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.
Regurgitation in or near the heart is often caused by valvular insufficiency (insufficient function, with incomplete closure, of the heart valves); for example, aortic valve insufficiency causes regurgitation through that valve, called aortic regurgitation, and the terms aortic insufficiency and aortic regurgitation are so closely linked as ...
Since increasing afterload will prevent blood from flowing in a normal forward path, it will increase any murmurs that are due to backwards flowing blood. [3] This includes aortic regurgitation (AR), mitral regurgitation (MR), and a ventricular septal defect (VSD).
Regurgitation may also (in part) be due to congenital malformation of the aortic valve or concomitant stretching of a tricuspid aortic valve. Life expectancy may be limited by severe aortic regurgitation. The aneurysm of the ascending aorta may also become so large that it can develop rupture or dissection as life-threatening complications.
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.
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 ...
