Narrowing (stenosis) of the aortic valve, the valve between the left ventricle of the heart and the aorta. This narrowing impedes the delivery of blood to the body through the aorta and makes the heart work harder. The need for surgery depends on the degree of stenosis. A procedure called balloon valvuloplasty has been used in some cases of aortic [..]

Narrowing of the aortic valve.

Aortic Stenosis is the hardening of the aortic valve that stops blood from returning to the heart once it has been pushed out. This hardening causes the left heart to have to work much harder to try a [..]

 A progressive disease that affects the aortic valve of the heart.

A Pathological Constriction that can occur above (supravalvular Stenosis), below (subvalvular Stenosis), or at the Aortic Valve. It is characterized by restricted outflow from the LEFT VENTRICLE into [..]

A Pathological Constriction occurring in the region below the Aortic Valve. It is characterized by restricted outflow from the LEFT VENTRICLE into the Aorta.

A Pathological Constriction occurring in the region above the Aortic Valve. It is characterized by restricted outflow from the LEFT VENTRICLE into the Aorta.

A narrowing of the aorta in the region below the aortic valve.

A narrowing of the aorta in the region above the aortic valve.

Progressive narrowing of the aortic valve resulting in the obstructed passage of blood from the left ventricle into the aorta. Causes for aortic stenosis include rheumatic fever, congenital and idiopathic sclerosis. Chronic stenosis can lead to left ventricular enlargement and congestive heart failure. (27 Sep 1997)
