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