Figure 2 Coronary angiography. A: Cineangiography in the right anterior oblique (RAO) cranial projection demonstrated a diminutive left anterior descending artery (LAD) terminating in the mid anterior wall. B: RAO caudal views demonstrated small obtuse marginal branches and an absence of left-to-left collateral vessels. C: The LAD extended less than two-thirds of its expected course. D: A watershed zone between the LAD and left circumflex artery territories.
