Case
A 48 year-old male patient referred to cardiology clinic with typical anginal symptoms. There was not any remarkable disease in the patient’s previous medical history. After stress testing, the patient underwent coronary angiography (CAG). In proximal right coronary artery (RCA) chronic total occlusion was detected and two collaterals originated from proximal part of the occlusion, retrogradely filling left anterior descending (LAD) artery which also had chronic total occlusion (Panel A). Following the retrograde filling of LAD, septal collaterals originated from the LAD were seen to fill distal RCA retrogradely again (Panel 2-3-4). Those united collaterals were successful at providing the blood supply, although with the occlusion of both RCA and LAD, a large area was under at risk. The patient underwent coronary artery bypass surgery after the CAG.
