Acute aortic syndrome (AAS) describes a range of severe, painful, potentially life-threatening abnormalities of the aorta. [1] These include aortic dissection, intramural thrombus, and penetrating atherosclerotic aortic ulcer. [2] AAS can be caused by a lesion on the wall of the aorta that involves the tunica media, often in the descending ...
Aortic aneurysm; Figure A shows a normal aorta. Figure B shows a thoracic aortic aneurysm (which is located behind the heart). Figure C shows an abdominal aortic aneurysm located below the arteries that supply blood to the kidneys. Specialty: Cardiology, Vascular surgery: Symptoms: abdominal pain and back pain: Complications: Hemorrhaging ...
Aortic unfolding is an abnormality visible on a chest X-ray, that shows widening of the mediastinum which may mimic the appearance of a thoracic aortic aneurysm. [1]With aging, the ascending portion of the thoracic aorta increases in length by approximately 12% per decade, whereas the diameter increases by just 3% per decade.
The aortic wall dilatation at the commissural level causes the cusps to effectively shorten and prevent them from converging during systole, which results in aortic valve incompetence. The arch is typically spared from the aneurysmal process, though it may involve the entire ascending aorta. The ectatic aorta may experience dissections.
Aneurysm of the aortic sinus, also known as the sinus of Valsalva, is a rare abnormality of the aorta, the largest artery in the body.The aorta normally has three small pouches that sit directly above the aortic valve (the sinuses of Valsalva), and an aneurysm of one of these sinuses is a thin-walled swelling.
The Stanford classification is divided into two groups, A and B, depending on whether the ascending aorta is involved. [39] A – involves the ascending aorta and/or aortic arch, and possibly the descending aorta. The tear can originate in the ascending aorta, the aortic arch, or more rarely, in the descending aorta. It includes DeBakey types I ...
An aortic aneurysm is a balloon-like bulge in the aorta, the large artery that carries blood from the heart through the chest and torso, according to the Centers for Disease Control and Prevention ...
One of the most notable associations with BAV is the tendency for these patients to present with ascending aortic aneurysmal lesions. [8] The extracellular matrix of the aorta in patients with BAV shows marked deviations from that of the normal tricuspid aortic valve, specifically reduced Fibrillin-1.
