CTICasesSpontaneous Coronary Artery Dissection (SCAD)

Imaging findings
A coronary CTA shows no conventional atherosclerotic disease but reveals a faint intimal line in the left main coronary artery extending into the LAD, indicative of a dissection, with more distal partial occlusion. A dissection extending into the circumflex was also reported on angiogram.
Key takeaways
Spontaneous coronary artery dissection (SCAD) most commonly affects women in their last trimester of pregnancy or postpartum, and also heavy weightlifters. It often involves the left main and LAD, carrying a poor prognosis. Management can be supportive, as some dissections resolve spontaneously, and stenting can be challenging.
