RÉSUMÉ
We report a case of a patient that presented with typical angina pain and associated risk factors for coronary artery disease (CAD). Subsequent cardiac catheterisation led to the discovery of an isolated R-IIP modified Lipton classification coronary artery anomaly with follow-up coronary computed tomography angiography (CCTA) confirmation. This case report includes images of the CCTA and left heart catheterisation results, along with a discussion of the potential for increased risk of atherosclerosis in our patient, and a proposed explanation of his presentation with prototypical angina pain, despite lack of apparent atherosclerosis.
RÉSUMÉ
Coronary subclavian steal syndrome (CSSS) is a complication of coronary artery bypass graft surgery with the left internal mammary artery that results from left subclavian artery stenosis. A reversal of flow in the left internal mammary artery results in ischemia of the heart. We present the case of a 54-year-old man with CSSS with the rare symptom of dizziness. This indicates a potential component of undiagnosed vertebral steal syndrome as well.
