A rare case of simultaneous spontaneous coronary artery dissections in the circumflex and the right coronary arteries presenting as acute myocardial infarction: a case report.

Simultaneous Spontaneous Coronary Artery Dissection (SCAD) involving multiple coronary arteries is an exceptionally rare occurrence. We present a unique case of a 55-year-old woman with no known cardiovascular risk factors who presented with severe chest pain and ST-segment elevation myocardial infarction (STEMI). Coronary angiography revealed simultaneous SCAD in both the Right Coronary Artery (RCA) and the Circumflex (Cx) artery, an unprecedented finding. The patient underwent percutaneous coronary intervention (PCI) for the RCA and received medical therapy for the Cx artery. The three-month follow-up demonstrated the disappearance of SCAD in the Cx artery and patent stents in the RCA, indicating positive patient outcomes. This case highlights the complexity of SCAD and the importance of individualized treatment strategies.
