Recirculation and stagnation zones for different types of valves and control parameters were identified, and the optimal orientation for valves in ventricles was determined. The flow distribution characteristics of a pulsatile blood pump depend on the type and orientation of valves mounted in it. The ...

The risk of reoperative AVR is usually similar to that for primary AVR; in particular, reoperation for tissue valve failure can be performed with a low risk of mortality. Show abstract Factors influencing the mean postoperative gradients across stentless porcine valves 2005, Heart Lung and ...
In the thoracic cavity, how are the heart and lung related to each other? What separates the atria from the ventricles? What organ system does the aorta belong to? What is the main organ of the circulatory system? What valves are located between the atri...

Describe the movement of blood through the heart from the point of entry (of deoxygenated blood) to its destination (as oxygenated blood); include all relevant blood vessels, valves and chambers. Consider drawing a diagram to assist with your explanation. How are the circulatory systems in ani...
In this context, right ventricular (RV) dysfunction has long been disregarded. Cardiac damage from AS might progress to the right heart, resulting in RV remodelling or dilation, potentially disimproving prognosis [5, 6]. However, this con- cept of AS-induced cardiac damage has also been ...
Step-by-Step Solution:1. Understanding the Role of Veins: Veins are blood vessels that carry blood towards the heart. This is an important distinction to make, as they are often confused with arteries, which ca
