During an atrial septal defect closure, the defect was balloon-sized to 26 mm and a 30 mm amplatzer septal occluder was chosen.The initial placement showed the defect to be mostly occluded, but a small residual was seen near the rupv rim.The eustachian valve seemed to be entrapped in the aso.After retrieval and repositioning the defect seemed closed, and the eustachian valve free, while still attached to the delivery cable.Once the aso was released, there again appeared to be entrapment of the eustachian valve and a residual defect.The aso subsequently embolized to the right ventricle.The case was aborted and the patient was sent to surgery for aso removal and defect repair with a double layer 4-0 prolene suture line.During explant of the aso, the atrial septum was noted to have a tear and several perforations which were also closed with a separate double layer 4-0 prolene suture line.The patient was transported to the cicu in stable condition.
