Abstract

Coronary collateral circulation frequently develops in the presence of obstructive coronary lesions as an alternative source of blood supply. We present a case of rare direct communication between the circumflex and right coronary arteries in a 30-year-old male with continuity between the distal segments of the circumflex and right coronary artery and no coronary artery stenoses. Direct intercoronary connections may be seen in the absence of an occlusive coronary lesion, as a remnant of the fetal circulation in adult life. We present this case to increase awareness of this rare coronary variation and its clinical implications.
