摘要

A 58-year-old man with hypercholesterolaemia was admitted for acute coronary syndrome with ST-segment elevation in inferior ECG derivations and ST-segment depression in antero-lateral ECG derivations (Panel A). The patient underwent emergency coronary catheterization. Subtotal occlusion of the third segment of the right coronary artery (RCA) (Supplementary data online, Movie S1) was successfully treated by stenting. No ostium for the left coronary artery (LCA) was found. Interestingly, the left ascending (LAD) and left circumflex arteries (LCX) angiograms were obtained through RCA opacification. Retrospective ECG-gated 256 detector-row coronary CT angiography (Philips ICT, Cleveland, USA, radiation dose: 14 mSv) demonstrated no LCA originating from the left sinus of Valsalva (LS) but a dominant RCA arising from the right sinus (Panel 8). A large right marginal artery (RM)
