Early diagnosis is essential to mitigate the high mortality risk. Imaging modalities play a pivotal role in diagnosing aortic conditions, but determining the appropriate method can be challenging. Case description:\u00a0We report an asymptomatic 55-year-old female undergoing transthoracic echocardiography (TTE) for mitral and aortic valve regurgitation surveillance. Incidentally, a suspicious flow jet at the distal aortic arch was discovered, raising concerns of aortic dissection. A subsequent CT angiogram (CTA) identified this as an aortic ductus diverticulum at the aortic isthmus, not a dissection. Discussion:\u00a0Aortic dissection has a high initial 48-hour mortality, with even surgically managed cases exhibiting a 26% risk. Imaging tools such as a transoesophageal echocardiogram (TEE), CT and MRI scans are instrumental for diagnosis, with their applicability depending on the patient\u2019s clinical situation. The aortic ductus diverticulum, a developmental outpouching, often mimics other aortic pathologies, emphasising the importance of accurate imaging interpretation. Conclusion:\u00a0Aortic ductus diverticulum presents diagnostic challenges due to its resemblance to other aortic conditions. Advancements in imaging modalities improve diagnostic accuracy, but awareness and careful interpretation are paramount to ensure timely and appropriate patient care.<\/jats:p>","DOI":"10.12890\/2023_004183","type":"journal-article","created":{"date-parts":[[2023,11,30]],"date-time":"2023-11-30T05:16:51Z","timestamp":1701321411000},"source":"Crossref","is-referenced-by-count":0,"title":["Aortic ductus diverticulum mimicking aortic dissection: a case of diagnostic ambiguity in transthoracic echocardiography"],"prefix":"10.12890","volume":"11","author":[{"given":"Hazem","family":"Taifour","sequence":"first","affiliation":[{"name":"Rochester Regional Health\/Unity Hospital, Rochester, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fahad","family":"Eid","sequence":"first","affiliation":[{"name":"Rochester Regional Health\/Unity Hospital, Rochester, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mohamed","family":"Abu Sheikha","sequence":"first","affiliation":[{"name":"Rochester Regional Health\/Unity Hospital, Rochester, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ryan","family":"Hoefen","sequence":"first","affiliation":[{"name":"Rochester Regional Health\/Unity Hospital, Rochester, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"10397","published-online":{"date-parts":[[2023,11,29]]},"reference":[{"key":"10.12890\/2023_004183_ref1","doi-asserted-by":"crossref","unstructured":"<li>Shiga T, Wajima Z, Apfel CC, Inoue T, Ohe Y.
