Manufacturer Narrative

The hardware investigation has begun but it has not been completed at this time.When the investigational analysis has been completed, a supplemental 3500a report will be submitted.If additional information is received regarding this event, a supplemental 3500a report will be submitted to the fda.Manufacturer's ref.# (b)(4).

Event Description

It was reported that a (b)(6) female patient underwent an atrial fibrillation (afib) ablation procedure on (b)(6) 2020 with a coolflow® irrigation pump and suffered acute pulmonary edema.During the procedure, the cable would not allow the catheter to zero.A new cable passed off, and the catheter was able to be zeroed.Case continued without further issues.A total of 87 radiofrequency (rf) applications were done.No immediate patient consequences were reported.Same day, post-procedure, the patient developed acute pulmonary edema (ae1) and was admitted.Unspecified medication was administered.Dc cardioversion was performed.Prolonged hospitalization was required.Issue was resolved, the patient was discharged on (b)(6) 2020.The principal investigator assessed this event as moderate in severity, serious, unlikely related to the study device (qdot micro¿ catheter), not related to the study device (nmarq¿ multi-channel rf generator sw v3.0.1), unlikely related to the study device (nmarq¿ multi-channel rf generator sw v3.0.6), not related to the study device (tx eco ext interface cable (d-1357-03-si), not related to the study device (tx eco cable dongle (em-5050-055f), not related to the non-bwi investigational devices (e.G.Pump, tubing, cables, non-study catheters, etc) and probable index procedure related.Given the implied relationship of adverse event to the study device qdot micro¿ catheter and procedure, this event is to be reported under the marketed device used, the coolflow® irrigation pump, which could have contributed to the causality of the event.

Manufacturer Narrative

It was reported that a 71-year-old female patient underwent an atrial fibrillation (afib) ablation procedure on (b)(6) 2020 with a coolflow® irrigation pump and suffered acute pulmonary edema.Device investigation details: the serial number of the coolflow® irrigation pump provided by the customer was not recognized as a valid serial number.Multiple follow-up attempts to clarify the unit information have been performed, but no additional information was provided.Since there is no clarification, no product investigation can be performed, and the customer complaint cannot be confirmed.Since no serial number was provided, no manufacturer record evaluation could be performed.If additional information is received regarding clarification of the system used in this event, a supplemental 3500a report will be submitted to the fda.If additional information is received regarding this event, a supplemental 3500a report will be submitted to the fda.Manufacturer's ref.# (b)(4).
