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.

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.
