Background: To compare the clinical outcomes of three surgical approaches for treating adult atrial septal defects (ASD): Thoracoscopic-assisted right vertical infra-axillary thoracotomy (TARVIAT) under central cardiopulmonary bypass (CPB), totally thoracoscopic (TT), and median sternotomy (MS) approaches, and to assess the feasibility and safety of the TARIAVT approach. Methods: This study reviewed 62 cases patients of repairing atrial septal defects via a TARVIAT and central extracorporeal circulation from 2019 to 2023. The patients included 22 males, aged between 18 and 59 years, with a mean age of 33.35 ± 10.97 years. The surgical indications were adult patients with moderate to severe tricuspid regurgitation and who were unsuitable for interventional closure of atrial septal defects. Exclusion criteria included patients diagnosed with severe pulmonary hypertension or Eisenmenger syndrome. Additionally, 67 patients who underwent TT approach repair of ASD and 72 patients who underwent MS approach repair of ASD were selected as the control groups. Operative time, CPB time, aortic clamping time, postoperative Intensive care unit (ICU) stay, postoperative mechanical ventilation time, 24-hour postoperative chest drainage, incision length, postoperative hospital stay, hospital costs, and postoperative complications were compared to assess statistical differences. Results: There were no deaths or major complications observed in any of the three groups. Statistically significant differences were found among the three groups in terms of extracorporeal circulation time, aortic clamping time, surgical time, 24-hour postoperative chest drainage, postoperative mechanical ventilation time, postoperative ICU stay, incision length, and postoperative hospital stay (p < 0.05). The TT group exhibited longer CPB and aortic clamping times compared to the TARVIAT and MS groups, while demonstrating lower 24-hour postoperative chest drainage volumes compared to the TARIAVT and MS groups. Both the TARVIAT and TT groups showed shorter surgical times, postoperative mechanical ventilation times, postoperative ICU stay, incision lengths, and postoperative hospital. However, there were no statistically significant differences among the three groups regarding hospital costs, postoperative left ventricular ejection fraction (LVEF) values, and the incidence of postoperative complications (p > 0.05). Conclusions: TARVIAT under central CPB is feasible and safe for adult patients. This approach presents lower invasiveness, shorter operative duration, and faster recovery compared to other methods. In conclusion, the TARVIAT approach for repairing adult ASD is both safe and effective, offering a viable surgical option for this condition.
