Percutaneous closure of secundum atrial septal defects with the amplatzer occluder: Early clinical experience and echocardiographic follow-up

Objective :The purpose of this research is to explore the clinical application prospect of percutaneous closure atrial septal defects guided by thoracic echocardiography. Methods : Selected 90 inpatients who were pure atrial septal defects from sep 2014 to December 2019, Under local anesthesia via femoral vein puncture closure atrial septal defects guided by thoracic echocardiography, Real-time evaluatie plugging result.The patients underwent follow-up echocardiography at 3 days, 3 months, 6 months, 12 months after surgery．Results Intraoperative occlusion was not successful in 3 cases（The plug is not fixed firmly, so withdraw the plug）， Occluder were successfully implanted in 87 patients, there were no serious complications such as valvular injury、pericardial effusion、occluder off,five patients had a little residual shunt in 3 days after surgery, residual shunt disapper after 3 months underwent follow-up echocardiography, the rest of the patients does not appear residual shunt.. Conclusion :Percutaneous closure atrial septal defects guided by thoracic echocardiography had Superiority such as simplicity of operator、shorter operator time、less-injury、safety、fast recovery,the surgery has a broad clinic prospects．

Objectives: This study aimed to review the experience with percutaneous closure of ventricular septal defects (VSDs) at the National Heart Center (NHC) in Muscat, Oman. Methods: This retrospective study was conducted from November 2008 to December 2017. Patients’ electronic medical records were reviewed to identify their clinical, imaging and interventional data before and after the procedure and on the last followup. Results: A total of 116 patients, the majority of which were female (58%), underwent 118 percutaneous procedures for VSD closure at a median age of 3.54 years (range: 0.25–33 years) and a median weight of 12 kg (range: 3.5–78 kg). The mean diameter of the VSDs as determined by transoesophageal echocardiogram was 5.6 ± 1.9 mm (n = 105). The commonest type of VSD was perimembranous (n = 75, 63.5%). Devices were successfully placed during 111 (94.1%) procedures in 109 (94.0%) patients, with the commonest device being a Amplatzer™ duct occluder I (St. Jude Medical, Little Canada, Minnesota, USA; n = 39, 35.1%). There was no mortality. Early major cardiac complications occurred in six patients (5.5%) with device embolisation being the commonest (n = 4, 3.7%). The median follow-up period was 19 months (range: 1–84 months) in 89 (81.7%) of the patients. One patient (0.9%) required a permanent pacemaker for a complete heart block. Conclusion: This study has demonstrated a good rate of VSD closure with low morbidity and no mortality using the percutaneous approach with different devices. Long-term follow-up is needed to specifically evaluate the function of adjacent structures and the long-term effects on conduction systems.
