Event or Problem Description
It was reported that on (b)(6) 2025, a 18mm amplatzer septal occluder was chosen for implant using a 9f amplatzer trevisio intravascular delivery system.During procedure, the loading was perfect but, when the left atrial disc was deployed, it emerged to a cobra shape.The occluder did not touch any adjacent cavities.The device was retrieved, and upon removing it from the operating table, it appeared as cobra.The deformed device was never released from the delivery cable while inside the patient.There was no report of any interaction with cardiac structures during deployment and no report of any angulation/kink noticed with the delivery system.A new 18mm amplatzer septal occluder was chosen and completed the procedure successfully.The patient remained hemodynamically stable throughout the procedure.There was no clinically significant delay in procedure and no adverse patient effects.The patient did not suffer any adverse event and reported stable.
Additional Manufacturer Narrative
