Apart from the phenomenon of optical illusion, the presence of radiolucent lung between the cardiac border and the descending branch
of the right pulmonary artery is also believed to be responsible for this appearance.
There may be a long dominant posterior descending branch
of the RCA, terminating in the AIVS beyond the apex; a long parallel diagonal branch; or a dual LAD.
According to the proportional length of each vessel segment in the coronary artery tree, segments were graded with different maximum numbers of points: 5 points for the left main stem, 20 for the left anterior descending artery, 10 for the main diagonal branch, 5 for the first septal branch, 20 for the left circumflex artery, 10 for the obtuse marginal and posterolateral vessels, 20 for the right coronary artery, and 10 for the right posterior descending branch
3) In contrast to the current case, in the 2 cases in the previous report, (3) there was a single artery supplying the anterior wall of the left ventricle, consisting of a left anterior descending branch
with an initial intramural course.
The enhanced states were at finite fields along the descending branch
of a field sweep where [I.
