An Anomalous Right Coronary Artery with Interarterial Course Diagnosed by Multislice Computed Tomography

Öz

Coronary artery anomalies are potentially life-threatening anatomic variants that occur in approximately 1% of patients. Many of these anomalies are clinically benign; however, others are associated with serious morbidity. We describe the case of a patient in whom evaluation of angina pectoris revealed an anomalous right coronary artery arising from the left coronary sinus. At the coronary angiography the proximal segment of the right coronary artery was diffusely narrowed. Multislice computed tomography coronary angiography revealed a malignant anomalous right coronary artery.

İnterarteriyal Yerleşimli Sağ Koroner Arter Anomalisinin Çok Kesitli Bilgisayarlı Tomografi ile Tanısı

Öz

Koroner arter anomalileri hastaların yaklaşık %1'inde karşılaşılabilen ve hayatı tehdit eden anatomik varyantlardır. Bu anomalilerin büyük bir çoğunluğu benign olmasına rağmen bazıları anlamlı düzeyde morbiditeye sahiptir. Bu olguda sol koroner sinüsten köken alan sağ koroner arter anomalisi olan ve anjina pektorisi tarifl eyen bir hasta ele alındı. Olgumuzda koroner anjiyografi de sağ koroner arterin proksimal segmenti difüz olarak daralmıştı. Çok kesitli bilgisayarlı tomografi koroner anjiyografi de malignant sağ koroner arter anomalisi saptandı.
