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.

Valvular heart disease is characterized by damage to or a defect in one of the four heart valves: the mitral, aortic, tricuspid or pulmonary. The mitral and tricuspid valves control the flow of blood between the atria and the ventricles (the upper and lower chambers of the heart). High blood pressure and atherosclerosis may damage the aortic valve. 2  A heart attack may damage the muscles that control the heart valves. 3  Other disorders such as carcinoid tumors, rheumatoid arthritis, systemic lupus erythematosus, or syphilis may damage one or more heart valves.
