Event Description

It was reported that a patient underwent an idiopathic ventricular tachycardia (idvt) ablation procedure with a carto® 3 system external reference patches and the patient suffered cardiac arrest and possible anaphylactic reaction.While beginning to intubate the patient the anesthesia doctor pushed vancomycin and the patient coded.The bwi representative stated that there were still visible p waves and qrs on the ecg but no carotid pulse.Chest compressions were performed as well as 7 cardioversions.A lift team was brought in on standby and the pharmacy came to push meds.The patient stabilized and the pulse returned, the case then proceeded without further incident.The patches were the only biosense webster product involved at the time of the incident.The doctor inquired if the carto patches could cause anaphylactic shock.The bwi representative requested information about the adhesive material on the patches and was directed to medical affairs.The patches were discarded and are not available for return.Conservatively this event will be an adverse event for cardiac arrest, anaphylactic reaction.It is most likely that the vancomycin and /or the anesthesia medications that were given for intubation were the cause but because of the doctor¿s concern if the carto patches could cause anaphylactic shock.Should more information become available, it will be reviewed and processed accordingly.
