What valve causes the second heart sound?
The closing of the mitral and tricuspid valves results in the first heart sound. The closing of the aortic and pulmonic valves results in the second heart sound.AV valve
For what reasons may an aortic valve replacement surgery be needed?
Aortic valve replacement surgery will be required if the valve in the heart is either too narrow for all of the blood to pass through or if the valve is leaking. This valve is very important as it prevents blood from rushing back into the heart after it has been pumped out.
What prevents blood from flowing back into the heart?
The valve
Who needs an artificial heart valve?
An artificial heart valve is needed if your natural valve is leaking beyond a point that is causing the chambers (ventricles) to enlarge thus reducing blood flow through the lungs and creating increased pulmonary pressure. With a new valve the back pressure is eliminated and the heart becomes a much more effective pump.
What does it mean when blood flows backwards in heart?
It could mean that you have Pulmonary Arterial Hypetension.
What is a leaking aortic valve?
A leaking aortic valve means that when your hears pumps blood through the valve, that the valve does not close of properly when it should. This causes your heart to have to work harder because some of the blood it pumps leaks back into the heart and needs to be pumped out again.
What is the function of the aortic valve?
The aortic valve functions as a one-way valve between the heart and the rest of the body. Blood is pumped from the left ventricle of the heart, through the valve, and down the aorta, which in turn supplies blood to all of the organs in the body. Between heart contractions, the valve closes, preventing blood from flowing backwards into the heart. The function of the aortic valve is then twofold: (1) It provides a route for which blood can leave the heart, and (2) It prevents blood that has already left the heart from leaking backwards into the heart.
In humans what results when a valve is leaking blood backwards in the heart?
not very much as it turns out. Many people have murmurs as these are commonly called. This is where the valve regurgitates blood through the leaking valve back into the chamber or vessel it came from. A third of the population have one or multiple murmurs. It only gets dangerous when the leaking becomes severe, this can be calculated only by an echocardiogram. If it becomes severe, Dr.s may intervene and either bolster the valve with a ring or replace the valve altogether with bovine, porcine or mechanical valves.
What valve causes the second heart sound?

What is a leaky valve that allows backflow of blood?
A leaky valve that allows backflow of blood is commonly known as a valve insufficiency or incompetence. This condition can lead to issues like regurgitation, where blood flows backward through the valve when it should be moving forward. Treatment may involve medication or surgery, depending on the severity.
What is regurgitated blood from incompetent valve?
Regurgitated blood from an incompetent valve refers to blood leaking backwards through a heart valve due to it not closing properly. This can lead to symptoms such as palpitations, shortness of breath, and fatigue as the heart has to work harder to compensate for the leakage. Treatment may involve medications to manage symptoms or surgical repair/replacement of the valve.
For what reasons may an aortic valve replacement surgery be needed?
Aortic valve replacement surgery will be required if the valve in the heart is either too narrow for all of the blood to pass through or if the valve is leaking. This valve is very important as it prevents blood from rushing back into the heart after it has been pumped out.
What prevents blood from flowing back into the heart?

What happens in heart?
In heart has a four valve the two valve is pump the up and the others valve pump the blood down. heart is pump the blood

What is the Improper closure of valve between atrium and ventricle during systole?
The improper closure of the valve between the atrium and ventricle during systole results in a condition called mitral valve prolapse. This can lead to blood leaking back into the atrium when the heart contracts, causing symptoms such as heart murmurs, fatigue, and shortness of breath. In severe cases, it may require treatment such as medication or surgery to prevent complications.
What if the name of the valve on the vessel that takes blood from the heart?
The valve on the aorta (the vessel taking blood away from the heart) is called the "aortic valve".
