It was reported that a patient underwent a cardiac ablation with a thermocool® smart touch® sf bi-directional navigation catheter and an octaray mapping catheter.The patient experienced cardiac perforation/tamponade that required pericardiocentesis and surgical intervention; however, the patient died.Perforation of left atrial roof with the octaray mapping catheter during mapping.Surgical operation (open chest) was performed.Atrial septal puncture was performed by rf needle.Ablation was not performed before pericardial effusion or tamponade was identified.Patient required extended hospitalization but the outcome was patient death.The physician¿s assessment of the health problem was critical.The physician's opinions on the relationship between the event and the product was that perforation may have occurred with either the sheath or the mapping catheter, but which one is unknown.After pre-mapping was performed, the physician noticed a drop in blood pressure during pulmonary vein isolation (pvi).He/she did not notice the drop in blood pressure initially because it could not be confirmed.No abnormalities observed prior to use of the products.Steam pop was not confirmed.Additional information was received.Physician's opinion on the cause of death was cardiac/respiratory arrest due to cardiac tamponade.Since this was the 2nd af procedure, pre-mapping was performed as usual and ablation was performed.After ablation, a drop in blood pressure was noticed, and upon fluoroscopic confirmation, the silhouette of the left ventricle was not moving at all.Tamponade was found near the left atrial roof, so performed drainage immediately.No cardiac or respiratory arrest were observed at that time.Subsequently, as hemostasis was not performed by drainage, contacted surgeon for open chest surgery.Before the chest was opened, the blood pressure was maintained at about 100 mmhg.When the chest was opened, perforation of the roof vein was observed, and pressured hemostasis was performed.Blood pressure at this time was maintained at about 70-80 mmhg.After repairing the damaged roof vein, the patient's condition suddenly got worse.According to the physician, blood had accumulated in abdominal cavity and the abdomen had swelled.Placed the patient on extracorporeal cardiopulmonary bypass, but could not be saved.The sheath was medikit sheath.No issue was reported on the carto 3.Servicing for the carto 3 was not needed at this time.No repair was performed.Probably a perforation occurred by the octaray mapping catheter.No device malfunctions were reported.The adverse event was assessed as mdr reportable under both the thermocool® smart touch® sf bi-directional navigation catheter and an octaray mapping catheter.
