Posterior left ventricular artery

Last revised by Dr Joachim Feger on 23 Jan 2021

The posterior left ventricular (PLV) artery, also known as the posterolateral artery or branch (PLA or PLB), 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 the typically right-dominant circulation as a terminal branch along with the posterior descending artery, 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.
