sequence is manually completed. A software update is being developed to address this issue. In the meantime, healthcare professionals are advised to follow the programming recommendations to manage patients with the susceptible device until the software update is available. Please refer to letter for details.
