A case of a single coronary artery originating from left coronary sinus of Valsalva associated with serious coronary artery disease/Ciddi koroner arter hastaligi olan sol koroner sinus Valsalva'dan cikan tek koroner arter olgusu.A 77-year-old woman with history of hypertension and hypercholesterolemia was admitted to our clinic because of chest pain at rest. There was no history of diabetes mellitus, smoking and experienced myocardial infarction. Her family history was not significant for coronary heart disease coronary heart disease: see coronary artery disease. coronary heart disease or ischemic heart disease Progressive reduction of blood supply to the heart muscle due to narrowing or blocking of a coronary artery (see atherosclerosis). . The physical examination was normal, blood pressure was 160/90 mmHg, and heart rate was 60 bpm. Electrocardiogram showed sinus rhythm, reduction in R wave height and abnormally tall T waves in leads V1-V4. There were minimal increases in CK-CK MB levels and Troponin I was positive on serial determinations. Transthoracic transthoracic /trans·tho·rac·ic/ (-thah-ras´ik) through the thoracic cavity or across the chest wall. trans·tho·rac·ic adj. Across or through the thoracic cavity or chest wall. echocardiogram revealed hypokinesis of the apical-mid segment of interventricular septum with global left ventricular ejection fraction of 50%. Coronary angiography demonstrated a single coronary artery originating from the left sinus of Valsalva. The left main artery had a normal distribution; with the right coronary artery arising from the proximal left main artery. The left main artery courses anteriorly and supplies the left circumflex circumflex /cir·cum·flex/ (serk´um-fleks) curved like a bow. cir·cum·flex adj. 1. Curving or bending around. 2. Bowed. circumflex curved like a bow. and the left anterior descending artery. There was a significant stenosis in the proximal in the right coronary artery. There were two lesions (90% and 70% stenoses) in left anterior descending artery after a diagonal branch. There was a 90% stenosis in the left circumflex artery (Fig. 1, 2 and Video 1, 2. See corresponding video/movie images at www.anakarder.com). Aortography aortography /aor·tog·ra·phy/ (a?or-tog´rah-fe) radiography of the aorta after introduction into it of a contrast material. a·or·tog·ra·phy n. showed one coronary ostium ostium /os·ti·um/ (os´te-um) pl. os´tia [L.] an opening or orifice.os´tial ostium abdomina´le tu´bae uteri´nae in the left sinus of Valsalva and no ostium in the right sinus of Valsalva. The left ventriculography ventriculography /ven·tric·u·log·ra·phy/ (ven-trik?u-log´rah-fe) 1. radiography of the cerebral ventricles after introduction of air or other contrast medium. 2. displayed hypokinetic apex. The patient was decided to be surgically treated. But she did not accept operation, so we applied medical therapy and risk factor modification. [FIGURES 1-2 OMITTED] A single coronary artery is a rare congenital anomaly with an incidence of 0.02-0.04%. We aimed to introduce a case of a single coronary artery, associated with old age and serious coronary artery disease coronary artery disease, condition that results when the coronary arteries are narrowed or occluded, most commonly by atherosclerotic deposits of fibrous and fatty tissue. .
