Key result
Aortic root surgery and aortic arch replacement were performed in a young man presenting asymptomatically with type A aortic dissection and complete right coronary artery avulsion.
Why the study?
Total coronary artery avulsion is a rare event in type A acute aortic dissection, especially when presenting asymptomatically.
Case Report (n=1)
Highlights a rare presentation of asymptomatic type A aortic dissection complicated by complete right coronary artery avulsion.
Raises awareness for silent type A dissection with RCA avulsion in young adults; leaves open need for larger series to guide recognition.
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.

Dralov et al. (2020) conducted a case report in Type A acute aortic dissection with complete right coronary artery avulsion (n=1). Aortic root surgery and aortic arch replacement was evaluated. Aortic root surgery and aortic arch replacement were performed in a young man presenting asymptomatically with type A aortic dissection and complete right coronary artery avulsion.
