Event Description
|
It was reported that a patient underwent an atrial fibrillation (afib) procedure with a carto 3 system.During mapping, there were two map shifts of at least 1 cm with no error messages.There was also no cardioversion performed and no patient movement prior to these map shifts.Remapping was performed and the issue was resolved.The procedure was completed with no patient consequences.This issue has been assessed as a reportable malfunction as such map shifts without an error message could potentially be caused by a system malfunction.

(b)(4).It was reported that a patient underwent an atrial fibrillation (afib) procedure with a carto 3 system.During mapping, there were two map shifts of at least 1 cm with no error messages.There was also no cardioversion performed and no patient movement prior to these map shifts.Remapping was performed and the issue was resolved.The procedure was completed with no patient consequences.Issue was investigated by the device manufacturer and it was found that after a short time since the study was started there was movement of the upper part of the patient torso which is not recognized by the back patch.It resulted with a ~13 mm shift of the chest patch average position while the back patch did not move.Map shift issue is documented in the instructions for use (ifu) when there is not any movement of the back patches however the patient moved in such a way as to cause a shift in the heart's anatomical position.Issue was not duplicated next cases.The device history record (dhr) review was performed by the manufacturer and no anomalies were noted in manufacturing or servicing of this equipment.
