Koroner arter anomalileri, koroner anjiyografi yap�lan hastalar�n %0.3-1.3'�nde, otopsi incelemelerinde ise %1'inde saptanmaktad�r. Sol ana koroner arterin sa� sin�s valsalvadan ��k�� nadir bir durum olup, t�m koroner arter anomalilerinin %1-3'�n� olu�turmaktad�r. Bu olguda, sa� koroner sin�ste tek ostiumdan kaynaklanan sol ana koroner arterin varl�� ve literat�r incelemesi sunulmaktad�r. K�rk yedi ya��nda erkek hasta, g��s a�r�s� ve �arp�nt� �ikayetleriyle ba�vurdu. Eforla ortaya ��kan �ikayetleri son g�nlerde artm��t�. Bilgisayarl� tomografi (BT) anjiyografi sonucu, sa� koroner sin�ste tek ostiumdan ��kan koroner arterin k�sa bir seyir sonras� bifurkasyon g�stererek iki dala ayr�ld�� ve sol ana koroner arterin pulmoner trunkusun �n�nden ge�ti�i tespit edildi. Koroner arter anomalileri genellikle belirti vermez ve koroner anjiyografi s�ras�nda rastlant�sal olarak saptan�r. Sol ana koroner arterin sa� sin�s valsalvadan ��k�� nadirdir. Bizim olgumuzda, sa� koroner sin�sten ��kan tek ostiumdan kaynaklanan koroner arter k�sa bir seyir sonras� iki dala ayr�lmaktad�r. Bu t�r anomalilerin do�ru tan�s� i�in BT anjiyografi kullan�lmal�d�r.

Coronary artery anomalies are detected in 0.3-1.3% of patients undergoing angiography and in 1% of autopsy examinations. The origin of the left main coronary artery from the right coronary sinus is a rare condition, accounting for 1-3% of all coronary artery anomalies. This case presents the presence of a left main coronary artery originating from a single ostium in the right coronary sinus and a review of the literature. A 47-year-old male patient presented with chest pain and palpitations. His symptoms, which appeared with exertion, had worsened in recent days. Computed tomography (CT) angiography revealed that a single coronary artery originating from a single ostium in the right coronary sinus bifurcated into two branches after a short course, and the left main coronary artery passed in front of the pulmonary trunk. Coronary artery anomalies usually do not present symptoms and are often incidentally detected during coronary angiography. The origin of the left main coronary artery from the right coronary sinus is rare. In our case, the coronary artery originating from a single ostium in the right coronary sinus bifurcated into two branches after a short course. CT angiography should be used for the accurate diagnosis of such anomalies.
