Abstract: Cardiac catheterization in a 55-year-old man, with a 6-month history of atypical chest pain and Q-waves in DII, DIII and AVF, showed concentric left ventricular (LV) hypertrophy and a large intercoronary connection between right coronary artery (RCA) and circumflex artery (CX), with bidirectional blood flow. Although the RCA and CX were normal, selective injection of CX filled RCA retrogradely and in the same way selective injection of RCA filled CX. Possible mechanisms and literature are reviewed.

“…The conduit appears to be a continuity of the LAD and the posterior descending artery branch of the RCA. Similar communications between coronary arteries were reported as early as 1701 by Ruyschii and has been described as a coronary arch by Greenberg et al 7 They are rarely seen during coronary angiography, 1,2,4,8–17 and are usually found connecting the right and circumflex arteries.…”

“…anomalous origin) have been associated with fatal cardiac events [8,9]. A few number of reports in the literature are referred to this kind of coronary circulation, as a result of coronary angiography imaging [1][2][3][4][5][6][7][10][11][12][13][14][15][16][17][18][19][20][21]. The predominant symptom at presentation was chest pain, usually atypical and non invasive diagnostic procedures had doubtful results.…”

“…Almost all reported cases demonstrated chest pain suggesting of myocardial ischemia. [6][7][8] We found one case with ischemic ECG changes during exercise electrocardiography 9) and one case with perfusion defect during exercise myocardial perfusion imaging. 10) We did not perform spasm provocation test as the symptoms did not occur in the early morning typical for the coronary spasm.…”
