PP-248 A Very Rare Coronary Anomaly: Unidirectional Intercoronary Communication Between The Circumflex And Right Coronary Arteries

[...]with the selective injection of the right coronary artery in a anterior-posterior cranial view, the RCA and distal portion of left circumflex artery were simultaneously visualised, (Figure 1A,B) whereas left coronary injection did not fill the right coronary artery (unidirectional intercoronary communication). Sometimes, these connections may play a protective role, if the coronary artery obstruction has developed in one of the two connecting vessels.
