Event Description
|
It was reported that a patient underwent an id vt (idiopathic ventricular tachycardia) ablation procedure with a optrell mapping catheter there was a lot of noise on nearly every electrode pairing of the catheter.The catheter cable was replaced without resolution.The catheter was removed and there was clot on the catheter (tip of paddle).Act (activated clotting time) was above 400 seconds.The catheter was cleaned and reinserted and there was noise on all electrodes.The catheter was removed again and there was more clot noted (all over the paddle).The act had still exceeded 400 seconds.The ablation catheter was then inserted to complete mapping.No patient consequences were reported.The noise is not mdr-reportable.The clotting is mdr-reportable.

On 23-oct-2023, the bwi product analysis lab received the device for evaluation.The product investigation was subsequently completed.It was reported that a patient underwent an id vt (idiopathic ventricular tachycardia) ablation procedure with a optrell mapping catheter there was a lot of noise on nearly every electrode pairing of the catheter.The catheter cable was replaced without resolution.The catheter was removed and there was clot on the catheter (tip of paddle).Act (activated clotting time) was above 400 seconds.The catheter was cleaned and reinserted and there was noise on all electrodes.The catheter was removed again and there was more clot noted (all over the paddle).The act had still exceeded 400 seconds.The ablation catheter was then inserted to complete mapping.No patient consequences were reported.Device evaluation details: the device was returned to biosense webster for evaluation.A visual inspection, electrical, and patency test of the returned device were performed in accordance with bwi procedures.The device was visually inspected, and thrombus/clot attached on one on electrode of the device's tip was observed.An electrical test was performed, and no electrical issues were found.A patency test was performed, and the device was flushing correctly, no obstructed holes were observed.No irrigation issues were observed.A manufacturing record evaluation was performed for the finished device number lot 31065283m and no internal actions related to the complaint were found during the review.The thrombus/clot issue reported by the customer was confirmed.It should be noted that product failure is multifactorial.In the other hand, the electrical issue reported by the customer could not be replicated during the product investigation; other issues or circumstances may have occurred during the usage of the device that compromised its performance.The instructions for use contain the following recommendation: ecg (electrocardiogram) noise is typically generated as the result of the improper connection of the body surface ecg patch to the patient.This noise is the most significant during ablation.To resolve this situation, verify the proper connection.It is recommended to turn off the notch filter for this verification.As part of biosense webster's quality process, all devices are manufactured, inspected, and released to approved specifications.If additional information is received regarding this event, a supplemental 3500a report will be submitted to the fda.Manufacturer's reference number: (b)(4).
