  • Left coronary artery: This is the artery that originates from the left side of the Aorta. Most commonly, it bifurcates into two different arteries: the circumflex artery and the left anterior descending artery. It supplies oxygenated blood to the left part of the heart. (1,3)

Anterior interventricular artery

  • Anterior interventricular artery: This artery originates from the left main coronary artery, descends along the interventricular sulcus, and gives rise to other important branches. (1,2,3)
    • Conal branch of anterior interventricular artery: It is a small branch from the anterior interventricular artery that supplies the conus arteriosus, which is part of the right ventricle of the heart. (1,3)
    • Anterior ventricular branches of anterior interventricular artery: These branches of the anterior ventricular artery supply the anterior wall of the heart(2,3)
      • Diagonal branch of anterior interventricular artery: Most commonly, this artery branches off diagonally from the anterior interventricular artery to supply blood to the left side of the heart.(1,3)
    • Septal branches of anterior interventricular artery: These arteries branch off the anterior interventricular artery to supply a significant portion of the wall that divides the left and right ventricles of the heart, also known as the interventricular septum. (1, 3)

Circumflex artery of heart

Left Coronary Artery: Circumflex Artery, बायाँ कोरोनरी धमनी: परिश्रांत धमनी, 左冠状动脉：回旋支, Left Coronary Artery: Circumflex Artery, Левая коронарная артерия: Окружающая артерия, الشريان التاجي الأيسر: الشريان الدائري, Left Coronary Artery: Circumflex Artery, Arteri Koroner Kiri: Arteri Sirkumfleks, الشريان التاجي الأيسر: الشريان الدائري, বাম করোনারি আর্টেরি: সার্কামফ্লেক্স আর্টেরি, Left Coronary Artery: Circumflex Artery, Ліва коронарна артерія: Обхідна артерія, Sol Koroner Arter: Circumflex arter, الشريان التاجي الأيسر: الشريان الدائري, Động mạch vương miện trái: Động mạch vòng, หลอดเลือดดวงกามซ้าย: หลอดเลือดหวงกลาง.

  • Circumflex artery of heart: The circumflex artery curves around the heart, supplying blood to the left atrium and the side and back of the left ventricle. (1,2,3)
    • Atrial branches of circumflex artery of heart: Atrial branches of circumflex artery of heart: The atrial branches of the circumflex artery supply blood to the left atrium of the heart. (2,3)
      • Atrial anastomotic branch of circumflex artery of heart: The atrial anastomotic branch is a connecting branch between the circumflex artery and other arteries supplying the left atrium.
    • Left marginal branch of circumflex artery of heart: The left marginal branch of the circumflex artery supplies blood to the lateral wall of the left ventricle. (1,2,3)
    • Inferior left ventricular branch of circumflex artery of heart: The inferior left ventricular branch of the circumflex artery descends to the inferior wall of the left ventricle, supplying it with blood. (2,3)
