Aortic Valve Stenosis Symptoms, Treatment, Types & Surgery Aortic stenosis is abnormal narrowing of the aortic valve. A number of conditions cause disease resulting in narrowing of the aortic valve. When the degree of narrowing becomes significant enough to impede the flow of blood from the left ventricle to the arteries, heart problems develop. The oxygenated blood then returns to the left atrium and passes through the mitral valve into the left ventricle. 2  Blood is pumped by the left ventricle across the aortic valve into the aorta and the arteries of the body.

Aortic valve Aortic valve. The aortic valve is a valve in the human heart between the left ventricle and the aorta. It is one of the two semilunar valves of the heart, the other being the pulmonary valve. The heart has four valves and the other two are the mitral and the tricuspid valves. The aortic valve normally has three cusps or leaflets, although in 1–2% of the population it is found to congenitally have two leaflets.

Cardiac Auscultation in the Older Adult Aortic Stenosis. The aortic stenosis murmur is diamond-shaped and systolic and radiates along the aortic outflow tract. The peaking of the murmur moves toward S2 as the valve area narrows. Classically, the aortic stenosis murmur is heard best at the right upper sternal border (where it is harsh and noisy).

- Aortic valve stenosis is narrowing of the aortic valve. Many things can narrow this passageway between your heart and aorta. Causes of aortic valve stenosis include: Congenital heart defect. The aortic valve consists of three tightly fitting, triangular-shaped flaps of tissue called leaflets. Some children are born with an aortic valve that has only one (unicuspid), two (bicuspid) or four (quadricuspid) leaflets — not three.

- Aortic insufficiency (AI), also known as aortic regurgitation (AR), is the leaking of the aortic valve of the heart that causes blood to flow in the reverse direction during ventricular diastole, from the aorta into the left ventricle. As a consequence the cardiac muscle is forced to work harder than normal.[1]

Aortic Valve Disease Aortic valve stenosis is usually defined by restricted systolic opening of the valve leaflets, with a mean transvalvular pressure gradient of at least 10 mm Hg. The cause of the stenosis can be further defined based on the anatomy and disease process affecting the valve.alcific aortic stenosis, formerly referred to as degenerative, affects trileaflet aortic valves, often in patients with other risk factors for atherosclerotic disease. The aortic valve leaflets undergo an active disease process, with lipid deposition, inflammation, and osteo-calcific changes.

What are the causes of aortic stenosis? Normal valves have three leafs (tricuspid), but some valves have two leaflets (bicuspid). Typically, aortic stenosis due to calcification of a bicuspid valve appears earlier, in the 40s and 50s, while aortic stenosis due to calcification of a normal valve appears later, in the 70s and 80s. Hypertension, diabetes mellitus, hyperlipoproteinemia and uremia may speed up the process.

Aortic Valve Disease Aortic valve disease is a condition in which the valve between the main pumping chamber of your heart (left ventricle) and the main artery to your body (aorta) doesn't work properly. Aortic valve disease sometimes may be a condition present at birth (congenital heart disease), or it may result from other causes. Types of aortic valve disease include: 1  Aortic valve stenosis. 2  In this condition, the aortic valve opening is narrowed. 3  This narrowing prevents the valve from opening fully, which obstructs blood flow from your heart into your aorta and the rest of your body. 4  Aortic valve regurgitation.

Aortic insufficiency Aortic insufficiency (AI), also known as aortic regurgitation (AR), is the leaking of the aortic valve of the heart that causes blood to flow in the reverse direction during ventricular diastole, from the aorta into the left ventricle.n aortic insufficiency (AI), when the pressure in the left ventricle falls below the pressure in the aorta, the aortic valve is not able to completely close. This causes a leaking of blood from the aorta into the left ventricle.

Problem: Aortic Valve Stenosis What is aortic valve stenosis (AS)? 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. Watch an animation of aortic valve stenosis.

- Narrowing of a valve or an artery is called stenosis. A stenotic valve does not open completely and therefore it obstructs or blocks blood from moving through it normally. An artery can become stenotic as well, such that there is obstruction of blood flow through it to the organs of the body.

TAVR / TAVI - Transcatheter Aortic Valve Replacement TAVR or TAVI stands for transcatheter aortic valve replacement. It is an exciting technology that allows physicians to fix a severely narrowed aortic valve (aortic stenosis) without opening up the patient's chest. What is aortic stenosis? Aortic stenosis is a condition that results from narrowing of the aortic valve of the heart. This valve normally allows blood flow to be pumped from the main chamber of your heart to the rest of your body.

Grading aortic stenosis severity when the flow modifies the gradientvalve area correlation Grading aortic stenosis severity when the flow modifies the gradientvalve area correlation. Valvular aortic stenosis (AS) is the most frequent valvular disease in developed countries. The diagnosis of AS is classically confirmed by echocardiography, the standard tool for detecting and assessing the severity of the disease (1).

Low gradient âsevereâ aortic stenosis with preserved left ventricular ejection fraction Low gradient “severe” aortic stenosis with preserved left ventricular ejection fraction. Heart and Vascular Institute, Cleveland Clinic, Cleveland, Ohio, USA. Abstract: In developed nations, aortic stenosis (AS) is the most common valvular heart disease presentation, and its prevalence is increasing due to aging populations. Accurate diagnosis of the disease process and determination of its severity are essential in clinical decision-making.

Abstract Background SE may help to distinguish between true severe aortic stenosis and pseudosevere aortic stenosis in patients with low aortic valve area (AVA) and mean gradient. However, if rest flow rate is normal, then SE may not confer any additional diagnostic value, irrespective of resting left ventricular ejection fraction (LVEF) and indexed stroke volume (SVi).

Aortic Valve Regurgitation Aortic valve regurgitation is a condition in which the heart's aortic valve does not close properly. This allows blood to leak backward from the aorta into the left ventricle. The condition can be caused by several things, and over time may lead to symptoms such as chest pain, shortness of breath, heart failure, and fainting.
