It was reported a patient underwent a cardiac ablation procedure and patient experienced cardiac tamponade treated with a pericardiocentesis.Rf needle was not used for transseptal puncture.Ablation was performed.One hour after the procedure was started and during the ablation, impedance increased mid-ablation.The ablation was immediately stopped, but the blood pressure decreased.No steam pops have been confirmed.Pericardial drainage was performed and blood pressure was stabilized.The patient was conscious, but returned to the icu for monitoring.The patient's condition improved at this point.No error messages on equipment during procedure.The physician's opinion on the cause of the adverse event is the procedure.The physician mentioned that right ventricular outflow tract, the site of ablation, is normally indented, but the patient's right ventricular outflow tract was appeared even more indented than others on the computed tomography (ct) scan.The patient's breath was deep, so the tip of the catheter may have been stuck in the indented hollow during ablation, resulting in cardiac tamponade.The patient became stable and moved to general ward on the day after the procedure.Patient fully recovered.
