Methods: Data were collected from infants who underwent ventricular septal defect (VSD) repair or VSD and atrial septal defect (ASD) between March 2020 and September 2024. Based on propensity score matching, 80 small infants (weight &lt;5 kg and age &lt;6 months) were selected, of which 40 underwent VSD repair or VSD, and ASD repair through an RSAT, while 40 underwent VSD repair or VSD and ASD repair through a standard median sternotomy (SMS). Perioperative respiratory parameters, morbidity, and mortality were compared to assess the influence of the RSAT approach on pulmonary function and postoperative outcomes in small infants. Results: Primary outcome: there were no significant differences (p &gt; 0.05) in the perioperative oxygenation index and alveolar\u2013arterial oxygen gradient between the two surgical approaches. No significant differences were also observed between the two groups in the other respiratory parameters, including peak airway pressure, partial pressure of oxygen, and partial pressure of carbon dioxide. The operating time (150 \u00b1 20 min vs. 163 \u00b1 28 min; p &lt; 0.05) was shorter in the RSAT group compared to the SMS group. There were no deaths in either group. The complication rate was low in both groups, with no significant difference between the groups (p &gt; 0.05). Conclusion: Compared with SMS, the RSAT approach for the repair of congenital heart defects does not increase the risk of postoperative respiratory insufficiency and yields comparable outcomes in low-weight small infants.<\/jats:p>","DOI":"10.31083\/rcm46570","type":"journal-article","created":{"date-parts":[[2026,7,27]],"date-time":"2026-07-27T01:28:22Z","timestamp":1785115702000},"source":"Crossref","is-referenced-by-count":0,"title":["The Influence of Congenital Heart Defect Repair Through a Right Subaxillary Thoracotomy on Postoperative Pulmonary Function and Prognosis in Small Infants"],"prefix":"10.31083","volume":"27","author":[{"ORCID":"https:\/\/orcid.org\/0009-0000-9047-4047","authenticated-orcid":true,"given":"Xiaonan","family":"Wang","sequence":"first","affiliation":[{"name":"Department of Anesthesiology, Beijing Anzhen Hospital, Capital Medical University, Beijing Institute of Heart, Lung and Blood Vessel Diseases, 100029 Beijing, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiang","family":"Li","sequence":"additional","affiliation":[{"name":"Department of Anesthesiology, Beijing Anzhen Hospital, Capital Medical University, Beijing Institute of Heart, Lung and Blood Vessel Diseases, 100029 Beijing, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chen","family":"He","sequence":"additional","affiliation":[{"name":"Department of Anesthesiology, Beijing Anzhen Hospital, Capital Medical University, Beijing Institute of Heart, Lung and Blood Vessel Diseases, 100029 Beijing, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Huixian","family":"Li","sequence":"additional","affiliation":[{"name":"Department of Anesthesiology, The First Hospital of Tsinghua University, 100016 Beijing, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sheng","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Anesthesiology, Beijing Anzhen Hospital, Capital Medical University, Beijing Institute of Heart, Lung and Blood Vessel Diseases, 100029 Beijing, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"16242","published-online":{"date-parts":[[2026,5,25]]},"reference":[{"key":"ref1","doi-asserted-by":"crossref","unstructured":"Healy F, Hanna BD, Zinman R.
