Aortic stenosis is a common heart condition caused by a narrowing of the aortic valve, the valve that connects the left ventricle of the heart and the aorta. This condition can be congenital, meaning it was present since birth, or it can be acquired later in life. In either case, this narrowing can lead to serious cardiac problems, such as heart failure and stroke. It is estimated that more than 5 million people in the United States have aortic stenosis, making it one of the most common forms of heart disease.

What is Aortic stenosis
Aortic stenosis is a condition where the opening of the aortic valve — which is a crucial part of the heart — is narrowed. This narrowing restricts the flow of oxygen-rich blood from the left ventricle, which can lead to symptoms like chest pain, fatigue, and even fainting spells. In addition to being caused by age-related degeneration of the valve, aortic stenosis can also arise from an inherited condition known as the bicuspid aortic valve. In these cases, the valve may be thinner, or it may be misshapen, resulting in obstruction of blood flow.
Aortic valve disease
Aortic stenosis is a narrowing of the aortic valve that affects the left ventricle of the heart. In individuals with aortic stenosis, the narrowed valve forces the left ventricle to work harder to pump blood from the heart into the aorta. This can put an excessive amount of strain on the heart and can lead to serious health complications. Aortic stenosis can also cause a decrease in oxygen-rich blood circulation throughout the body, leading to fatigue, chest pain, and shortness of breath.
Aortic stenosis is a serious heart condition that affects the aortic valve. The aortic valve regulates the amount of blood that flows from the left ventricle of the heart to the aorta. In people with aortic stenosis, the valve becomes narrowed or stiff, preventing the heart from properly pumping blood. This causes an increase in blood pressure within the left ventricle and can lead to further complications, such as heart failure or stroke.
Symptoms of Aortic stenosis
Mild to severe aortic valve stenosis can occur. When the valve is severely narrowed, symptoms frequently develop. Aortic valve stenosis may go years without showing any symptoms in some persons.
Aortic valve stenosis symptoms might include:
a cardiac murmur, which is an irregular heartbeat, is audible with a stethoscope.
Angina or tightness in the chest when exercising
feeling lightheaded, woozy, or dizzy when active
breathlessness, especially while active
Especially at times of high exertion, fatigue
fluttering, rapid pulse (palpitations)
failing to eat enough (mainly in children with aortic valve stenosis)
not putting on enough pounds (mainly in children with aortic valves)
The stenosis of the aortic valve can cause heart failure. Fatigue, shortness of breath, and swelling ankles and feet are a few signs of heart failure.
Causes of Aortic stenosis
Knowing how the heart and heart valves normally function may be useful in understanding the reasons for the aortic valve.
There are four valves in the heart that maintain proper blood flow:
Heart valve
molar valve
three-lobed valve
respiratory valve
Every pulse causes the flaps (also known as cusps or leaflets) on each valve to open and close once. The valves occasionally fail to open or close properly. Blood flow is slowed or halted if a valve doesn’t fully open or seal.
The valve between the aorta and the lower left heart chamber (left ventricle) does not fully open in the aortic valve. The passageway via which blood leaves the heart and travels to the aorta is constricted (stenosis).
The heart has to work harder to pump adequate blood into the aorta and to the rest of the body when the aortic valve opening is restricted. The left ventricle may thicken and grow as a result of the heart having to work harder. The tension may eventually result in a weaker heart muscle, which may then cause heart failure and other major issues.
Risk factors
Aortic valve risk factors include:
old age
Congenital heart defects are disorders that affect the heart from birth, such as a bicuspid aortic valve.
long-term kidney disease
being afflicted heart disease risk factors include diabetes, high cholesterol, and high blood pressure
History of illnesses that can harm the heart, such as infective endocarditis and rheumatic fever
radiation treatment history for the chest
Prevention
The aortic valve may be avoided in several ways, including:
preventing rheumatic fever by taking precautions: When you have a sore throat, visit your doctor. Antibiotics are often effective in treating strep throat. Rheumatic fever can arise from untreated strep throat. The prevalence of rheumatic fever is higher in children and young adults.
maintaining heart health: Discuss the risk factors for heart disease and how to avoid or manage them with your healthcare physician. High cholesterol, obesity, and high blood pressure are a few of them. Aortic valve stenosis may be related to certain risk factors.
maintaining dental and gum health: Infected cardiac tissue and infected gums may be connected. The vascular narrowing can occur when infection-related cardiac tissue inflammation occurs.
Conclusion
Aortic stenosis is a condition in which the narrowing of the aortic valve results in a partial blockage of the flow of oxygenated blood from the left ventricle to the aorta. This narrowing can be caused by calcification of the aortic valve due to age or can be congenital, meaning it is present at birth. Without proper treatment, this condition can lead to serious complications including heart failure, stroke, and even death. Effective management of aortic stenosis can help preserve cardiac function, reduce symptoms, and improve the overall quality of life.
