CFX MANAGER ERROR SOFTWARE

In the last 2 years, a few software issues related to MDT programmers as well as remote monitoring applications have been identified. This case illustrates a potentially fatal error in the new tablet‐based MDT CareLink™ SmartSync™ Device Manager resulting in overestimation of battery longevity when the device is nearing RRT indicator. Until this software error is corrected, this issue could recur.

They further acknowledged this to be the first reported occurrence of this behavior, and pledged to correct this error by a software update in a future release of the SmartSync application. The root cause was attributed to an error in the rewriting of Percepta application software from the Model 2090 programmer to the SmartSync platform (application model number D00U004). Also, other devices supported by the SmartSync Device Manager are not affected by this error according to the MDT report. This error does not occur with older programmers including Model 2090, Encore, or with CareLink session. This overestimation error only occurs when the device is interrogated with a SmartSync Device Manager and the device is within approximately 180 days of its Recommended Replacement Time (RRT) indicator. After analyzing the data, on February 7th, 2020, MDT confirmed the potential for the Remaining Longevity Estimate to be inaccurate (overestimated) when the device approaches RRT indicator.

The case was reported to the MDT company for assessment.

CFX MANAGER ERROR GENERATOR

Given the clinical status of the patient, consistent low battery voltage readings, and despite the projected longevity of the table‐based programmer, a decision was made to proceed with device generator change which was performed without any complications. When the device was interrogated with a Model 2090 programmer, the remaining longevity was 1 month with a battery voltage of 2.61 V. As patient was pacemaker dependent and the battery voltage of 2.61 V was inconsistent with the projected longevity, an older conventional device programmer (CareLink™ 2090) was used to determine the exact device battery status.

However, on the day of her procedure, her device interrogation using CareLink™ SmartSync™ Device Manager (Percepta Application Model Number D00U004) displayed a remaining longevity of 4 years and battery voltage of 2.61 V. She was scheduled to have a generator replacement procedure on January 22nd, 2020. C, Device interrogation with a conventional Model 2090 programmer on the same day showed the remaining longevity was 1 month B, Device interrogation using tablet‐based CareLink™ SmartSync™ Device Manager on January 22 nd, 2020, displayed a remaining longevity of 4 years. Here, we report a case of a pacemaker‐dependent patient whose MDT CRT‐P device was identified to have reached RRT status according to the remote monitoring but interrogation of his device by the new CareLink SmartSync™ displayed a remaining longevity of 4 years.Ī, Remote monitoring of device on Dec 3 rd, 2019, demonstrated the device to be at RRT with projected battery longevity of 2 months.

CFX MANAGER ERROR PORTABLE

Medtronic (MDT) CareLink SmartSync™ is the next‐generation tablet‐based device manager that uses BlueSync™ technology for wireless connectivity and functions as a portable device programmer and pacing system analyzer to replace the older Medtronic CareLink programmers. With the widespread availability of mobile technologies, there is a concerted effort by most major device manufacturers to replace the traditional cardiac device programmers with mobile platforms. In cases of national emergencies such as covid‐19 virus pandemic, remote monitoring of CIEDs could safely substitute the majority of in‐person visits whereby reducing the spread of the infection, a policy that we have adopted in our institution. Widespread adoption of remote monitoring has brought additional safety and convenience. Interrogations of cardiac implantable electronic devices (CIEDs) using traditional device programmers have been the cornerstone of device monitoring and follow‐up.
