Spontaneous coronary artery dissection (SCAD) is characterized by a non-iatrogenic, nontraumatic separation of the coronary artery wall, contributing to acute coronary syndromes (ACS), and sudden cardiac death. SCAD predominantly affects the left anterior descending artery (LAD) and is frequently observed in middle-aged women. This condition has been associated with cancer treatment and exogenous hormones exposure. The diagnostic gold standard remains coronary angiography, management strategies include conservative measures, percutaneous coronary intervention (PCI), and coronary artery bypass graft surgery (CABG). We describe a case of a 54-year-old woman with breast cancer and a history of tamoxifen use, presenting with SCAD in the posterolateral branch (PLB) originating from the left circumflex artery (LCX), and right coronary artery (RCA) and managed conservatively.
