Asymptomatic presentation of type A aortic dissection with complete
right coronary artery avulsion: a case report.
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.
 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. 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.
