Manufacturer Narrative

The biosense webster, inc.Product analysis lab received the device for evaluation.The analysis has begun but is not completed at this time.When the investigational analysis has been completed, a supplemental 3500a report will be submitted.If information is obtained that was not available for the initial report, a follow-up report will be filed as appropriate.Manufacturer's reference number: (b)(4).

Event Description

It was reported that a (b)(6) male patient (b)(6) underwent an atrial fibrillation (afib) ablation procedure with a navi-star¿ thermo-cool¿ electrophysiology catheter and suffered cardiac tamponade requiring pericardiocentesis, surgical intervention, and prolonged hospitalization.It was reported that while ablating in the left atrial appendage, the physician felt a steam pop.The patient had a slight drop in their blood pressure.The patient had a pericardial effusion that was confirmed via the ice catheter.The patient had a pericardiocentesis and 5.5 liters or 5500 ccs of fluid was removed.Cardiovascular surgeons were standing by.They were able to close the left atrial appendage with a closure device to stop the effusion.The patient was stable during the entire procedure.The patient stayed overnight for observation in the icu.The physician felt the effusion was from the steam pop that occurred at the base of the appendage.They used a maximum of 45 watts during the ablation.Additional information was received on 13-mar-2022.The lot number is unknown as the catheter packaging was thrown away.The patient outcome of the adverse event is improved.The patient required extended hospitalization as the patient stayed in the icu overnight for recovery from blood loss and monitoring of effusion with drain left in place.A smartablate generator with ref # m490002 and sn # (b)(4) was used.A transseptal puncture was performed with a baylis, nrg transseptal needle standard curve c0, nrg-e-hf-71-c0.Prior to noting the pericardial effusion, ablation was performed.An irrigated catheter was used in the event, the flow setting was 30ml/min (per ifu for navistar thermocool catheter above 30w).Correct catheter settings were selected on the generator.The pump was switching from ¿low¿ to ¿high¿ flow during ablation.Force visualization features used were graph, dashboard, and vector.The visitag module was used, the parameters for stability used were 3mm, 5s @ 2mm tag size.No additional filter was used with the visitag.Time color option was used prospectively.

Manufacturer Narrative

The device evaluation was completed on 19-apr-2022.It was reported that a 76-year-old male patient (110 kgs) underwent an atrial fibrillation (afib) ablation procedure with a navi-star¿ thermo-cool¿ electrophysiology catheter and suffered cardiac tamponade requiring pericardiocentesis, surgical intervention, and prolonged hospitalization.It was reported that while ablating in the left atrial appendage, the physician felt a steam pop.The patient had a slight drop in their blood pressure.The patient had a pericardial effusion that was confirmed via the ice catheter.The patient had a pericardiocentesis and 5.5 liters or 5500 ccs of fluid was removed.Cardiovascular surgeons were standing by.They were able to close the left atrial appendage with a closure device to stop the effusion.The patient was stable during the entire procedure.The patient stayed overnight for observation in the icu.The physician felt the effusion was from the steam pop that occurred at the base of the appendage.They used a maximum of 45 watts during the ablation.Device evaluation details: the product was returned to biosense webster for evaluation.A visual inspection and an evaluation of all features of the device were performed following bwi procedures.Visual analysis revealed that the sleeving was cut to gain access to the anchor.Per the event, several tests were performed.The magnetic, temperature features were tested, and no issues were observed.In addition, the product was deflecting and irrigating correctly.No malfunctions were observed during the product analysis.During product analysis, the lot number was verified to be 30433984m.This was verified by electronically erasable programmable read only memory (eeprom) file.A manufacturing record evaluation (mre) was performed for the finished device [30433984m] number, and no internal actions related to the reported complaint condition were identified.Based on the mre, the d 4.Lot, d 4.Expiration date, h 4.Device manufacture date have been updated.No malfunction was observed during the product analysis.The root cause of the adverse event remains unknown.There may have been other circumstances or issues that occurred during the use of the device that could not be replicated during the analysis.The ifu (instruction for use) states that careful catheter manipulation must be performed to avoid cardiac damage, perforation or tamponade.The root cause of the adverse event remains unknown.There may have been other circumstances or issues that occurred during the use of the device that could not be replicated during the analysis.As part of biosense webster¿s quality process, all devices are manufactured, inspected, and released to approved specifications.If additional information is received regarding this event, a supplemental 3500a report will be submitted to the fda.Manufacturer's reference number: (b)(4).
