Patient was educated on left heart and the valves on the left heart as follows:

1. The oxygenated blood from the lungs, through pulmonary veins, will enter the left heart, into the left atrium.
2. This blood in the atrium will be pumped into the left ventricle through a valve (left atrioventricular valve, also called bicuspid valve).
3. As soon as, the blood moves from the left atrium into the left ventricle, the valve between these chambers will close to prevent any reverse flow from the left ventricle into the atrium.
4. The oxygenated blood from left ventricle is pumped into the aorta, through a valve, aortic valve, which allows flow only from the left ventricle into the aorta, which carries the blood to all the different organs in the body, through the arterial system.
5. As soon as, the blood moves from the left ventricle into the aorta, the aortic valve will close to prevent any reverse flow, from the aorta back into the left ventricle.
