Spontaneous coronary artery dissection (SCAD) was diagnosed using optical coherence tomography (OCT) in a patient with acute coronary syndrome. OCT revealed detailed subjacent disease and guidewire malposition, crucial for guiding intervention.
Area of Science:
- Cardiovascular Imaging
- Interventional Cardiology
- Coronary Artery Disease
Background:
- Acute coronary syndrome (ACS) necessitates accurate diagnosis and treatment.
- Spontaneous coronary artery dissection (SCAD) is an underdiagnosed cause of ACS.
- Coronary angiography is the standard diagnostic tool, but may underestimate SCAD severity.
Observation:
- A 42-year-old woman presented with ACS.
- Coronary angiography showed left anterior descending artery narrowing.
- Optical coherence tomography (OCT) confirmed SCAD and identified intramural hematoma, true lumen compromise, and false lumen flow.
Findings:
- OCT provided detailed insights into SCAD morphology beyond angiography.
- Active flow within the false lumen was observed.
- Distal guidewire displacement from the true to the false lumen was detected.
Implications:
- OCT enhances the understanding of SCAD pathophysiology.
- Accurate SCAD characterization by OCT is vital for interventional planning.
- Identifying guidewire position is critical for successful percutaneous coronary intervention in SCAD.

Computed Tomography
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
