An anomalous left coronary artery detected by multislice computed tomography / Cok kesitli bilgisayarli tomografi ile tespit edilen bir sol koroner arter anomalisi.

A 57-year-old man was referred to the hospital with atypical chest pain and dyspnea. He had history of dyslipidemia for 10 years, smoking for 25 years and had hypertension for 5 years. He was on antihypertensive treatment. His electrocardiogram showed in sinus rhythm. His cardiovascular stress test was non-diagnostic, so we decided to perform a multislice computed tomography (MSCT). We performed MSCT (16 slice Aquillion) of coronary arteries using an electrocardiography gated standard protocol. An atypical left coronary artery (LCA) ostia originating from the right sinus of Valsalva was demonstrated just posterior to the right coronary ostia and its course was posterior to the aorta (Fig. 1). We could see the origin of both LCA and right coronary artery and proximal courses of them excellently. However, we could not see the distal course clearly. Therefore, we could not exclude obstructive coronary artery disease and decided to perform a coronary angiography. During the coronary angiography, we demonstrated the atypical origin of LCA and its course (Fig. 2, Video 1. See corresponding video/movie images at There were insignificant lesions in the right and left coronary systems.
