There are a variety of ways of evaluating a studentâs progress and achievement in the internship. These include an evaluation of work by the on-site supervisor, a studentâs self-evaluation, a visit to the work site by the faculty sponsor, and specific academic requirements fulfilled by the student.
Regurgitation/Insufficiency (leaky valve) - the valve does not close properly and allows blood to flow backward as well as forward in the heart. The valves in your heart may be damaged due to infection, rheumatic heart disease, wear and tear, tissue weakening or deterioration, or birth (congenital) defects.egurgitation/Insufficiency (leaky valve) - the valve does not close properly and allows blood to flow backward as well as forward in the heart.

In mitral valve disease, the mitral valve, which is located between your left heart chambers (left atrium and left ventricle), doesn't work properly. Types of mitral valve disease include:Mitral valve regurgitation. In this condition, the flaps (leaflets) of the mitral valve don't close tightly, causing blood to leak backward into the left atrium of your heart. If not treated, it can result in heart muscle damage.The most common cause of blood leakage is mitral valve prolapse, in which the leaflets bulge back into the left atrium as your heart contracts. 1  Mitral valve stenosis. 2  In this condition, the flaps of the mitral valve become thick or stiff, and they may fuse together.f not treated, it can result in heart muscle damage.
