Right conus artery

Looks like

The first small branch of the right coronary artery (sometimes with its own opening), running to the outflow funnel of the right ventricle.

What it does

Supplies the right ventricle's outflow and links with the left side as a backup route.

Keeping it well

Small; its catheter entry can trigger rhythm problems during angiography.
