Abstract It is not uncommon to have prolapse of the atrial septal occluder device despite accurate measurement of atrial septal defect and an appropriately chosen device. This is particularly a problem in cases with large atrial septal defect with absent aortic rim. Various techniques have been described for successful implantation of atrial septal occluder in such a scenario. The essence of all these techniques is to prevent prolapse of the left atrial disc through the defect while the right atrial disc is being deployed. In this brief report, we illustrate the use of cobra head deformity of the device to successfully deploy the device across the atrial septum.

Cobrahead deformity is a known (but uncommon) phenomenon associated with the left atrial disc of the Amplatzer or Occlutech Figulla septal occluder device during percutaneous transcatheter atrial septal defect closure. It has also been postulated that the right atrial disc of the Amplatzer septal occluder device might upon occasion exhibit the cobrahead malformation. To date, only one case report concerning the cobrahead deformity in the right atrial disc of an Amplatzer septal occluder has been published, if we discount a report published as a letter to the manufacturer. Here we present the first report (known to us) of a cobrahead deformity in the right atrial disc of an Occlutech Figulla Flex II atrial septal defect occluder device during transcatheter closure of a complex atrial septal defect.

AbstractDevice closure of oval fossa atrial scptal defects with the Amplatzer Septal Occluder was performed in 26 patients ranging in age from 0.89 to 60.44 years. In eight additional patients no device implant was performed because of the presence of multiple defects or because the defect was of a size unsuitable for closure with the devices currently available. The strectched diameter of the defects that were closed ranged from 4 to 23 mm (mean 14±5.4 mm) and device sizes ranged from 4 to 24 mm. Two devices were unstable, of which one embolized to the right atrium after release. Both devices were retrived at the same procedure. One of these parients subsequently underwent a successful device closure of his defect using a larger (24-mm) device. Three patients had multiple defects, which were successfully closed with a single device. At 1-month follow-up 23/26 (88%) and at 3-month follow-up 22/24 (92%) patients had complete closure of their defects, while two had residual shunts. One further patient who had complete closure of his defect at 1-month post-implant had his device removed and his atrial septal defect patched surgically 8 weeks after device closure. This was done as a result of the development of a vegetation affecting the device after an episode of septicaemia, which was not relate to the cardiac problems. There was no procedure-related morbidty or martality and all patients remain well at the present time.

Background: Although various synthetic materials and pericardium have been used for atrial septal defect (ASD) closure, investigators are continuing to search for an ideal material for this procedure. We report and evaluate a case in which autologous right atrial wall tissue was used for ASD closure. Case: In this case, we closed a secundum ASD of a 22-year-old woman who also had right atrial enlargement due to the defect. After establishing standard bicaval cannulation and total cardiopulmonary bypass, we opened the right atrium with an oblique incision in a superior position to a standard incision. After examining the secundum ASD, we created a flap on the inferior rim of the atrial wall. A stay suture was stitched between the tip of the flap and the superior rim of the defect, and suturing was continued in a clockwise direction thereafter. Considering the size and shape of the defect, we incised the inferior attachment of the flap, and suturing was completed. Remnants of the flap on the inferior rim were resected, and the right atrium was closed in a similar fashion. Results: During an echocardiographic examination, neither a residual shunt nor perigraft thrombosis was seen on the interatrial septum. The patient was discharged with complete recovery. Conclusion: Autologous right atrial patch is an ideal material for ASD closure, especially in patients having a large right atrium. A complete coaptation was achieved because of the muscular nature of the right atrial tissue and its thickness, which is a closer match to the atrial septum than other materials.

AbstractWe report on a 37-year-old woman presenting with atrial arrhythmias after catheter closure of a secundum atrial septal defect with an Amplatzer septal occluder device. Eletrophysiological studies suggested that the arrhythmia originated from the left atrium, from an area near the device. Transseptal puncture was successfully performed under transoesophageal guidance and the arrhythmia was successfully ablated. This case showed that transseptal puncture can be safely performed in the presence of an Amplatzer septal occluder device under transoesophageal echocardiography guidance and we speculate that the device may have created the substrate for the arrhythmia.
