Congenital anomaly of the true double-lumen right coronary artery: An extremely rare case

Abstract

We read with interest the report by Lee et al. entitled “Congenital anomaly of the true double-lumen right coronary artery: an extremely rare case” [1]. Previously reported cases of the double right coronary artery (DRCA) mostly described anomalies with a common proximal right coronary artery (RCA) that diverged into two separate distal branches. Meanwhile, the current case described by Lee et al. is a type of fenestrated RCA anomaly in which the common proximal RCA diverges into two separated branches proximally and converges back to a common lumen distally.
