In all the specimens, the RCA arose from the right
aortic sinus and traversed the coronary sulcus before giving rise to the PIB on the posterior surface of the heart.
Frozen
aortic sinus sections were stained with 2 [micro]M dihydroethidium (DHE) (ThermoFisher Scientific) in PBS and were analyzed immediately using a fluorescence microscope.
In this study, single ostium was the most frequent findings (78%), double ostia were seen in 20 hearts (20%), three ostia were seen in two cases (2%) at anterior
aortic sinus (Figure 1).
066% of patients who undergo CCA and is characterized by a single coronary ostium originating from the
aortic sinus (Fig.
In all instances, LCA arose from the left posterior
aortic sinus and extended to the left behind the pulmonary trunk for a mean distance of 5 mm and divided into anterior interventricular and CX arteries (Fig.
In the second case, the right coronary artery was originating from the left
aortic sinus from its mid portion and emerged on the sternocostal surface by passing between ascending aorta and pulmonary trunk, reached the atrioventricular sulcus and had a normal course thereafter.
Coronary artery angiography was performed prior to RFCA at the CVS or
aortic sinus to confirm the distance from the ablation catheter tip to the coronary artery.
The pathological anatomy of deficiencies between the aortic root and the heart, including
aortic sinus aneurysms.
The right coronary artery arises from the anterior coronary sinus and the left coronary artery from the left posterior
aortic sinus.
4 Composite
aortic sinus of Valsalva graft type of biological valve prosthesis;
4) classification, it can be categorized into the IA group which means that a solitary ostium in the left
aortic sinus (I) is unassociated with an aberrant-coursing coronary artery (anatomic SCA) (A).
SUMMARY: A third coronary artery (TCA) has been defined as a direct branch from the right
aortic sinus (RAS) that contributes to the vascularization of the infundibulum of the right ventricle (RV).
