Since the valves act as the doors of the heart what might happen if these doors do not close?

The valves have to open to let blood flow into a chamber, and close before the blood flows back. If the valves do not open and close precisely on schedule, or if they fail to open or close completely, the blood will not flow efficiently. This can cause fluctuations in blood pressure, lack of flow to organs, or damage to the muscles of the heart.
For example, if the aortic valve between the heart and the aorta does not close after the left ventricle contracts, there will be back pressure into the ventricle, less blood pumped out of the heart, and lower pressure in the arteries.
