Event or Problem Description
It was reported that a 14mm amplatzer septal occluder was selected for implant on (b)(6) 2024.The patient had 2 atrial septal defects (asd).The first asd was measured as 14mm and the second defect was 18mm.Sizing was determined with transesophageal echocardiography (tee) and a non-abbott sizing balloon.The patient was in sinus rhythm during the procedure.Tee was used during the procedure.The 14mm occluder was implanted.An 18mm amplatzer septal occluder was selected for implant on the second asd.Upon implant, a large residual shunt was detected, and it was observed that the device migrated.The device was removed from the patient via transcatheter snare and replaced with a new 24mm amplatzer septal occluder.Upon implant, the device migrated due to one of the edges of the devices not taking to the defect because of its small size.It was noted during implant of the 24mm occluder, the device made contact with the 14mm occluder, causing the 14mm occluder to embolize to the descending aorta.The 24mm occluder and the 14mm occluder were both removed from the patient via transcatheter snare.The cause of the embolization and migrations was believed to have been due to the complexity of the two defects.The implant of each device was difficult due to complex anatomy.The patient remained hemodynamically stable throughout the procedure.There were no adverse effects to the patient.The patient status was hospitalization.
Additional Manufacturer Narrative
An event of device migration and residual shunt was reported.A returned device assessment could not be performed as the device was not returned for analysis.The device history record was reviewed to ensure that each manufacturing and inspection operation was performed and the product met all defined manufacturing specifications.Information from the field indicated that the first asd was measured as 14mm and the second defect was 18mm.The 14mm occluder was implanted.The 18mm occluder was selected for implant on the second asd.Upon implant, a large residual shunt was detected, and it was observed that the device migrated.Therefore, the device was removed from the patient via transcatheter snare and replaced with a new 24mm occluder.Upon implant, the device migrated due to one of the edges of the devices not taking to the defect because of its small size.It was noted during implant of the 24mm occluder, the device made contact with the 14mm occluder, causing the 14mm occluder to embolize to the descending aorta.Then, the 24mm occluder and the 14mm occluder were both removed from the patient via transcatheter snare.The cause of the embolization and migrations was believed to have been due to the complexity of the two defects.The implant of each device was difficult due to complex anatomy.Based on the available information, the cause of the reported migration appears to be related to procedural condition and patient conditions (due to the complexity of the anatomy).The cause for the reported residual shunts could not be undetermined.There is no indication of a product quality issue with regards to manufacture, design, or labeling.
