Safety and efficacy of "one-stop" combining atrial septal defect and left atrial appendage closure
Objective:To investigate the effectiveness and safety of "one-stop" combining trial septal defect (ASD) and left atria appendage (LAA) closure(LAAC).Methods:Patients with atrial fibrillation (AF) combined with ASD who underwent one-stop surgery for LAAC combined with ASD occlusion at Zhongshan Hospital of Fudan University from June 2018 to September 2022 were retrospectively analyzed, and demographic data such as age and gender; intraoperative imaging data such as pulmonary artery pressure, LAA pressure, and ASD size of atrial septal defect were collected.And left atrial septal defect was followed up at 6 and 12 months after surgery echocardiographic information such as left atrial internal diameter (LAD), left ventricular end-diastolic diameter (LVEDD), left ventricular ejection fraction (LVEF), pulmonary artery systolic pressure (PASP), degree of tricuspid regurgitation (TR) and electrocardiogram (ECG) information were followed up at 6 months and 12 months after surgery. Postoperative complications such as blocker thrombosis, residual shunt at blocker, blocker malfunction, pericardial effusion and new arrhythmias were recorded.Results:A total of 32 patients [(68.2±9.3) years ], including 11 males (34.3%,11/32) were included in this study, and all patients successfully underwent a combined "one-stop" procedure for LAAC and ASD occlusion. Intraoperatively, the blocker was properly positioned and well fixed, and no complications such as residual shunt were found. One patient was found to have a minor residual shunt, and one patient developed novel right bundle branch block at the 6-month postoperative follow-up, but no adverse events were found at the 12-month postoperative follow-up.Conclusion:The combined "one-stop" procedure of LAA and ASD occlusion is safe and effective for patients with ASD combined with AF, with satisfactory follow-up results.
