Supravalvular aortic stenosis (SVAS) is a heart defect that develops before birth. This defect is a narrowing (stenosis) of the large blood vessel that carries blood from the heart to the rest of the body (the aorta). The condition is described as supravalvular because the section of the aorta that is narrowed is located just above the valve that connects the aorta with the heart (the aortic valve). Some people with SVAS also have defects in other blood vessels, most commonly stenosis of the artery from the heart to the lungs (the pulmonary artery). An abnormal heart sound during a heartbeat (heart murmur) can often be heard during a chest exam. If SVAS is not treated, the aortic narrowing can lead to shortness of breath, chest pain, and ultimately heart failure.
Description
Supravalvular aortic stenosis (SVAS) is a heart defect that develops before birth. This defect is a narrowing (stenosis) of the large blood vessel that carries blood from the heart to the rest of the body (the aorta). The condition is described as supravalvular because the section of the aorta that is narrowed is located just above the valve that connects the aorta with the heart (the aortic valve). Some people with SVAS also have defects in other blood vessels, most commonly stenosis of the artery from the heart to the lungs (the pulmonary artery). An abnormal heart sound during a heartbeat (heart murmur) can often be heard during a chest exam. If SVAS is not treated, the aortic narrowing can lead to shortness of breath, chest pain, and ultimately heart failure.
The severity of SVAS varies considerably, even among family members. Some affected individuals die in infancy, while others never experience symptoms of the disorder.

Aortic stenosis
The aortic valve is a heart valve that lies between the left ventricle and the aorta. In aortic stenosis, when the aortic valve opens to let blood pump through, it does not open as widely as it would normally. The opening between the... What is aortic stenosis. Aortic stenosis is a narrowing of the aortic valve which is the valve between the left.

Congenital heart disease
Congenital heart disease is a condition where an abnormality (defect) develops in the heart before birth. There are a number of types of congenital heart defect. Some are mild and cause few problems; others are life-threatening for the baby. Blockage of blood flow at or near the valves of the heart ca... Valves may be abnormally shaped or narrowed.
Patient information leaflet
Aortic regurgitation
Aortic regurgitation is sometimes called aortic incompetence or a leaky aortic valve. In aortic regurgitation the valve does not close properly. The aortic valve is a heart valve that lies between the left ventricle and the aorta. Therefore, blood leaks back (regurgitates) into the left ventricle from the aorta. In some cases, aortic regurgitation.
Patient information leaflet
Heart valve disease
Heart valves sit in between the chambers of the heart and control the blood flow through the heart. There are four common types of heart valve problem - mitral stenosis, mitral regurgitation , aortic stenosis and aortic regurgitation. The leaflet called Anatomy of the heart includes details about the function of the heart and how the heart beats..

Aortic dissection
An aortic dissection is a rare, serious condition. The inner layer of the aorta (the biggest blood vessel in the body, coming directly from the heart) tears. Blood then surges through the tear. A severe injury to the chest may also cause aortic dissection. Aortic stenosis , previous cardiac surgery, having a history of aortic diseases in your.

Can I take Amlodipine and Quetiapine together?
Severe liver disease Amlodipine is broken down very slowly by the liver; if you have liver problems, the dose must be adjusted carefully to avoid toxic build-up... Severe heart disease (Aortic Stenosis) Amlodipine should be used with extreme caution if you have narrowing of the aortic heart valve (aortic stenosis), as it can cause a dangerous drop.
