Aortic Stenosis Scientific Journals
Aortic valve
stenosis — or
stenosis — occurs when the heart's semilunar valve narrows. When the blood flow through the semilunar valve is reduced or blocked, your heart must work harder to pump blood to your body. Eventually, this extra work limits the quantity of blood it can pump, and this will cause symptoms also as possibly weaken your cardiac muscle . Some people with semilunar valve
stenosis might not experience symptoms for several years. Signs and symptoms of aortic valve
stenosis may include: Abnormal heart sound (heart murmur) heard through a stethoscope Chest pain (angina) or tightness with activity. Feeling faint or dizzy or fainting with more activity.Shortness of breath, especially when you have been active. Fatigue, especially during times of increased activityHeart palpitations — sensations of a rapid, fluttering heartbeat Not eating enough (mainly in children with aortic valve stenosis)Not gaining enough weight (mainly in children with semilunar valve stenosis). The semilunar valve consists of three tight-fitting , triangular-shaped flaps of tissue called cusps. Some children are born with an semilunar valve that has only two (bicuspid) cusps rather than three. People can also change state with one (unicuspid) or four (quadricuspid) cusps, but these are rare.This defect might not cause any problems until adulthood, at which era the valve may begin to narrow or leak and should got to be repaired or replaced.
