Event Description
|
It was reported that a patient underwent an ablation procedure for paroxysmal atrial fibrillation with a carto® 3 system and when a second indifferent electrode was connected to the smartablate generator during radiofrequency delivery, a map shift occurred.The indifferent electrode was removed, and the map shift seemed to correct itself.The electrode was reconnected again; in stand-by mode.The map shift occurred again, moving the map 1.5 cm.The procedure was successfully completed without patient consequences.The map shift issue was seen during both mapping and ablating and the system did not display any error or alert messages when the map shift occurred.The map shift was noticed because the location of the coronary sinus catheter relative to the snapshot was off, and the lasso was outside of the pulmonary vein sound contour.The physician did not perform cardioversion prior to the map shift and the patient did not move before detecting the shift.The map shift, no error message, no patient movement/cardioversion issues have been assessed as reportable.
