>>>>Mitral valve regurgitation indicates the one-way valve that separates the upper chamber (atrium that receives blood from the lungs) and the lower heart chamber that pumps blood into circulation is permitting blood to go back into the upper chamber.  If the mitral valve leaflets that closes and prevents back flow is not compliant, blood will flow back into the upper chamber.  Also, if the valve opening could become calcified as well as the leaflets that can cause back flow problems as well, etc. And the cords that attach hinge like to the leaflets can be elongated and the leaflets bellow back into the upper atrium when there is pressure from the lower chamber.  This disorder is medically reffered to as mitral valve prolapse.  Can be congenital and usually does not progress or cause problems because the leakage is mild.

Tricuspid valve has 3 cuspids (leaflets) that separates the rightside's upper chamber (atrium) and lower chamber (ventricle).  Because the rightside does not have very high intra-chamber pressures, the same problems don't exist for the valve, but there can be leakage from calcification, etc.  

Hope this helps provide some insight, if not please feel free to ask any follow up questions..  Thank you for sharing.
