Abstract

Intercoronary communication is a rare congenital coronary anomaly. We present a case of a 48-year-old man with an incidentally discovered communication between the right and circumflex coronary arteries, who was admitted with chest tightness and exertional dyspnea. The initial diagnosis was made using electrocardiogram-gated multidetector computed tomography.

  Fig. 1 Communication between the right and circumflex coronary arteries discovered incidentally by multidetector computed tomography. Three dimensional volume rendered images (A, B), and curved multiplanar reformatted image (C) showing the posterolateral branch of the right coronary artery (RCA) communicating (arrow) with the distal left circumflex coronary artery (LCX). Coronary angiography with selective (D, E) and simultaneous injection (F) into the right and left coronary arteries showing the connection (arrow) between the posterolateral branch of the RCA and the distal LCX. There is no significant coronary artery stenosis.
