Event Description

It was reported that a male patient in 70s underwent an ischemic ventricular tachycardia (isvt) ablation procedure with two navistar® rmt thermocool® electrophysiology catheter¿s.The patient suffered a cardiac tamponade requiring a pericardiocentesis.The patient suffered a pericardial effusion.The effusion was initially noted during intracardiac echo (ice) (soundstar) imaging pre-transseptal access.The case was continued while monitoring the effusion.After gaining transseptal access, mapping, and some ablation (with the second ablation catheter- lot #: unknown), the effusion had grown.A pericardiocentesis was performed, with about 800 ml removed.The patient was stable.The adverse event was discovered during use of biosense webster, inc.The physician stated she was unsure of the cause of the adverse event.The patient outcome of the adverse event was unknown.It is also unknown if the patient required extended hospitalization.Transseptal puncture was performed with a versacross wire with fixed sheath- baylis.Prior to noting the cardiac tamponade, ablation was not performed.There was no evidence of a steam pop.The event occurred during pre-transseptal access.The irrigated catheter flow setting was rmt tc, 15/30ml.No error messages were observed on biosense webster equipment during the procedure.The procedure was abandoned.There was no evidence of any effusion present before the procedure.Also, it was reported that the second electrode on the initial ablation catheter (navistar® rmt thermocool® electrophysiology catheter /lot number: 30829977m) was bad.It was black on the map and had noisy signals.The cable was replaced without resolution.The catheter was replaced with a navistar® rmt thermocool® electrophysiology catheter (lot # unknown) and the issue resolved.The procedure was continued.Additional information was received.The biosense webster, inc.Representative¿s knowledge, the patient did not require extended hospitalization.Relevant tests: prior to the case, an echo was performed on the patient and no effusion was noted.No other relevant history.A transseptal puncture was performed with a baylis versacross access solution with pigtail wire.There was no evidence of steam pop.Effusion was noted prior to ablation.Flow settings were standard for st ablator; 17 ml/min for <30w, 30 ml/min for >30w.No error messages were observed on biosense webster equipment.The issue of the second electrode was black on the map and had noisy signals was assessed as not mdr reportable.The risk to the patient was low.Since the adverse event is life threatening and it might result in permanent impairment of a body function or permanent damage to a body structure; or it could require medical or surgical intervention to prevent permanent impairment of a body function or permanent damage to a body structure, it is to be considered serious and mdr-reportable.The adverse event was assessed as mdr reportable under both of the navistar® rmt thermocool® electrophysiology catheter¿s used in the procedure.
