Key result
Cardiac computed tomography angiography (cCTA) served as a valuable adjunct to coronary angiography in diagnosing spontaneous coronary artery dissection in three young women presenting with STEMI.
Why the study?
Spontaneous coronary artery dissection is an important cause of acute coronary syndrome in young women, but it may be missed by coronary angiogram alone.
Does cardiac computed tomography angiography (cCTA) improve the diagnosis of spontaneous coronary artery dissection (SCAD) in patients where coronary angiogram is inconclusive?

Does cardiac computed tomography angiography (cCTA) improve the diagnosis of spontaneous coronary artery dissection (SCAD) in patients where coronary angiogram is inconclusive?
cCTA serves as a valuable adjunctive imaging modality to coronary angiography for accurately diagnosing spontaneous coronary artery dissection, especially when initial angiographic findings are inconclusive.
Supports cCTA when angiography is inconclusive in suspected SCAD; leaves open prospective validation before practice change.
Spontaneous coronary artery dissection (SCAD) is an important cause of acute coronary syndrome particularly among young women. Although coronary angiogram (CAG) is the gold standard exam for the diagnosis, SCAD may be missed by CAG alone. Our case series illustrates the adjunctive role of cardiac computed tomography angiography (cCTA) to CAG in ascertaining the diagnosis of SCAD. Three young women were admitted with ST-segment elevation myocardial infarction. CAG showed no significant coronary artery stenosis. In two patients, cCTA performed after CAG revealed an intramural hematoma compressing the coronary lumen. In one patient, SCAD was initially misdiagnosed as Takotsubo cardiomyopathy and cCTA performed 1 month later allowed to make the correct diagnosis of SCAD assessing the spontaneous healing of the dissected vessel.

Capretti et al. (2019) conducted a case report in Spontaneous coronary artery dissection (SCAD) (n=3). Cardiac computed tomography angiography (cCTA) vs. Coronary angiogram (CAG) alone was evaluated on Diagnosis of SCAD. Cardiac computed tomography angiography (cCTA) served as a valuable adjunct to coronary angiography in diagnosing spontaneous coronary artery dissection in three young women presenting with STEMI.
