1.5 Minimum Cost Analyses. A similar, but different problem is the determination of the point of minimum total cost. Instead of balancing two methods with different fixed and variable costs, the aim is to bring the sum of two costs to a minimum.
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.
Your tricuspid valve is the valve that separates your right atrium and right ventricle. TR occurs when this valve does not properly close, causing blood to flow back up into the right atrium when the right ventricle contracts.Over time, this condition can weaken your heart.ight Ventricle Dilation. The most common cause of tricuspid regurgitation is right ventricle dilation. The right ventricle (which is the lower right-hand chamber) is responsible for pumping blood from your heart to your lungs.
