Cardiac anatomy


From the anterior view, the left and right coronaries, and the myocardial segments they supply, are shown. Note that the apex of the left ventricle is supplied by the left anterior descending artery and the anterior left ventricular wall by diagonals from the left anterior descending artery (LAD). The inferior left ventricular wall receives its supply of bloodflow by the posterior descending artery arising from the right coronary artery in this individual who is identified as a coronary artery configuration known as "right dominant".

Note also that the atrioventricular node is supplied by a short vessel at the bend of the right coronary artery before the take-off of the posterior descending artery at a position known as the "crux" of the heart.
