Computed tomography of coronary artery anomaly : case report

Background: Anomalies of coronary vessels can be described as varies group of congenital heart disease, which can have different level of clinical manifestation and changeable pathophysiological mechanisms. Diagnosis and imaging of vessel course is essential before percutaneous angioplasty intervention and coronary artery bypass grafting as well as before implantation of artificial valve. Case Report: Patient with cardiologic history, previously percutaneus intervention were performed and left circumflex coronary artery were assessed as occluded. Computed tomography revealed anomalous origin of patent circumflex branch arising from right Valsava sinus. Conclusions: Selective percutaneus coronary angiography is challenging in case of coronary anomalies, there are only few indirect symptoms of anomalies. The advantage of computed tomography over classic coronarography is visibility of all patent coronary vessels after single administration of contrast medium. It is possible to describe its anatomic relations, evaluation of walls and its changes.
