It was reported that a female patient underwent an ablation procedure for atrial fibrillation under general anesthesia with a pentaray navigational eco catheter and suffered ventricular fibrillation requiring defibrillation.During the mapping phase with the pentaray navigational eco catheter, the patient went into ventricular fibrillation.Defibrillation converted the patient to normal sinus rhythm.Remainder of procedure was aborted.It was noted that the patient was initially in atrial fibrillation with a prolonged qt interval secondary to a medication.Physician wanted to postpone the procedure until the medication was fully metabolized and the qt interval returned to normal.Patient was on inpatient status prior to the procedure.Patient required hospitalization over the weekend to confirm that medications fully metabolized and the prolonged qt interval remained normalized.Patient fully recovered.Physician¿s opinion regarding the cause of the adverse event is that it was related to patient condition.Physician indicated that the prolonged qt interval was a result of medication that the patient received.Transseptal puncture was performed with an unspecified needle.It was noted that the patient was under general anesthesia for approximately 2 hours prior to aborting the procedure.The smarttouch bidirectional catheter was plugged into the patient interface unit, but was not placed in the patient¿s body.No ablation was performed.Physician does not consider that aborting the procedure may have caused or contributed to a death or a serious injury to the patient.It was also reported that a not reportable catheter sensor error 6150 displayed on the carto 3 system.The soundstar eco catheter was replaced and the issue resolved.The mapping catheter was not.
