Insights
Spontaneous coronary artery dissection (SCAD) is rare in males but can cause myocardial infarction. Intracoronary imaging is crucial for diagnosing SCAD, which may otherwise be missed on standard angiography.
Area of Science:
- Cardiology
- Vascular Medicine
- Medical Case Reports
Background:
- Spontaneous coronary artery dissection (SCAD) predominantly affects females.
- SCAD has diverse precipitating factors including exercise, trauma, pregnancy, drugs, and connective tissue diseases.
- Poor prognosis is associated with left main stem, left anterior descending (LAD) artery, and multivessel involvement, particularly in females.
Abstract:
BACKGROUND Spontaneous coronary artery dissection (SCAD) is primarily found in females. SCAD can have many precipitating factors such as exercise, trauma, pregnancy, drugs, and connective tissue disease. Prognosis is poor for left main stem, left anterior descending (LAD) artery, and multivessel involvement, especially for females. CASE REPORT We present a case of young African American male with sickle cell disease who presented with chest pain associated with shortness of breath. He was found to have non-ST elevation myocardial infarction (NSTEMI). He was diagnosed with SCAD during catheterization with the help of intravascular ultrasound imaging. Three drug-eluting stents were placed to cover the proximal LAD vessel along its whole length until resolution of the lesion. The patients' hospital course was complicated by an additional finding of left ventricular thrombus, possibly a complication of NSTEMI, which was treated with anticoagulation to complete resolution. CONCLUSIONS SCAD is fatal, it can proceed to cause myocardial infarction as in this particular patient's case, and sudden death if not recognized early. It can be missed on angiography alone; further intracoronary imaging such as intravascular ultrasound and optical computed tomography should be used to confirm the diagnosis of SCAD so that early and appropriate treatment can ensue.

Coronary Circulation
Coronary circulation begins at the base of the aorta, where two main arteries arise—the left and right coronary arteries. These arteries encircle the heart in the coronary sulcus and supply the...
