Conal Artery

The normal coronary arteries of the post mortem specimen have been injected with barium. The heart is projected in AP (a, b) and lateral projection (c, d). The conal artery is the first branch of the RCA and it supplies the right ventricular outflow tract. It collateralizes with the smaller counterpart which is a branch of the left coronary artery. It is magnified and displayed with red overlay in (b) and (d). The white arrow shows a branch of the smaller conal artery arising from the LCA.
