Aortic regurgitation (AR), also known as aortic insufficiency (AI), is the leaking of the aortic valve of the heart that causes blood to flow in the reverse direction during ventricular diastole, from the aorta into the left ventricle. As a consequence, the cardiac muscle is forced to work harder than normal.
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 ...
It sometimes radiates to the carotid arteries. In mild aortic stenosis, the crescendo-decrescendo is early peaking. Whereas in severe aortic stenosis, the crescendo is late-peaking. In severe cases, obliteration of the S2 heart sound may occur. Stenosis of Bicuspid aortic valve is like the aortic valve stenosis heart murmur. But, one may hear a ...
A bicuspid aortic valve may cause the heart's aortic valve to narrow (aortic stenosis). [6] This narrowing prevents the valve from opening fully, which reduces or blocks blood flow from the heart to the body. In some cases, the aortic valve does not close tightly, causing blood to leak backward into the left ventricle. [10]
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. Aneurysms may affect the right (65–85%), non-coronary (10–30%), or rarely the left (< 5%) coronary sinus. [1]
Aortic stenosis due to calcification of tricuspid aortic valve with age [16] comprises >50% of the disease. Aortic stenosis due to calcification of a bicuspid aortic valve [16] comprises about 30-40% [15] of the disease. Hypertension, diabetes mellitus, hyperlipoproteinemia and uremia may speed up the process of valvular calcification. [15]
Aortic valve repair or aortic valve reconstruction describes the reconstruction of both form and function of the native and dysfunctioning aortic valve. Most frequently it is applied for the treatment of aortic regurgitation. It can also become necessary for the treatment of an aortic aneurysm, less frequently for congenital aortic stenosis. [53]
On a gross level, there is a pear-shaped, symmetric enlargement due to proximal aortic dilation. 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 ...
