It was reported that on (b)(6) 2023, a 5-4mm amplatzer duct occluder was chosen for implant for a 10 week old, 2 kg patient with the following patent ductal arteriosus (pda) measurements: pulmonary artery diameter of 3.8mm, aortic diameter of 4.4mm, and pda length of 7.9mm.The amplatzer duct occluder was chosen due to the minimum ductual diameter.An unknown abbott delivery system was utilized.Fluoroscopy and transesophageal echocardiogram (tee) were used during procedure for imaging.The patient was in sinus rhythm during procedure.The device was deployed, and it initially pulled through the duct into the pulmonary artery.The device was recaptured and repositioned.The device was evaluated closely prior to release, and it was positioned at the pulmonary artery end of the duct with mild left pulmonary artery obstruction and no aortic involvement.A stability check was performed prior to release.Upon release, the device moved forward in the duct towards the aorta.Post implant revealed an aortic obstruction with a peak gradient of 9mmhg.The patient was transferred to another hospital for evaluation.On (b)(6) 2023, the patient had open heart surgery to explant the device.A surgical ligation was performed to close the pda defect.The patient status was reported as stable.

An event of device migration upon release towards the aorta causing aortic obstruction 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 specifications.Based on the information received, the cause of the reported incident could not be conclusively determined, however potentially be related to the user not following the the ifu.There is no indication of a product quality issue with respect to labeling design or manufacturing of the device.A 5-4 mm amplatzer duct occluder ii was used in patient weighting less than 6kg.Please note that per the instructions for use, "contraindications: ¿ patients weighing less than 6 kg ¿ patients less than 6 months of age".
