Event Description
|
It was reported that a patient underwent an atrial fibrillation (afib) procedure with a carto 3 system.A map shift of approximately 5cm occurred during mapping and no error message populated.The map shift was discovered because of the inconsistency between the fast anatomical map and contact force.There was no patient movement and no cardioversion was performed.The physician had to remap the chamber to continue the procedure.There was an hour and half delay.According to the physician the delay issue could not cause or contribute to any serious injury of the patient.Only discomfort was reported.The procedure was completed with no patient consequence.Additional information has been requested.However, no further information has been made available.The procedure delay was assessed as not reportable as there was no risk to the patient's health status indicated.The patient's discomfort has been assessed as non serious and therefore not reportable as there is no evidence of medical/surgical intervention or prolonged hospitalization.The map shift with no error message has been assessed as a reportable malfunction as such map shifts could potentially be caused by a system malfunction and there is a potential risk to the patient.
