Event Description

It was reported to gore a 37 mm gore® cardioform septal occluder was selected to treat an atrial septal defect with a limited aortic rim.No issues were reported during deploying and locking the device.Subsequently, both transesophageal echocardiography and fluoroscopy imaging showed that the right disk appeared to have moved and was now on the left side.An attempt was made to retrieve the device utilizing the retrieval cord but it was not possible to engage the right atrial eyelet and the locking loop with the grey delivery catheter.It was then observed that the grey catheter was kinked at the mandrel.I was also reported that during the retrieval attempts, the device became unlocked.Over the next 1.5 hours, multiple unsuccessful attempts were performed to retrieve the device through a 16 french long sheath, using different lengths and types of snares.Reportedly, a 25 mm goose neck snare initially caught the device and the right atrial eyelet, but due to the inner grey catheter, the device could not be brought into the long sheath.In this situation, the decision was made to send the patient for surgery and the delivery system, retrieval cord and the device were successfully removed.Also, the atrial septal defect was surgically closed.The patient tolerated the procedure.
