The posterior left ventricular (PLV) artery, also known as the posterolateral artery (PLA), is a terminal branch of the coronary arterial system supplying the inferior portion of the heart. It usually arises from the right coronary artery (in a right dominant circulation) but can less commonly arise from the circumflex and rarely from the left anterior descending artery. This artery can sometimes be paired or have multiple branches.
