Abstract
OBJECTIVE Secundum atrial septal defect (ASD) is a common congenital heart defect. There is limited data on both early and late atrioventricular (AV) block post ASD closure. The aim of this study was to determine the incidence and risk factors of AV block associated with ASD closure. METHODS A retrospective analysis of all patients who underwent ASD closure either with a device or surgical method at the Royal Children's Hospital Melbourne between 1996 and 2010 was performed. Baseline demographics, procedural details and follow-up data were collected from medical records. RESULTS A total of 378 patients were identified; 242 in the device group and 136 in the surgical group. Fourteen patients (3.7%) had AV block (1 with second degree and 13 with first degree) at a median follow-up of 28 months; 11/242 (4.5%) in the device group and 3/135 (2.2%) in the surgical group (p=0.39). Six patients had new-onset AV block after ASD closure. In the device subgroup, patients with AV block at follow-up had a larger indexed device size compared with those without (22 (15-31) vs 18(7-38), p=0.02). Multivariate analysis revealed the presence of AV block either pre procedure or post procedure to be the only variables associated with late AV block. CONCLUSIONS Late AV block in patients with repaired ASD is rare and most likely independent of the technique used. In the device subgroup, the only risk factor identified to be associated with late AV block was the presence of either preprocedural or postprocedural AV block, so long-term follow-up for these patients should be provided.

Abstract
BACKGROUND The safety and efficacy of percutaneous closure of atrial septal defects (ASDs) is determined by several variables, including defect size, presence of adequate rim tissue, relationship to other cardiac structures, and associated congenital anomalies. OBJECTIVE We sought to determine the accuracy of computed tomographic angiography (CTA) in predicting a defect's size compared with pre-procedural transesophageal echocardiography (TEE) and to the current "gold standard" balloon sizing by intracardiac echocardiography (ICE). METHODS Thirty-five consecutive patients referred for possible percutaneous closure of suspected secundum ASD were evaluated with gated multislice CTA after initial TEE screening. Axial and sagittal image planes of the ASD from the CTA multiplanar reformation (MPR) images were used to measure the defect size and surface area. RESULTS Of the 35 patients with secundum-type ASDs, 5 subjects had disqualifying anatomy by CTA and 2 had an unsuccessful closure, resulting in a procedural success rate of 93%. Measurement of defect area by gated MPR images provided the strongest correlate to ICE balloon size. In large ASDs, TEE was less well correlated to the maximum defect size and identification of the inferior/inferoposterior rims than CTA. CONCLUSIONS Cardiac CTA is an accurate and useful technique for pre-procedural assessment of ASDs and may be superior to conventional TEE in large defects that have deficient inferior rims.

Abstract
BACKGROUND Controversy still exists regarding closure of atrial septal defects (ASDs) in patients >40 years of age who are largely asymptomatic or do not have large shunts (LS). If left unrepaired, the majority of patients will experience symptoms and will have a shorter life span compared to patients who undergo repair. This study presents the outcomes of closure of ASDs in adults >40 years using the Amplatzer septal occluder. METHODS A total of 113 patients (79F/34M) with a mean age of 57.9 years (SD 11.9) who had indications for closure (right ventricular [RV] enlargement by echocardiograpy, clinically symptomatic) underwent an attempt of transcatheter closure. The mean size of ASD as measured by transesophageal echocardiography (TEE) (30 patients) or intracardiac echocardiography (83 patients) was 17.2 mm (SD 7.3) with mean Qp:Qs of 2.2:1 (SD 1.1). Follow-up at 24 hours, 6 month, and yearly thereafter included physical examination, TEE, and/or transthoracic echocardiography; furthermore, chart review (n = 112) as well as telephone interviews (n = 56) were conducted to determine clinical symptomatic status. RESULTS The procedure was successful in 112 patients and 1 patient failed due to the presence of a large defect (44 mm). One hundred four patients had a single device implanted, 7 had two, and 1 had three. Following the procedure, 96 patients had immediate complete closure (CC), 3 had trivial shunt (TS), 11 had small shunt (SS), and 2 had moderate shunt (MS). At 24 hours postprocedure, 100 patients had CC, 7 had TS, 3 had SS, 1 had MS, and 1 had LS. Four patients had complications: one had device migration within 24 hours, two had atrial arrhythmias (supraventricular tachycardia, atrial tachycardia), and one had large hematoma. At 6 months postprocedure, 100 patients had CC, 6 had TS, 5 had SS, and 1 had MS. At 6-month follow-up, the right ventricle end-diastolic dimension decreased from 35.3 mm (SD 7.6) preprocedure to 23.8 mm (SD 6.6) (P < 0.001) and the majority of patients reported improvement in their symptoms. CONCLUSIONS ASD closure is safe and effective in patients over 40 years of age with minimal complications. The procedure resulted in a decrease in the RV size that was accompanied by improvement in clinical symptoms. Our findings suggest that device closure of ASDs in adult patients >40 years of age should be the first option of management.

