Abstract

Coronary artery anomalies have been mostly diagnosed incidentally in clinical practice. In this context, anomalous origin of the circumflex (Cx) artery has been relatively frequent compared with other anomalies. However, twin circumflex (Cx) arteries have been very rarely encountered to date. In a previous study, it was reported that the incidence of Cx arteries originating from the left and right coronary sinuses ranged from 0.19% to 0.29%. Clinically, this anomaly is generally considered a benign pathology. However, in the case of a possible acute coronary syndrome or unstable angina pectoris, it may cause difficulties in diagnosis and treatment. In this paper, we report a 58-year-old male patient admitted with angina pectoris in whom the coronary angiogram (CAG) demonstrated twin Cx arteries (two separate arteries stemming from the left and right coronary systems) along with a critical stenotic lesion in the right coronary artery (RCA).

Nadir Bir Koroner Arter Çıkış Anomalisi: İkiz Circumflex Arter

Abstract

Koroner arter anomalileri klinik pratikte çoğunlukla tesadüfen teşhis edilmektedir. Bu bağlamda sirkumfleks (Cx) arterin anormal orijini diğer anomalilere göre nispeten daha sık görülmektedir. Ancak bugüne kadar ikiz sirkumfleks (Cx) arterlere çok nadir rastlanmıştır. Daha önce yapılan bir çalışmada sol ve sağ koroner sinüslerden kaynaklanan Cx arterlerin görülme sıklığının %0.19 ile %0.29 arasında değiştiği bildirilmişti. Klinik olarak, bu anomali genellikle iyi huylu bir patoloji olarak kabul edilir. Ancak olası bir akut koroner sendrom veya kararsız angina pektoris durumunda tanı ve tedavide zorluklara neden olabilir. Bu yazıda, anjina pektoris ile başvuran ve koroner anjiyografide (KAG) ikiz Cx arterleri (sol ve sağ koroner sistemlerden çıkan iki ayrı arter) ile birlikte sağ koroner arterinde (RCA) kritik bir stenotik lezyon gösteren 58 yaşında bir erkek hasta sunuldu.
