Overview
The current gold standard for a SCAD diagnosis is coronary angiography as it is widely available and the first-line imaging modality for patients presenting with acute coronary syndrome. The predominant angiographic appearance of SCAD consists of smooth narrowing of varying severity and length secondary to compression of the true lumen and expansion of the false lumen by the development of intramural hematoma.
Angiography
Angiographic findings include:
- Type 1: appearance on an angiography involves the presence of two intraluminal streams/lumens separated by a radioluscent flap of intima.
- Type 2: when the dissection plane is deeper in the vessel wall between the media and adventitial layers, formation of a hematoma can result in luminal narrowing which is seen as a stenosis on an angiography.
- Type 3: appearance mimics atherosclerosis. The dissection is typically shorter than that of type 2 (< 20 mm) and may have a hazy appearance.
