🆕 Visual: Left Coronary Artery (LCA) Branches This schematic details the LCA's origin from the left aortic sinus and its bifurcation: · Anterior Interventricular Artery (LAD): Descends in the anterior sulcus. Supplies the anterolateral myocardium via Diagonal Branches and the anterior septum via Anterior Septal Perforators. · Circumflex Artery (LCX): Courses in the left AV sulcus. Supplies the lateral left ventricle via the Left (Obtuse) Marginal Artery. Clinical Relevance: The LCA system is do
