Multivessel Spontaneous Coronary Artery Dissection in the Setting of Anomalous Left Coronary Arteries.

UNLABELLED

Spontaneous coronary artery dissection (SCAD) is an epicardial coronary artery dissection not associated with atherosclerosis or trauma, and is not iatrogenic. The pathogenesis of SCAD is not fully understood, and the association of coronary artery anomalies and SCAD is not known. We present a case of a 64-year-old woman presenting with non-ST-elevation myocardial infarction (NSTEMI) due to have multivessel SCAD in the setting of anomalous origin of the coronary arteries with all three coronary arteries - right coronary artery (RCA), left anterior descending artery (LAD), and left circumflex artery (LCx) originating from the right sinus of Valsalva.

LEARNING POINTS

Spontaneous coronary artery dissection (SCAD) and coronary artery anomaly can arise where all three arteries originate from the right coronary cusp;There are possible associations between SCAD and coronary artery anomalies;Treatment and management of multivessel SCAD with a coronary artery anomaly where all three arteries arise from the right sinus of Valsalva.
