Abstract BACKGROUND Transcatheter device closure of secundum atrial septal defect (ASD) with valvular pulmonary stenosis (PS) under fluoroscopy and/or transesophageal echocardiography (TEE) guidance is a mature technology. However, little study has focused on whether the technology can be guided totally by transthoracic echocardiography (TTE), even in children.METHODS Thirteen children with ASD combined with PS underwent transcatheter device closure totally guided by TTE at our cardiac center from March 2 016 to August 2 019. Percutaneous transcatheter pulmonary valvuloplasty was performed first and then transcatheter closure of the ASD uneventfully.RESULTS All cases were successfully treated with transcatheter balloon pulmonary valvuloplasty and closure of ASD respectively via femoral vein approach solely under TTE guidance. The mean defect size was 8.1±1.4 mm (range: 5.5-10 mm), the preoperative mean pressure gradient across pulmonary valve was 61.2±5.5 mmHg (range: 51-71 mmHg). The mean device size used was 11.1±1.9 mm (range: 8- 14 mm), the mean procedure time was 55.1±8.0 min (range: 45-71 min). There were no serious cardiovascular related complications. During the follow-up period (10 mon to 47mon), no arrhythmias device, thrombosis, residual fistulas or device frame fractures were detected. PS gradient had significant difference before and after procedure during the follow up (t=28.9, P =0.000).CONCLUSION Simultaneous transcatheter treatment for ASD complicated by PS in children under TTE guidance is an safe and effective therapeutic option.

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.

Background: Transcatheter device closure of ostium secundum atrial septal defect is a safe & effective intervention in older children, & is usually done under transesophageal echocardiography guidance. However, the procedure under transthoracic echocardiography guidance, especially in smaller children, is done only at few centers, the data of which is scarce. Methods: A prospective study was undertaken to assess the mid-term efficacy and outcome of transcatheter device closure of ostium secundum atrial septal defect  under transthoracic echocardiographic guidance, in children <15 Kg. Results: Eighty three children with ostium secundum atrial septal defect  were included in the study. Median age of the study population was 3.5 years (1.9-5.6 years), and median weight of 11.6 Kg (7.6 - 14.9 Kg). The primary and secondary procedural success rates were 94% and 96.4% respectively. Post procedure patients were followed up for 12-30 months. Device related major complications were encountered in 4 (4.8%) cases. The total occlusion rates of the defect at 24 hours, 1 month and 3 months post procedure were 94%, 98.8% and 100% respectively. Conclusion: The transcatheter device closure of ostium secundum atrial septal defect  under transthoracic echocardiography guidance, in children <15 Kg, has a high short and mid-term safety and efficacy.
