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]
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]
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.
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. Aortic valve replacement – Replacement of the aortic valve due to aortic ...
An aortic homograft is an aortic valve from a human donor, retrieved either after their death or from a heart that is removed to be replaced during a heart transplant. [12] A pulmonary autograft, also known as the Ross procedure , is where the aortic valve is removed and replaced with the patient's own pulmonary valve (the valve between the ...
A quadricuspid aortic valve (QAV) is a rare congenital heart defect characterized by the presence of four cusps, instead of the usual three found normally in the aortic valve. [1] It is a defect that occurs during embryological development of the aortic trunk during gestation. [2]
