Event Description

It was reported that a patient underwent a cardiac ablation procedure with a thermocool® smart touch® sf bi-directional navigation catheter and a when the catheter was removed from the patient¿s body, visual inspection revealed that that thrombus had adhered to the catheter (tip electrode, distal side).When ablating the anterior wall of the right pulmonary vein (rpv), an increase in impedance value was observed, so ablation was interrupted.The ablation was conducted again, but there was no improvement on impedance value.The catheter was removed from the patient's body, and visual inspection revealed that thrombus had adhered to the catheter.The catheter was replaced to complete the procedure.No adverse patient consequence was reported.Additional information was received, and it was reported that when the thrombus occurred, irrigation flow was kept low flow due to wrong setting.As the generator setting was for 4mm ablation catheter, it remained ¿low¿ irrigation flow during ablation.Heparinized normal saline was used.The rise in impedance is not mdr reportable as the change in impedance was not reported to exceed any cut off value and no error was displayed regarding impedance.The thrombus issue is mdr reportable.
