Split right coronary artery: its definition and its territory

Fadi J Sawaya et al. Tex Heart Inst J. 2008.

Abstract

We report here, for perhaps the 1st time in the English-language literature, the extent of the territory fed by the anterior bifurcation of the (anomalous) split right coronary artery (RCA). A 64-year-old man presented with an occlusion of the anterior bifurcation of a split RCA--which resulted in an infarct that involved both the inferoseptal left ventricular wall and the anterior right ventricular free wall. Split RCA is the same anomaly as the improperly named "double right coronary artery." In reality, there are not 2 RCAs, but only split portions of the posterior descending branch of the RCA, with 2 separate proximal courses.

Keywords: Coronary vessel anomalies/diagnosis; myocardial infarction/diagnosis/physiopathology.
