Event Description
|
It was reported that a female patient underwent repeat persistent atrial fibrillation (afib) ablation procedure with a thermocool® sf nav bi-directional catheter and a smartablate¿ system rf generator and suffered atrioesophageal fistula and air embolism requiring hospitalization and death.A female patient born in (b)(6) underwent a repeat pulmonary vein isolation (pvi) using thermocool® sf nav bi-directional catheter and lasso® nav eco variable catheter without any problems.The patient was sent home after uncomplicated procedure without any known side effects.Patient was hospitalized approx.2 weeks after the procedure in another hospital due to breast pain and malaise.A computed tomography (ct) scan didn¿t show any conspicuousness.During that time the patient¿s condition deteriorated showed signs of worsening outcome.Gastroscopy revealed atria-esophageal fistula in patient.The patient developed air embolism and fistula was treated with clips.Pressure chamber treatment was performed.Patient was in intensive care at the moment of the call in very serious condition with dire prognosis and subsequently expired.The physician¿s opinion on the cause of this adverse event is that it was procedure related.During the procedure the visitag module was used with unknown stability parameters and total time for color option.No additional visitag filters were used.The smartablate¿ system rf generator was set to power control mode with default settings for thermocool® sf catheters.There was no perforation suspected during procedure.No error messages were observed on biosense webster equipment during the procedure.To prevent esophageal injury low power (25w), low duration in ablation (30s maximum duration) was used.Based on the event details a strong argument can be made that the air embolism did not occur during the procedure but rather was a cascade of harms from the atrioesophageal fistula.Therefore, air embolism will only be conservatively coded only under the thermocool® sf nav bi-directional catheter only.
