In this study, a novel surgical technique using a pericardial autograft for aortic root repair was introduced. We described its surgical steps in detail and compare its clinical outcomes with direct suture technique.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Methods<\/jats:title>\n                <jats:p>Between July 2017 and August 2022, 95 patients with acute type A aortic dissection who underwent aortic root repair were enrolled, including aortic root repair using pericardial autograft (group A, <jats:italic>n<\/jats:italic>\u2009=\u200949) or direct suture (group B, <jats:italic>n<\/jats:italic>\u2009=\u200946). The patient\u2019s clinical data were retrospectively analyzed, and a 5-year follow-up was conducted.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>The 30-day mortality, re-exploration for bleeding, postoperative new-onset renal failure requiring continuous renal replacement therapy, stroke, and paraplegia occurred in 3%, 4%, 11%, 5%, and 2% of the overall patients, respectively. There was no significant difference in the 30-day mortality and complication rate between the two groups. The 30-day mortality and re-exploration for bleeding marked the primary endpoint events. Logistic regression analysis indicated that there was a significant correlation between the primary endpoint events and surgical technique (odds ratio, 0.002; 95% confidence interval, 0-0.159; <jats:italic>P<\/jats:italic>\u2009=\u20090.026). The aortic valve insufficiency of the two groups were significantly improved after operation (group A, <jats:italic>P<\/jats:italic>\u2009&lt;\u20090.001; group B, <jats:italic>P<\/jats:italic>\u2009&lt;\u20090.001). During follow-up, there was no significant difference in short-term survival between the two groups after surgery (log-rank <jats:italic>P<\/jats:italic>\u2009=\u20090.75), and all patients were free from reoperation for aortic disease.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusions<\/jats:title>\n                <jats:p>Patients who underwent aortic root repair using pericardial autograft tended to have reduced 30-day mortality and a lower risk of re-exploration for bleeding. Using pericardial autograft for aortic root repair is a safe and useful approach for patients with acute type A aortic dissection involving the aortic root.<\/jats:p>\n              <\/jats:sec>","DOI":"10.1186\/s13019-024-02909-2","type":"journal-article","created":{"date-parts":[[2024,6,26]],"date-time":"2024-06-26T06:02:37Z","timestamp":1719381757000},"update-policy":"http:\/\/dx.doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Clinical outcomes of aortic root repair using pericardial autograft for acute type a aortic dissection"],"prefix":"10.1186","volume":"19","author":[{"given":"Chuang","family":"Liu","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yao","family":"Wang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Peigang","family":"Ouyang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yangxue","family":"Sun","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lingchen","family":"Huang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiaogang","family":"Sun","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiangyang","family":"Qian","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Cuntao","family":"Yu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hongwei","family":"Guo","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2024,6,26]]},"reference":[{"key":"2909_CR1","doi-asserted-by":"publisher","unstructured":"Malaisrie SC, Szeto WY, Halas M, Girardi LN, Coselli JS, Sundt TM 3 et al. rd,. 2021 The American Association for Thoracic Surgery expert consensus document: Surgical treatment of acute type A aortic dissection.
