[A case of a single coronary artery in the presence of coexistent atherosclerotic coronary artery disease].
A 57-year-old female was admitted with 6-month history of effort angina. Ascending aortography showed that the right coronary artery (RCA) did not originate from the right coronary sinus. Coronary arteriography showed that the circumflex branch (CX) continued beyond the crux into the right atrioventricular groove to supply marginal branches to the right ventricle, that is, RCA originated from the CX at the crux. RCA had the 75% stenosis near the crux. Left anterior descending branch (LAD) also had 90% stenosis at segment 6. She did not have the additional congenital cardiac anomalies, and underwent coronary artery bypass grafting to LAD and RCA without problem.
