It was reported that the patient experienced a stroke.During a pulmonary vein isolation (pvi) and atrial tachycardia (at) ablation procedure, an atrial tachycardia map was made with an intellamap orion catheter of the right atrium and was successfully ablated with the intellanav mifi oi catheter at a power setting of 30w in the high lateral right atrium.A subsequent transeptal procedure was done, and a map was made of the left atrium and pulmonary vein ostia with the intellamap orion.A single ablation lesion was made on the anterior antral right superior pulmonary vein with the intellanav mifi oi at 30w power to isolate the vein.The procedure was completed successfully and the patient was woken from general anesthesia.The following day, it was noted that the patient had a stroke with notable slurred speech.The physician also stated that he recalled the intellamap orion catheter looked fuzzy on intracardiac ultrasound during the procedure and he suspects the stroke could have been related to an thrombus embolization from the orion catheter.He did state that this was not conclusive and the stoke could have originated from another "emoblic" source.It should be noted that the patient withheld their novel anticoagulant the day before the procedure under the direction of the physician.During the procedure, after initial femoral access, the patient was anticoagulated with heparin maintaining a target act>300ms throughout the procedure.The ablation impedance, power, and temperature were all within normal parameters during ablation and throughout the procedure.The flow rate through the ablation catheter was 2cc/min standby and 17cc/min during ablation.The orion was removed from the body during ablation.
