what is an aortic murmur?

Heart murmurs are sounds during your heartbeat cycle — such as whooshing or swishing — made by turbulent blood in or near your heart. These sounds can be heard with a stethoscope. A normal heartbeat makes two sounds like "lubb-dupp" (sometimes described as "lub-DUP"), which are the sounds of your heart valves closing.

Stenosis of the aortic or pulmonic valves will result in a systolic murmur, as blood is ejected through the narrowed orifice. Conversely, regurgitation of the same valves will result in a diastolic murmur, as blood flows backward through the diseased valve when ventricular pressures drop during relaxation.

Anatomical terminology. The mitral valve (/ˈmaɪtrəl/), also known as the bicuspid valve or left atrioventricular valve, is a valve with two flaps in the heart that lies between the left atrium and the left ventricle.

There are four valves in your heart including the mitral, tricuspid, aortic and pulmonic valves. The aortic valve is located between the left ventricle (lower heart pumping chamber) and the aorta, which is the largest artery in the body. Valves maintain one-way blood flow through the heart.

Heart murmurs are very common in babies and young children. In the vast majority of cases the heart is working normally and there isn't anything to worry about. In fact many young children have heart murmurs and neither they nor their parents will ever know anything about it.

The aorta (/eɪˈɔːrtə/ ay-OR-tə) is the main and largest artery in the human body, originating from the left ventricle of the heart and extending down to the abdomen, where it splits into two smaller arteries (the common iliac arteries).

Although not considered normal, not all murmurs are a cause for concern. A large majority of heart murmur in dogs are leaky mitral valves and can be monitored for several years before they require attention. However, these types of murmurs in certain breeds can quickly lead to the dog developing heart failure.

Heart murmurs are very common in cats. A heart murmur means that in addition to the normal lub-dub heart sounds, a vet can also hear extra sounds when listening with a stethoscope.

In Severe Aortic Stenosis there is a diamond shaped systolic murmur which lasts throughout systole. The murmur is loud and higher pitched than the murmur of mild aortic stenosis. It is caused by calcification of the aortic valve leaflets.

Mitral Valve Prolapse (Click with Late Systolic Murmur) Sounds. There is a medium pitched diamond shaped murmur which begins right after a mid systolic click and runs to the end of systole.

Aortic valve stenosis is the most common form of valvular heart disease in the elderly population and frequently occurs in conjunction with coronary artery disease (CAD).

Transcatheter aortic valve replacement (TAVR) is a minimally invasive procedure to replace a narrowed aortic valve that fails to open properly (aortic valve stenosis). In this procedure, doctors insert a catheter in your leg or chest and guide it to your heart.

Narrowing Aortic Valve Can Be Treated Without Open Heart Surgery. Narrowing of the aortic valve, called aortic stenosis, is a common and serious heart valve problem. Without treatment, it has a prognosis worse than most cancers. Once symptoms occur, they continue to worsen and few sufferers are alive in five years.

Aortic valve calcification is a condition in which calcium deposits form on the aortic valve in the heart. These deposits can cause narrowing at the opening of the aortic valve. This narrowing can become severe enough to reduce blood flow through the aortic valve — a condition called aortic valve stenosis.

The aortic valve is the gate between the main pumping chamber of the heart, the left ventricle, and the main artery of the body, the aorta. The aortic valve is able to open and close because it has leaflets (cusps). In a normal aortic valve there are three leaflets, and because of this it is called trileaflet.

Many heart murmurs aren't life-threatening and don't need treatment. But other heart murmurs do need treatment because they're a sign of an underlying problem with your heart. It's important to remember that if you've been diagnosed with a heart murmur, that doesn't mean you'll always have it.

Bicuspid aortic valve is a type of abnormality in the aortic valve in the heart. In bicuspid aortic valve, the valve has only 2 small parts (leaflets), instead of the normal 3. This condition can be present from birth (congenital).
