A late complication with the cardioSEAL ASD occluder device and need for surgical revision

A late complication of the CardioSEAL atrial septal defect (ASD) occluder is reported. Although left atrial umbrella was completely epithelialized and occluded ASD without residual defect, the right atrial umbrella protruded toward the center of right atrium after 18 months. We believe this may be associated with the structural abnormality of the device. Cathet Cardiovasc Intervent 2001;54:335–338. © 2001 Wiley-Liss, Inc.
