The anomalous origin of the left coronary artery
from the pulmonary artery (ALCAPA or Bland-White-Garland syndrome) is a rare congenital heart defect with an incidence of 1 in 300.
After birth vascular resistance of the pulmonary artery starts to decrease and blood flow from the pulmonary artery into the left coronary artery
First, each coronary artery originated one interventricular branch, that is, the left coronary artery
originated the paraconal interventricular branch and the right one, the subsinusal interventricular branch.
In the same heart, the left coronary artery
was originating from the pulmonary trunk at its posterior wall, emerged between the pulmonary trunk and the left auricle and continued as the anterior interventricular branch, there being no circumflex branch (Fig.
Finally the echocardiography revealed left coronary artery
arising from pulmonary artery with retrograde flow of blood.
It was showed that the mean of the left coronary artery
diameters of the KD model and IVIG treatment groups was significantly larger than that of the normal control group on days 7, 14, 28, 56.
There are four variants of anomalous left coronary artery
arising from right sinus of valsalva namely posterior or retroaortic course (Fig.
Routine cath-lab procedure started with left coronary artery
catheterization attempt, but it was unsuccessful and no vessel angiography could be visualized by injecting contrast in left coronary sinus.
Previous studies have shown that the three-dimensional wall pressure gradient (WPG) is lower in proximal left coronary artery
regions, where atherosclerosis often develops, in contrast to distal segments.
The right coronary artery arises from the anterior coronary sinus and the left coronary artery
from the left posterior aortic sinus.
Anatomically, the most favorable patients for trans-catheter occlusion are those with small defects situated midway between the pulmonary artery bifurcation and the semilunar valves, away from the left coronary artery
ostium and the semilunar valves (4, 7, 8).
Anatomical variations of coronary dominance are common, and they are characterized by the presence of a coronary branch irrigating SAN, which could be originated from either right or left coronary artery
(Gray & Mayo, 1988).
Distribution of Bridging in Coronary Artery: Myocardial bridging was observed only in left anterior descending branch of left coronary artery
(LAD) with a percentage of 3.
05); (4) among these 19 kinds of CCAAs, there were significant differences of the incidence of the following kinds of CCAAs between Uyghur and Han: Left coronary artery
(LCA) high location (?
