Intercoronary communication (ICC) is a very rare subset with uni- or bidirectional blood flow between two or more coronary arteries. We present the case of a 58-year-old man with an acute coronary syndrome whose coronary angiography incidentally showed a surprising and very rare communication between the right coronary and left circumflex arteries %K Coronary artery anomalies (CAA) %K intercoronary communication (ICC) %K coronary angiography %U https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4731591/
