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.
Gross Anatomy. The tricuspid valve is located between the right atrium and right ventricle and has a valve area of 4-6 cm 2 (see the following image and video).The valve is nearly vertical and is approximately 45Â° to the sagittal plane.
