The aortic valve normally has three cusps or leaflets, although in 1–2% of the population it is found to congenitally have two leaflets. [1] The aortic valve is the last structure in the heart the blood travels through before stopping the flow through the systemic circulation. [1]
Causes include being born with a bicuspid aortic valve, and rheumatic fever; a normal valve may also harden over the decades due to calcification. [2] [1] A bicuspid aortic valve affects about one to two percent of the population. [1] As of 2014 rheumatic heart disease mostly occurs in the developing world. [1]
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.
Bicuspid aortic valve; Other names: Bicommissural aortic valve [1] The aortic valve controls outflow of blood from the left ventricle of the heart through the aorta (valve is indicated within the yellow highlighted box). A normal aortic valve is tricuspid. Five types of bicuspid valve are shown, with Type 1 being most prevalent.
Stenosis commonly occurs from calcification of the valve, which happens prematurely in those with a bicuspid aortic valve. Stenosis of the aortic valve produces a harsh systolic murmur that classically radiates in the carotid arteries as well as pulsus parvus et tardus.
