![]() ![]() With the pulmonary trunk, the ascending aorta is invested in a common sheath of serous visceral pericardium, anterior to the transverse pericardial sinus. Last updated: Summary Aortic coarctation is characterised by a blood pressure differential between upper and lower extremities (upper >lower). The arch travels backward, so that it ultimately runs to the left of the trachea. The aorta classified as a large elastic artery, and more information on its internal structure can be found here. The aortic arch, arch of the aorta, or transverse aortic arch ( English: / ertk / 1 2) is the part of the aorta between the ascending and descending aorta. It terminates at the level of L4 by bifurcating into the left and right common iliac arteries. In a young patient, a prominent ascending aorta, especially when combined with signs of left ventricular hypertrophy should raise suspicion of aortic stenosis. The aorta can be divided into four sections: the ascending aorta, the aortic arch, the thoracic (descending) aorta and the abdominal aorta. This should only be the case in the older ectatic or dilated artery. ![]() The next portion of the aorta is the aortic arch. The coronary arteries that supply blood to the heart branch off of the ascending aorta. It is located obliquely just to the left of the midline at the level of the. The part of the aorta that arises from the left ventricle of the heart is called the ascending aorta. The ascending aorta ascends slightly towards the right of midline where it can be seen as part of the mediastinal outline on a chest radiograph. The ascending aorta is the first part of the aorta and begins at the sinotubular junction (the junction of the aortic root and ascending aorta) and terminates as it exits the fibrous pericardium where it becomes the aortic arch, in the transthoracic plane (of Ludwig ). Twenty-five patients were female (41.6), and the age of the patients ranged from 4 to 120 days (median, 19.5 days). Immediately above the three aortic sinuses, the normal tubular configuration of the aorta is attained - at the sinotubular junction. Methods: Medical records of 60 patients undergoing aortic arch reconstruction for AAH from 2014 to 2019 were retrospectively reviewed. These arise from the right and left aortic sinuses (of Valsalva) respectively, which (along with the non-coronary sinus) are out-pouchings of the aortic wall above each cusp of the aortic valve. It normally has only two branches (although technically these usually arise form the aortic root), the right coronary artery and the left coronary artery. It is located obliquely just to the left of the midline at the level of the third intercostal space. The ascending aorta is the first part of the aorta and begins at the sinotubular junction (the junction of the aortic root and ascending aorta) and terminates as it exits the fibrous pericardium where it becomes the aortic arch, in the transthoracic plane (of Ludwig). Pathology Classification Right-sided arches can be divided into at least three types. ![]()
