Abstract

Aortic dissection is a serious condition in which there is a tear in the wall of the major artery carrying blood out of the heart (aorta). The extremely high mortality rate from dissection of the ascending aorta calls for rapidity of diagnosis; (>50% of patients die in 15 minutes). Death often occurs within 1–6 hours of onset of symptoms. With dissection of the descending aorta, 2–12 hours is available for diagnostic workup. Diagnostic testing includes assess the electrocardiogram (ECG), obtain immediate estimation of hemoglobin, serum creatinine and potassium, and assess the chest X-ray. Transthoracic echocardiogram (TTE) can be done rapidly, but TEE is most useful.
