This study aims to characterize the patient cohort, assess outcomes, and evaluate the role of preoperative diagnostics in these high-risk patients. Methods: Patients who underwent concomitant coronary artery bypass and acute type A aortic dissection repair between March 2007 and June 2023 were included. In-hospital survivors and non-survivors were compared. Logistic regression analyses were performed to identify predictors of in-hospital mortality. Preoperative computed tomography scans were independently reviewed by a cardiovascular radiologist to assess potential coronary involvement. The agreement between computed tomography and intraoperative reports of coronary dissection was evaluated using Cohen\u2019s \u03baappa test. Results: The cohort consisted of ninety-eight patients. In-hospital mortality was 26.5% (n = 26). The right coronary artery was the most frequently grafted (57%, n = 56). Elevated preoperative creatine kinase was the only predictor of in-hospital mortality (p = 0.044). Of the 72 available preoperative CT scans, 76% (n = 55) indicated coronary involvement, whereas intraoperative coronary dissection requiring bypass grafting was documented in only 42% (n = 30)). The agreement between computer tomography and intraoperative dissection reports was poor (\u03baappa 0.043 (95% CI, \u22120.155 to 0.241), p = 0.66). Conclusion: Simultaneous coronary artery bypass during acute type A aortic dissection repair remains associated with high mortality and morbidity. The right coronary artery is most often affected. Coronary bypass is not always linked to coronary dissection, making intraoperative detection challenging. This underscores the importance of preoperative diagnostics, especially computer tomography.<\/jats:p>","DOI":"10.3390\/jcdd12090336","type":"journal-article","created":{"date-parts":[[2025,9,2]],"date-time":"2025-09-02T13:01:13Z","timestamp":1756818073000},"page":"336","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Need for Coronary Artery Bypass Grafting in Acute Type A Aortic Dissection: Clinical Insights, Diagnostic Gaps, and Surgical Outcomes"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9529-7094","authenticated-orcid":false,"given":"Mohammed","family":"Morjan","sequence":"first","affiliation":[{"name":"Department of Cardiac Surgery, Medical Faculty, Heinrich Heine University, 40225 Dusseldorf, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Charlotte Philippa","family":"J\u00fcrgens","sequence":"additional","affiliation":[{"name":"Department of Cardiac Surgery, Medical Faculty, Heinrich Heine University, 40225 Dusseldorf, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2041-5823","authenticated-orcid":false,"given":"Tong","family":"Li","sequence":"additional","affiliation":[{"name":"Department of Cardiac Surgery, Medical Faculty, Heinrich Heine University, 40225 Dusseldorf, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0003-5536-7600","authenticated-orcid":false,"given":"Luis Jaime","family":"Vallejo Castano","sequence":"additional","affiliation":[{"name":"Department of Cardiac Surgery, Medical Faculty, Heinrich Heine University, 40225 Dusseldorf, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Freya","family":"Jenkins","sequence":"additional","affiliation":[{"name":"Department of Cardiac Surgery, Medical Faculty, Heinrich Heine University, 40225 Dusseldorf, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Amin","family":"Thwairan","sequence":"additional","affiliation":[{"name":"Department of Cardiac Surgery, Medical Faculty, Heinrich Heine University, 40225 Dusseldorf, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vivien","family":"Weyers","sequence":"additional","affiliation":[{"name":"Institute of Diagnostic and Interventional Radiology, Medical Faculty, Heinrich Heine University, 40225 D\u00fcsseldorf, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hannan","family":"Dalyanoglu","sequence":"additional","affiliation":[{"name":"Department of Cardiac Surgery, Medical Faculty, Heinrich Heine University, 40225 Dusseldorf, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sebastian Daniel","family":"Reinartz","sequence":"additional","affiliation":[{"name":"Institute of Diagnostic and Interventional Radiology, Medical Faculty, Heinrich Heine University, 40225 D\u00fcsseldorf, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8580-6369","authenticated-orcid":false,"given":"Artur","family":"Lichtenberg","sequence":"additional","affiliation":[{"name":"Department of Cardiac Surgery, Medical Faculty, Heinrich Heine University, 40225 Dusseldorf, Germany"},{"name":"Cardiovascular Research Institute D\u00fcsseldorf (CARID), Medical Faculty, Heinrich Heine University, 40225 D\u00fcsseldorf, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,9,2]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"350","DOI":"10.1016\/j.jacc.2015.05.029","article-title":"Presentation, Diagnosis, and Out-comes of Acute Aortic Dissection: 17-Year Trends from the International Registry of Acute Aortic Dissection","volume":"66","author":"Pape","year":"2015","journal-title":"J.
