Event Description
|
It was reported that a patient underwent an atrial fibrillation (afib) procedure with a carto 3 system.At the beginning of fast anatomical mapping (fam) creation in the left atrium with the a lasso catheter, a metal distortion error on the chest patch was observed.This was due to steep lao of the fluoroscopy system and closeness of the image intensifier to the chest.The ii was raised up and the error disappeared.Fam was then collected.Later in the study, no errors appeared but a small shift in the left inferior pulmonary vein (lipv) and right inferior pulmonary vein (ripv) were observed by the operator.The catheters were no longer lining with the left atrium map which they had created earlier leading them to believe that there was a map shift.The distance was the size of the variable lasso catheter loop approximately 15mm.The cause of the shift was unknown.The patient was not cardioverted.The patient could have moved but there was no indication that this had occurred.There was no delay to the procedure.The procedure was completed.There was no adverse consequence to the patient.The metal distortion error was assessed as not reportable as the most likely consequence was an intraprocedural delay.The potential risk that it could cause or contribute to a serious injury or death was remote.This map shift issue with no error message was assessed as a reportable malfunction as there is a potential risk to the patient.
