We present a case report of two rare arterial anomalies diagnosed during transradial coronary catheterization—arteria lusoria (aberrant right subclavian artery) and superdominant right coronary artery. Importantly, these anomalies may cause difficulty in performance or interpretation of catheterization procedure, especially in urgent situation and with wide acceptance of transradial approach. To the best of our knowledge, the combination of these anomalies has never been described in the literature.
