Large device for large atrial septal defects-the 40 mm Atrial Septal Occluder.

The 40 mm ASO device can be used with a high rate of successful implantation for ASD closure The technique of implantation usually requires more than simple direct, device placement Balloon-assisted technique (BAT) can make use of this large occluder more predictable Experience contributes significantly to procedure success Important complications, such as device embolization will occur in a small number of cases Thrombotic complications are infrequent, even with aspirin monotherapy.
