If the aortic valve problem is causing symptoms replacing it can almost immediately improve heart function and the ability to exert yourself. It can also reduce the need for medications, especially diuretics.
However, there is a 3-5% operative mortality rate and a complication rate of 2-3% per year which sometimes requires re-operation. There is a 1% Death Rate per year after the surgery that is directly attributable to the implant.
Without the surgery the mortality rate of even severe aortic stenosis is less than 1% if no symptoms are present. However, the mortality rate goes up to 25% per year in patients with symptoms. For this reason, the surgery is felt to be clearly beneficial in symptomatic patients but controversial in asymptomatic patients (even with "severe" stenosis by echocardiographic criteria).
the aortic valveThe Aortic valveThe aortic semilunar valve lies between the left ventricle and the aorta.
The heart pumps blood from the left ventricle through the aortic semilunar valve into the Aorta.
The blood flows through the aorta after exiting the left ventricle through the aortic valve.
because the aortic valve is not functioning properly, i.e. prolapse
lol i had the same worksheet. the answer is the aortic valve. i just put down aortic
Aortic valve replacement is necessary when the aortic valve has become diseased. The aortic valve can suffer from insufficiency (inability to perform adequately) or stenosis.

If she is concerned about this she should speak to a physician. Aortic valve replacement may be necessary if her aortic valve has narrowed or is leaking.
The aortic semilunar valve is located between the left ventricle and the aorta.
Aortic stenosis
The Aortic Valve controls the flow of blood from the left ventricle to the aorta.