Abstract
BACKGROUND Transcatheter closure of a perimembranous ventricular septal defect (PmVSD) is usually performed with an asymmetric Amplatzer occluder, which is not an ideal device. Experience with the use of the Amplatzer muscular ventricular septal defect occluder (MVSO) to close selected PmVSDs is presented. SETTING Two tertiary referral centres for paediatric cardiology in two countries. OBJECTIVE To look at the safety and efficacy of the application of the MVSO in patients with appropriate PmVSD anatomy. PATIENTS AND INTERVENTION The procedure was performed in 10 patients aged 3.2-40 (mean 12.5) years. All had a PmVSD with a mean diameter of 5.4 (range 4-11) mm, with an extension towards the muscular septum. The mean distance of the defect from the aortic valve was 5.4 (range 4-6) mm. In all but one patient, the MVSO was introduced in routine antegrade transvenous fashion (4-mm device in one patient, 6-mm device in five, 8 mm in two, 10 mm in one, and 12 mm in one). In one patient, the device was deployed by retrograde implantation. RESULTS All procedures except one were performed without complications, and complete closure of the VSD was achieved. One patient with a residual shunt developed haemolysis, which resolved over 10 days. In three patients, trivial, non-progressive tricuspid regurgitation appeared after the procedure. No other complications were observed over 1.7 (range 0.2-3.5) years of follow-up. CONCLUSION Application of the MVSO for closure of selected PmVSDs seems to be a safe and effective treatment option.

Abstract
Little is known about the efficacy and safety of the 40 mm Amplatzer septal occluder (ASO). Thirty-three patients (22 female, 11 male) with a large secundum atrial septal defect (ASD) underwent attempted device closure using the 40 mm ASO at a median age of 40 years (range, 14-81 years) and median weight of 65 kg (range, 48-98 kg). The median size of the ASD measured on 2D transesophageal echocardiography (27 patients) or intracardiac echocardiography (6 patients) was 30.5 mm (range, 24-39 mm) and the median balloon-stretched diameter was 37.7 mm (range, 32-43.7 mm). The median Qp:Qs ratio was 3.2:1 (range, 1.4-6.2). The attempt was unsuccessful in five patients; two had device embolization and one had left atrial wall perforation due to the sheath; all three required emergent surgery. The attempt was successful in the 28 remaining patients, resulting in complete immediate closure in 14 and a trivial residual shunt in 14. Fluoroscopy time ranged from 8.6 to 37.8 min (median, 12.2 min). At 24-hr follow-up, 2D transthoracic echocardiography with color flow Doppler revealed complete closure in 23 patients, and 5 had a trivial residual shunt. There were no complications encountered in patients who received the device. On follow-up, all patients are doing well. We conclude that the 40 mm ASO is safe and effective in most patients with a large ASD up to a diameter of 39 mm. However, the use of this device requires careful attention as the procedure may be unsuccessful or the device may embolize.

Abstract
Using an Amplatzer membranous eccentric occluder, 186 patients with an average weight of 43.5 kg (range 12.5-77) underwent attempted catheter closure of a perimembranous venricular septal defect (PMVSD). Their age ranged from 3 to 51 years, with the an average age being 15.9 years. The patients were divided into three groups according to morphology of PMVSD: 106 patients with single PMVSD, 63 patients with single PMVSD with aneurysmatic formation, and 17 patients with multiple VSD with aneurysmatic formation. Using angiography, PMVSDs were measured to be between 2.5 and 12 mm, with an average of 5.1 mm. In the third group of patients, we did not measure the size of PMVSD and a device was selected according to the size of entry to the aneurysm. The device was successfully implanted in all patients. The immediate closure rate was 90% in the first group, increasing to 100% at 1 month and remained at that level during follow-up. The immediate closure rate in the second group was 98% and remained the same during follow-up. The immediate closure rate in the third group was 89% and during 1 year of follow-up remained the same. There was no clinical evidence of hemolysis and no incidence of device embolization or bacterial endocarditis after implantation. Before the procedure, all patients showed normal electrocardiogram (ECG) or left ventricle enlargement. After the procedure (at least 3 months later) ECG showed left anterior hemiblock (LAH) in nine patients, complete right bundle branch block in eight patients, and incomplete right bundle branch block in seven patients. A complete heart block (CHB) developed in 2 patients after the procedure (1.07%). The first patient developed LAH immediately after closure and CHB within 24 hours, The heart rate was 28 beats per minute. After treatment with steroids and atropine, CHB changed to sinus rhythm with LAH within 2 months. One year later, the ECG revealed the same findings. The second patient developed CHB immediately after the procedure and was on temporary pacing for 1 week. After 1 month, the patient recovered to sinus rhythm and ECG showed LAH.
