Acute aortic dissection occurs in 0.5–2.95 cases per 100,000 citizens-year. Although the modern diagnostic tools help in
more accurate diagnosis, the missleading findings still occure. We present a case of a 72-year-old man who was admitted to
cardiology ward due to persistent chest pain. Initial diagnosis of acute coronary syndrome was confirmed by electrocardiography
(ST segment depression in V1–V5 leads), transthoracic echocardiography (anterior wall dyskinesis) and laboratory tests
(Tn-I: 6.92 μ/L, CK-MB: 226.24 ng/mL). Due to aortic aneurysm history, computer tomography (CT) was performed. Neither
CT nor transthoracic echocardiography were negative for aortic dissection. Intraoperatively aortic dissection limited to Valsalva
sinuses was found. Left main orifice was blindly closed followed by Bentall procedure and coronary artery revascularisation.Acute aortic dissection occurs in 0.5–2.95 cases per 100,000 citizens-year. Although the modern diagnostic tools help in
