| ===Overview===
| |
| The "LAD", or '''left anterior descending artery''' (or '''anterior interventricular branch of the [[left coronary artery]]''', or '''anterior descending branch''') passes at first behind the [[pulmonary artery]] and then comes forward between that vessel and the [[left auricula]] to reach the [[anterior interventricular sulcus]], along which it descends to the [[incisura apicis cordis]].
| |
| | |
| In 78% of cases, it reaches the [[apex of the heart]].
| |
| | |
| It supplies the anterolateral [[myocardium]], apex, and [[interventricular septum]]. The LAD typically supplies 45-55% of the [[left ventricle]] (LV).
| |
| | |
| The LAD gives off two types of branches: ''septals'' and ''diagonals''.
| |
| * Septals originate from the LAD at 90 degrees to the surface of the heart, perforating and supplying the intraventricular septum.
| |
| * Diagonals run along the surface of the heart and supply the lateral wall of the LV and the anterolateral [[papillary muscle]].
