Abstract
A 52-year-old man presented to our cardiology service for an elective diagnostic coronary angiogram for risk stratification in the context of stable angina. He was diagnosed with antiphospholipid syndrome 2 years prior and had three known thrombotic episodes in the form of a stroke, retinal artery occlusion and deep vein thrombosis. Our initial differential was atherosclerotic coronary artery disease, however, coronary angiography demonstrated a dominant right coronary artery with a long segment of chronic spontaneous dissection distally but with thrombolysis in myocardial infarction III flow. He was treated medically with antianginals which rendered him asymptomatic and is currently on regular follow-up in the cardiology outpatient department.
