Aortic Valve Stenosis
Aortic valve stenosis occurs when the aortic valve of the heart fails to open completely, preventing the normal flow of blood out of the left lower chamber of the heart (ventricle), thus impeding the flow of oxygenated blood to the body. Aortic stenosis is one of the most common and most serious valve disease problems. Aortic stenosis is a narrowing of the aortic valve opening. Aortic stenosis restricts the blood flow from the left ventricle to the aorta and may also affect the pressure in the left atrium.
• Chest pain, pressure or tightness
• Fainting, also called syncope
• Palpitations or a feeling of heavy, pounding, or noticeable heartbeats
• Decline in activity level or reduced ability to do normal activities requiring mild exertion
When the aortic valve is obstructed, your heart needs to work harder to pump blood to your body. Eventually, this extra work limits the amount of blood it can pump and may weaken your heart muscle.
