Event Description

It was reported that a male patient underwent a persistent atrial fibrillation (afib) ablation procedure with a thermocool® smart touch® sf bi-directional navigation catheter and a smartablate¿ system irrigation pump and suffered air embolism (requiring coronary angiogram and 100% high flow o2) and ventricular fibrillation (requiring defibrillation).During the procedure, the physician noticed that the flush line that went from the st.Jude sl1 long sheath to the ablation catheter was dry, and there were changes in the ecg after that.Air embolism was confirmed by intracardiac echo (ice), and the right ventricle was not moving right on the ultrasound.Coronary angiogram was performed and 100% high flow o2 was applied.The patient was then defibrillated multiple times, the physician believes that the defibrillation was what broke up the embolism.The patient was reported to be in stable condition and was moved to ct for a brain scan to see if air went into the brain.There¿s no information regarding extended hospitalization and patient¿s outcome.It was confirmed that the sheath used was a st.Jude sl1 long sheath, no bwi preface sheath was used.Biosense webster manufacturer's reference number (b)(4) has two reports related to the same event: mfr # 2029046-2019-03124 for product code: d134805 (thermocool® smart touch® sf bi-directional navigation catheter).Mfr # 2029046-2019-03125 for product code: m490008 (smartablate¿ system irrigation pump).

Manufacturer Narrative

On (b)(6) 2019, the biosense webster inc.¿s medical safety officer (mso) received additional information about the event from speaking with the clinical account specialist (cas) that reported this event.The following information was received: the pressure bag line connected to the long sheath used in the procedure was noted to have air in it.A valve mechanism on the pressure bag which was supposed to control flow on the long sheath had been stuck open resulting in emptying of the pressure bag and air entering into the long sheath which then entered the patient.There was no air in the smartablate tubing system or catheter.The air entered the patient through the long sheath after the sheath had gone transseptal.Patient fully recovered from the incident.The air embolism should not be attributed to the smartablate¿ system irrigation pump and this product should be considered concomitant product; therefore, this event is no-longer mdr-reportable for the air embolism reported under the smartablate¿ system irrigation pump.Manufacturer¿s ref # (b)(4).
