It was reported that a (b)(6)-year-old male patient ((b)(6), 164cm) underwent an atrial fibrillation (afib) ablation procedure with a thermocool® smart touch® sf bi-directional navigation catheter and suffered ventricular fibrillation, cardiac arrest, hemopneumothorax with chest tube drainage and bleeding.Although blood pressure was low at the end of the procedure, it was assumed to be due to stimulation of hemostasis and the patient returned to the ward.However, blood pressure did not increase after returning to the ward, and the patient¿s physical condition worsened at night.The patient developed ventricular fibrillation (vf) due to hemopneumothorax/hemorrhagic shock, and resuscitation was performed for about one hour including cardiac massage.Drainage was also performed, and the patient was intubated before dawn.The patient remained intubated at the time of the call and was being followed up on.The physician commented that there was no involvement of biosense webster product because of the problem at the time of puncture, not ablation.No abnormalities were observed before/during product use.Additional information was received on 16-dec-2021.It was reported that the physician¿s opinion on the cause of this adverse event is that this is procedure related.The patient outcome of the adverse event was reported as unchanged.Prior to noting the adverse event, ablation was performed.There was no evidence of a steam pop.No error messages were observed on the biosense webster equipment during the procedure.Conservatively, this was assessed as mdr reportable as ablation was performed.Should additional information become available, this will be reassessed accordingly.
