It was reported during an implant of an epicardial lv lead, an attempt to interrogate the device was performed.After multiple attempts and with two different programmers, it was unable to communicate with the device.After discussing the situation, the conclusion was that the battery was early depleted.The device was replaced without problem and the patient was stable after the procedure.

Premature battery depletion was confirmed by analysis.No sources of high current were noted.The cause of the premature battery depletion was consistent with li cluster formation.From these analyses, in the absence of high current draw, it is probable that the premature battery depletion was caused by a lithium cluster induced short circuit.Li clusters are a known depletion mechanism for these advisory products that has been investigated and associated with a field action in october 2016.
