<p><b>Background:</b> For successful transcatheter closure of an atrial septal defect with the Amplatzer septal occluder, the shape of the defect should be considered before selecting the device size. The purpose of this study was to evaluate the results of transcatheter closure of an ovoid atrial septal defect.</p><p><b>Methods:</b> Between January 2010 and February 2012, cardiac computer tomography examinations were performed in 78 patients who subsequently underwent transcatheter closure of an atrial septal defect. In this retrospective study, we reviewed these patients' medical records. We defined an ovoid atrial septal defect as a value of 0.75 for the ratio of the shortest diameter of the defect to the longest diameter, as measured in a computed tomography image. Transthoracic echocardiography examinations were made at 1 day and 6 months after the procedure.</p><p><b>Results:</b> Transcatheter closure of an atrial septal defect was successful in 26 patients in the ovoid-defect group and in 52 patients in the round-defect group. There were no serious complications in either group, and the rate of complete closure at 6 months was 92.3% in the ovoid-defect group and 93.1% in the round-defect group (<i>P ></i> .05). The mean (SD) difference between the device size and the defect's longest diameter, and the mean ratio of the device size to the longest diameter were significantly smaller in the ovoid-defect group (1.7 � 2.9 versus 3.8 � 2.5 and 1.1 � 0.1 versus 1.3 � 0.2, respectively).</p><p><b>Conclusions:</b> Transcatheter closure of an atrial septal defect is indicated even for an ovoid atrial septal defect. Ovoid atrial septal defects can be closed successfully with smaller sizes of the Amplatzer septal occluder than for round atrial septal defects.</p>

AbstractPatients with atrial septal defect have an increased risk for atrial fibrillation. Increased P-wave dispersion predicts the development of atrial fibrillation. The aim of this study was to determine difference in P dispersion between transcatheter closure with Amplatzer septal occluder and surgical closure in childhood. A total of 68 children (the mean age was 7.2 plus or minus 3.3 years; the mean secundum atrial septal defects diameter was 17.3 plus or minus 5.4 millimetres) were evaluated in this study. Transcatheter closure was attempted in 41 children with secundum atrial septal defects, and the defect in 27 patients was closed by surgical techniques. P maximum, P minimum and P dispersion were measured by the 12-lead surface electrocardiography. P maximum, P minimum and P dispersion were found to be similar in patients with pre- and post-procedure (98.0 plus or minus 19.3 versus 95.1 plus or minus 23.0 milliseconds; 68.0 plus or minus 20.8 versus 67.6 plus or minus 24.3 milliseconds, 29.9 plus or minus 11.0 versus 27.1 plus or minus 12.1 milliseconds, respectively). There was no statistical significance in the comparison of P dispersion between the two groups. But in the surgical group, P-wave dispersion was decreased more significantly compared with baseline values (p-value equal to 0.03). In conclusion, there is no P dispersion between transcatheter closure with Amplatzer septal occluder and surgical closure of secundum atrial septal defect.

AbstractTo judge whether an Amplatzer™ Septal Occluder can be used as standard therapy instead of surgery for closure of atrial septal defects we report our experiences in 200 patients. Of these patients, 127 had an atrial septal defect with haemodynamically significant left-to-right shunt, 68 patients a persistent oval foramen after presumed paradoxical embolism, and 5 had a fenestration after Fontan-repair. Mean age was 29.8 years (0.8 to 77.7 years). Body weight ranged from 6.9 to 120.0 kg (mean 51.5 kg). After diagnostic cardiac catheterization, and balloon-sizing of the defect, we implanted Amplatzer™ Septal Occluders with stents of 4 to 28 mm diameter. Follow-up studies were obtained after 48hours, and one, six, and twelve months. Transcatheter closure of the atrial septal defect proved successful in all without any relevant residual shunts. In particular, complete closure was achieved in all patients after presumed paradoxical embolism. The mean period of follow-up is 9–5 months, with a range from 0.4 to 23.5 months, giving a total of 1898 patient months. The occlusion rate after three month was 98.1°. A trivial haemodynamically insignificant residual shunt remained in 1.9° of the patients. Fluoroscopy times ranged from 0 to 43.5 minutes, with a median of 8.7 minutes. The excellent results in the short and medium term in children and adults have resulted in using this device routinely at the present time for closure of central atrial septal defects up to a diameter of 28 mm. Final judgement, however, is only possible after long-term follow-up.

AbstractAimsTo assess results of closure of atrial septal defects within the oval fossa by devices delivered by catheterisation in symptomatic infants and children under 2 years of age.Methods and resultsThe Amplatzer septal occluder was used. Results, and complications of transcatheter device treatment in patients aged below 2 years were compared to previous results from our institution.PatientsWe attempted closure in 12 consecutive patients below the age of 2 years who presented with an atrial septal defect between May 1997 and 1999. Symptoms were failure to thrive in 6, frequent chest infections in 5, and the need for treatment of heart failure in the other. All were thought to have a defect suitable for interventional closure. The atrial defects were seen in isolation in 10 children, but 2 had associated pulmonary stenosis which had been treated by balloon dilation prior to placement of the Amplatzer occluder.ResultsThe Amplatzer septal occluder was implanted at a mean age of 1.4 ± 0.4, with a range from 0.8 to 1.8 years. Ratios of pulmonaryto-systemic flow had been 2.1 ± 0.5, with a range from 1.6 and 3.2, and the defect was measured at 12 ± 4 mms. Fluoroscopy time was 12.8 ± 10.2 minutes, with a range from 5 to 43 minutes, and the time of the overall procedure was 162 ± 70 minutes, with a range from 85 to 360 minutes. It proved necessary to remove the device in 2 patients (16%) because of a residual shunt and movement after release. One of these developed transient neurological complications. Both subsequently underwent surgical treatment.ConclusionSymptomatic patients less than 2 years of age can undergo successful closure of an atrial septal defect using the Amplatzer device, but the rates of success are less, and procedure time longer, than in older children or adults.

Abstract Ostium secundum atrial septal defects are mostly closed in the cardiac catheterization laboratories using either Amplatzer® (Abbott Laboratories, IL) atrial septal occluder, Gore® Cardioform septal occluder and more recently using the recently approved (US FDA approval June 2019) Gore® Cardioform atrial septal defect occluder (W. L. Gore & Associates, AZ). Similar to any new device in the market, there is a learning curve to the deployment of this device. We therefore aim to report the key features about this new Gore Cardioform atrial septal defect occluder device with special emphasis on technical aspects that can be employed during transcatheter closure of challenging ostium secundum atrial septal defects using this device.

First Case

AbstractClosure of atrial septal defects be means of intravenous catheterisation has been undertaken using a variety of devices as an alternative to surgical closure.1–5 We describe the first case, to the best of our knowledge, of infective endocarditis complicating a successful transcatheter closure. This highlights the potential risk of this procedure, and emphasises the need for appropriate antibiotic prophylaxis until complete endothelialization of the device has occurred.
