Acute aortic dissection is the most challenging, life-threatening condition and requires prompt diagnosis and management. However about one-third of patients with type A acute aortic dissection (TAAAD) die within 24 hours, 50% within 48 hours and 95% die within first month. [1] Futhermore aortic dissection complicate with malperfusion syndrome is a devastating condition. Acute myocardial infarction within the TAAAD is the most fatal situation and occurs in about 1-2% of cases.[2] A total coronary artery avulsion is somewhat rare event in setting of TAAAD specially when it’s asymptomatic. the authors describe a case of a young man who underwent aortic root surgery and aortic arch replacemente for aortic type A dissectioc with complete right coronary artery avulsion completely asintomatic at presentation.
