Event or Problem Description
It was reported that on (b)(6) 2025, a 16mm amplatzer septal occluder was chosen for a atrial septal defect (asd) closure procedure using a 9f amplatzer torqvue delivery system.During procedure, a cobra-like deformation occurred on both disc surfaces while releasing the occluder with the steel cable, and it could not be restored.The customer reported that the device¿s flow-blocking membrane did not fully cover the defect, ultimately leading to the failure of the procedure.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.The patient remained hemodynamically stable throughout the procedure.There was no clinically significant delay in procedure and no adverse patient effects.The patient was reported stable.
