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.
Just like aortic stenosis, treatment for aortic regurgitation is replacement of the valve after symptoms and left ventricular dysfunction develops. SUMMARY All right, as a quick recap…. Aortic stenosis happens if the aortic valve doesn’t open all the way, and aortic valve regurgitation happens if the valve doesn’t close all the way.
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]
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 aortic aneurysm, or less frequently for congenital aortic stenosis. [8]
Stenosis of Bicuspid aortic valve is like the aortic valve stenosis heart murmur. But, one may hear a systolic ejection click after S1 in calcified bicuspid aortic valves. Symptoms tend to present between 40 and 70 years of age. Mitral regurgitation is a holosystolic murmur. One can best hear it at the apex location and it may radiate to the ...
Aortic valve replacement is also recommended in patients that are asymptomatic but have chronic severe aortic regurgitation and left ventricular ejection fraction of less than 50%. [8] Hypertension is treated in patients with chronic aortic regurgitation, with the anti-hypersensives of choice being calcium channel blockers, ACE inhibitors, or ...
