It was reported that on (b)(6) 2021, a 3mm/4mm amplatzer duct occluder ii was selected for implant for the patient's patent ductus arteriosus (pda).The device was successfully implanted in the pda, but immediately after the device was detached from the delivery cable, the occluder dislodged to the pulmonary artery side without causing a blockage.The device was removed from the patient percutaneously using a snare catheter (goose neck), which took approximately 30 minutes.After the device was successfully removed, the implant procedure was abandoned and there was no replacement device.The treatment for the patient will be reconsidered on a later date.There were no adverse health consequences to the patient.The patient remained hemodynamically stable throughout the procedure.According to the physician, the device was chosen appropriately based on morphological evaluation of the pda based on computerized tomography (ct) and angiography imaging, therefore the device dislodgement was related to the procedure and the patient's anatomy.No allegation to the sizing of the device was reported.No additional information was provided.
