The vast majority of aortic dissections originate with an intimal tear in either the ascending aorta (65%), the aortic arch (10%), or just distal to the ligamentum arteriosum in the descending thoracic aorta (20%). [clarification needed] As blood flows down the false lumen, it may cause secondary tears in the intima.
As SA worsens, the vasa vasorum undergo hyperplastic thickening of their walls thereby restricting blood flow and causing ischemia of the outer two-thirds of the aortic wall. Starved for oxygen and nutrients, elastic fibers become patchy and smooth muscle cells die. If the disease progresses, syphilitic aortitis leads to an aortic aneurysm.
Heyde's syndrome; A stenotic aortic valve: Specialty: Cardiology, general surgery, Hematology: Symptoms: Aortic valve stenosis symptoms: Chest pain (angina) or tightness Shortness of breath, especially during exertion or when lying down Fatigue or weakness Irregular heartbeat or heart palpitations Dizziness or fainting episodes Gastrointestinal bleeding symptoms: Occult (hidden) or overt ...

Diagnosis of aortitis starts with physical examination and recording patient's medical history. Imaging tests such as magnetic resonance angiography, doppler ultrasonography, and positron emission tomography(PET) can be used to look at the blood vessels and blood flow, and highlight areas of inflammation. Condition is generally diagnosed based ...
An aortic aneurysm can occur as a result of trauma, infection, or, most commonly, from an intrinsic abnormality in the elastin and collagen components of the aortic wall. Aortic aneurysm development and progression have been directly associated with a deficiency of elastin as well as a loss of collagen type 1. [ 19 ]
Acute decompensated heart failure (ADHF) is a sudden worsening of the signs and symptoms of heart failure, which typically includes difficulty breathing , leg or feet swelling, and fatigue. [1] ADHF is a common and potentially serious cause of acute respiratory distress. The condition is caused by severe congestion of multiple organs by fluid ...
The standard for diagnosis of aortic stenosis is non-invasive testing with echocardiography. Cardiac catheterization is reserved for cases in which there is a discrepancy between the clinical picture and non-invasive testing, due to risks inherent to crossing the aortic valve, such as stroke. [7]
