It was reported that a patient underwent an atrial fibrillation procedure with a smart touch bidirectional catheter and a noise issue occurred.A signal noise occurred and baseline drifted on the carto 3 system with the first smart touch catheter.The cable was reconnected and changed but the issue continued.The issue was resolved by changing to a second catheter.The second smart touch catheter could not be deflected as intended during ablation after mapping.Furthermore, the contact force value was not displayed on the stockert j70 system.The issue was resolved by changing the catheter to a third catheter.The procedure was completed with no patient consequence.Upon request additional information was received that the noise was observed on the carto and recording system.The deflection and force issues of the second catheter are highly detectable and pose low risk to the patient.However, in taking a conservative approach, this event has been assessed as reportable since we cannot confirm if there were any electrocardiogram signals available for the physician to monitor the patient's heart rhythm during the noise issue of the first catheter.
