It was reported that during re- pulmonary vein isolation (pvi) procedure, as soon as a lasso eco nav was connected to the piu, the green patches disappeared from the location setup and error 41, 42, 43 were displayed.When rebooting the piu for troubleshooting, piu was rebooting itself in a never ending loop.The physician also stated that the signals taken by cs catheter were measured in a wrong way also on the lasso catheter.Upon following up with the customer, bwi received additional information which is now indicative of a reportable event stated the carto procedure was cancelled and the customer stopped using the smart touch catheter and carto.The case was completed with a non nav ablation catheter without any patient consequence with 1 hour delay.A transseptal puncture was performed prior to the case delay.The physician considered the procedure delay caused a potential risk to this patient since no mapping or using of the carto navigation were possible.
