Abstract

Intercoronary arterial connection between normal coronary arteries is a rare variant of coronary anatomy in which there is open-ended circulation. It is distinguished from collaterals seen in the occlusive coronary artery disease. We report a case of bidirectional intercoronary communication between the left circumflex artery and the right coronary artery without occlusive coronary artery disease, but with left anterior descending artery spasm.

Figure

  • Fig. 1 A: left selective coronary angiogram shows no significant obstructive disease of left coronary artery and retrograde filling of the right coronary artery (RCA). B: right selective coronary angiogram shows direct connection between the distal part of RCA and the left circumflex artery (LCX), without a critical lesion involving RCA and LCX.

  • Fig. 2 A: the significant stenosis of proximal LAD develops when ergonovine is administered intravenously in a dose of 50 ug. B: LAD spasm resolves with the injection of intracoronary nitroglycerine. LAD: left anterior descending artery.
