Nadir Bir Olgu: Non-koroner Sinüs Valsalvadan Köken Alan Sirkumfleks Koroner Arter

Koroner arter anomalileri çok sık görülmemelerine rağmen klinik olarak önemli yansımaları olabilmektedir. Koroner arter çıkış anomalileri, tüm koroner arter anomalilerinin önemli bir kısmını oluşturmaktadır. Burada miyokart perfüzyon sintigrafisinde inferiyor alanda iskemi görülen bir hastanın sirkumfleks arterinin non-koroner sinus valsalvadan çıkışı bahsedilmiştir. 44 yaşında erkek hasta efor ile gelen baskı tarzı göğüs ağrısı ile merkezimize başvurdu. Alınan anamnez, fizik muayene ve klinik testlerin miyokart perfüzyon sintigrafisi hariç hepsi normaldi. İnferiyor duvarda iskemi görülmesi üzerine koroner anjiyografi yapıldı. İşlem sonucunda sol sinüs valsalvadan çıkan sol ana koroner arterin devamı olması gereken sirkumfleks arter, nadir olarak görülen non-koroner sinüs valsalvadan çıktığı görüldü. Sonuç olarak kritik darlık olmayan fakat koroner çıkış anomalisi olan hastalarda iskemi meydana gelebilmektedir. Biz bu vakada olan iskemiyi, normalden daha uzun bir seyir gösteren koroner arterin distal yataklarının beslenmesinin ihtiyaç anında daha geç olmasına bağladık.

A Rare Case: Circumflex Artery Originating From Non-coronary Sinüs Valsalva

Although coronary artery abnormalities are not very common, they can have clinically significant impacts. Coronary artery outflow anomalies constitute an important part of all coronary artery anomalies. Here, we tried to present the exit of the circumflex artery from the non-coronary sinus valsalva of a patient with ischemia in the inferior area in myocardial perfusion scintigraphy. A 44-year-old male patient was admitted to our center with chest pain. Anamnesis, physical examination and clinical tests were normal, except for myocardial perfusion scintigraphy. Coronary angiography was performed after ischemia was observed on the inferior wall. As a result of the procedure, the circumflex artery, which should be a continuation of the left main coronary artery coming out of the left sinus Valsalva, emerged from the rare non-coronary sinus Valsalva. As a result, ischemia can occur in patients without critical stenosis, but with an anomaly of coronary output. We attributed ischemia in this case to the fact that the feeding of the distal beds of the coronary artery, which has a longer course than normal, was later at the time of need.
