It has been shown that increased intracranial pressure in association with neuroborreliosis can lead to blindness. In endemic areas, it is important for practitioners to consider Lyme disease when patients present with persistent headache, especially in those who have evidence of increased intracranial pressure.
The tricuspid valve forms the boundary between the right ventricle and the right atrium. Deoxygenated blood enters the right side of the heart via the inferior and superior vena cava.These are large veins that transport deoxygenated blood from the body back to the heart.ight atrioventricular valve (Tricuspid valve). The tricuspid valve forms the boundary between the right ventricle and the right atrium. Deoxygenated blood enters the right side of the heart via the inferior and superior vena cava. These are large veins that transport deoxygenated blood from the body back to the heart.
The four heart valves are: 1  the tricuspid valve, located between the right atrium and the right ventricle; 2  the pulmonary (pulmonic) valve, between the right ventricle and the pulmonary artery; 3  the mitral valve, between the left atrium and left ventricle; and. 4  the aortic valve, between the left ventricle and the aorta.
