RT Journal Article SR Electronic T1 Single coronary artery arising from the left sinus of valsalva JF Saudi Medical Journal JO Saudi Med J FD Prince Sultan Military Medical City SP 1537 OP 1540 VO 23 IS 12 A1 Ayfer Mavi A1 Alper Sercelik A1 Resat Ayalp A1 Erdem Gumusburun A1 Talantbek Batyraliev YR 2002 UL http://smj.org.sa/content/23/12/1537.abstract AB A single coronary artery is a rare congenital anomaly of the coronary arteries where only one coronary artery arises from the aortic trunk by a single coronary ostium, supplying the entire heart. We report a case of a 57-year-old woman with atypical chest pain, in whom coronary angiography showed a L-I subtype single coronary artery (arising from a single ostium in the left sinus of valsalva) without associated cardiovascular disease. The clinical significance and subtype of the single coronary artery are discussed.
