Wk 2 Case Study Heart 1.
Heart valves include the tricuspid, mitral, pulmonary, and aortic semilunar valves. The tricuspid valve connects the right atrium and right ventricle. This valve helps deoxygenated blood flow from the right atrium to the right ventricle. The mitral (bicuspid) valve links the left atrium to the left ventricle. The pulmonary semilunar valve connects the right atrium to the pulmonary trunk. Between the left ventricle and aorta is the vital aortic semilunar valve.

Mitral valve prolapse, also known as Barlow syndrome, is a type of
heart valve disease
in
which the flaps (also called leaflets or cusps) of the mitral valve become enlarged or stretched. These enlarged flaps bulge (prolapse) into the left atrium as the heart contracts with each heartbeat (Penn Medicine, 2023). The hereditary condition Marfan syndrome affects connective tissue, which supports the body and organs. Marfan syndrome can cause structural harm to the body. It presents a variety of tolerable symptoms. Patients may experience cardiac problems, scoliosis, vision problems, malocclusion, and pneumothorax.

When the left ventricle contracts, the mitral valve's two flaps might prolapse into the left atrium. This medical condition is known as mitral valve prolapse (MVP). This particular incident has the potential to obstruct the valve's ability to close completely. Blood regurgitation from the ventricle into the atrium may occur in cases of mitral valve
prolapse. Heart valve diseases, commonly known as infective endocarditis, and probable changes in heart dimensions are among the many consequences of regurgitation.
5.
The tricuspid valve serves as a structural boundary between the right atrium and right ventricle. As a result, patients with tricuspid valve prolapse may have difficulty achieving
proper closure of the tricuspid valve. It is possible for blood to flow retrogradely towards the right atrium during right ventricle contraction. In the long run, this could have a variety of impacts on the heart, including an impact on myocardial contractility.

Janet will no longer be able to participate in basketball activities safely, in my opinion. Even with treatment, she may be severely harmed in the future. Due to the high-intensity nature of basketball, this will place an undue strain on the heart system as a result of the body's increased demand for oxygen. This circumstance, I feel, exemplifies negative feedback.
