Near-fatal acute dissection of the thoracic aorta involving the right coronary artery.

Aortic dissection is the most common acute disease involving the ascending aorta and carries a high mortality rate if surgical therapy is not initiated rapidly following the onset of symptoms. Therefore, timely recognition of this disease entity coupled with urgent and appropriate management is the key to a successful outcome. We describe a patient with aortic dissection extending into the right coronary artery (RCA) who was successfully resuscitated and operated on following a cardiac arrest during transfer to the operating room.
