Figure 2 Correspondence between the myocardial segments analyzed on the biplane left ventricular angiogram (analysis of myocardial wall motion, left panels) and the two apical echocardiographic views (analysis of tissue Doppler imaging-derived preejection velocities, right panels): myocardial segments 1, 2, 3, 6, and 7 were analyzed on the right anterior oblique (RAO) projection and in the apical two-chamber view, respectively. Myocardial segments 4, 5, and 8 were analyzed in the left anterior oblique (LAO) projection plus 20° cranial inclination and the apical long-axis view, respectively. Myocardial segments 1, 2, 3, 4, and 5 were considered to belong to the perfusion territory of the left anterior descending coronary artery; myocardial segments 6, 7, and 8 were considered to belong to the perfusion territory of the dominant right coronary artery (15,16).
