Key result
Optical coherence tomography confirmed spontaneous coronary artery dissection and revealed subjacent disease patterns imperceptible to angiography, including intramural hematoma and false lumen flow.
Why the study?
Does optical coherence tomography improve the evaluation of spontaneous coronary artery dissection compared to angiography alone?

Does optical coherence tomography improve the evaluation of spontaneous coronary artery dissection compared to angiography alone?
Optical coherence tomography provides detailed visualization of spontaneous coronary artery dissection features that are imperceptible on standard angiography, which can be critical for guiding intervention.
A 42-year-old woman underwent coronary angiography for acute coronary syndrome. It showed a progressive narrowing from the middle segment of the left anterior descending artery. Optical coherence tomography (OCT) confirmed the angiographic suspicion of spontaneous coronary dissection. OCT also revealed different patterns of subjacent disease, imperceptible to the angiography: areas of intramural hematoma with blood stasis, progressive compromise of the true lumen, and areas with active flow through the false lumen. It also detected the distal guidewire going out from the true to the false lumen, a feature of capital importance to lead an eventual coronary intervention.

Iglesias et al. (2011) conducted a case report in Spontaneous coronary artery dissection (n=1). Optical coherence tomography (OCT) was evaluated on OCT findings of spontaneous coronary dissection. Optical coherence tomography confirmed spontaneous coronary artery dissection and revealed subjacent disease patterns imperceptible to angiography, including intramural hematoma and false lumen flow.
