If the valve sticks open, the first thing you will probably experience is shortness of breath. Your blood pressure will be excessively low you'll feel weak and like your going to pass out. If your not on blood thinners there's a good chance a clot could form in the aorta which could cause a stroke. The pooling blood also can cause an infection within the heart which would have to be addressed before corrective surgery. This problem is primarily seen in the older mechanical valve replacements where the patient is already on thinners which takes one of the hazards away from this problem. These patients are generally to weak to go to far except the ER and back on their feet within 10 days after replacement. Native valves generally get stuck open because of stenosis on the leafs which interferes with it's closing most know they had a problem prior to their trip to the ER. If you feel weak or short of breath it's always a good idea to get it checked out ignoring it just makes matters worst. Death is a rare bird today because of this problem but can happen. Modern surgery has made this problem fixable so don't wait if your feeling bad.
ventricular diastole after the aortic valve has closed.
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 pulmonary valve is also known as the pulmonic valve, and the aortic valve is simply referred to as the aortic valve.
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
Aortic valve stenosis can occur because of a birth defect in the formation of the valve. Calcium deposits may form on the valve with aging, causing the valve to become stiff and narrow. Stenosis can also occur as a result of rheumatic fever.

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.
The Aortic Valve controls the flow of blood from the left ventricle to the aorta.
lol i had the same worksheet. the answer is the aortic valve. i just put down aortic
