A new ultrasound-based imaging tech has been developed to map the organ blood flow in four dimensions (3D + time) — a level ...

Aortic stenosis is a narrowing of the aortic valve that affects how blood flows through the heart and body. While not often linked to heart valve narrowing, high and irregular blood pressure can ...

Valvular regurgitation is when blood flows backward through the chambers of your heart. It can be mild and not cause symptoms, or it can be life threatening. Your heart is a muscular organ that ...

Heart valves allow blood to flow one way and prevent it from flowing in the wrong direction. The tricuspid valve controls blood flow between the right atrium and right ventricle. The bicuspid or ...

This new imaging technique, when applied to humans, could both improve our understanding of the circulatory system (veins, ...

Vasodilators allow blood to flow more easily through your veins and arteries by relaxing the tiny muscles found in blood vessel walls. Research indicates that ingesting cayenne pepper increases ...

To be able to observe the blood flow in the artificial heart in real time in the MRI, the researchers an Linköping University had to build a full-scale model of the human circulatory system. Using ...

Researchers have developed a method for cheaply producing heart valves in the span of minutes that are functional immediately after being implanted into sheep. The scientists call their method ...
