What is SCAD?
SCAD is a separation of layers of the coronary artery wall, resulting in intramural haemorrhage and haematoma formation. Coronary insufficiency results due to the narrowing of the coronary artery lumen, from an expanding intramural hameatoma. SCAD may or may not involve an intimal layer tear.
