Right coronary artery chronic total occlusion in presence of anomalous origin of left coronary artery.

ABSTRACT

Right sinus origin of left coronary artery is a very uncommon congenital coronary anomaly. The presence of an associated totally occluded right coronary artery represents an exceedingly rare picture. An accurate morphologic identification of anomalous arteries, by multi-detector computed tomography, is mandatory before planning any therapeutic intervention. We report an interesting case of chronic total occlusion of the right coronary artery in a young patient with anomalous left coronary artery.
