Aortic stenosis
AORTIC VALVE DISEASE THAT HAS PHYSICAL BASIS IN INCOMPLETE OPENING OF THE AORTIC VALVE
Aortic Stenosis; Congenital stenosis of aortic valve; Stenosis of aortic valve; Aorta valve stenosis; Aortic supravalvular stenosis; Aortic calcification; Aortic valve stenosis; Aortic sclerosis
Aortic stenosis (AS or AoS) is the narrowing of the exit of the left ventricle of the heart (where the aorta begins), such that problems result. It may occur at the aortic valve as well as above and below this level.
Aortic aneurysm

AORTA TO GREATER THAN 1.5 TIMES NORMAL SIZE.
Aortic aneurism; Aortic Aneurysm; Coronary hemorrhage; Aortic aneurysms
An aortic aneurysm is an enlargement (dilatation) of the aorta to greater than 1.5 times normal size.
Aortic regurgitation

AORTIC VALVE DISEASE THAT IS CHARACTERIZED BY LEAKING OF THE AORTIC VALVE OF THE HEART CAUSES BLOOD TO FLOW IN THE REVERSE DIRECTION DURING VENTRICULAR DIASTOLE, FROM THE AORTA INTO THE LEFT VENTRICLE
Aortic (valve) insufficiency; Quincke's sign; Hill's sign; Insufficiency of aortic valve; Aortic valve regurgitation; Traube's sign; Aortic valve insufficiency; Water-hammer pulse; Aortic incompetence; Aortic insufficiency
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.

Aortic valve
.svg?width=120)
The aortic valve is a valve in the heart of humans and most other animals, located between the left ventricle and the aorta. It is one of the four valves of the heart and one of the two semilunar valves, the other being the pulmonary valve. The aortic valve normally has three cusps or leaflets, although in 1–2% of the population it is found to congenitally have two leaflets. The aortic valve is the last structure in the heart the blood travels through before stopping the flow through the systemic circulation.
