The film presents a detailed fluorographic study of the normal heart using venous catheterization, showcasing physiological data such as pressure and flow measurements. It illustrates blood flow ...

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 ...

An aortic stenosis murmur is an unusual sound the heart makes due to a narrowing of the aortic heart valve. The narrowed heart valve restricts blood flow from the heart, which can create a murmur.

Heart valve diseases affect how blood flows through the heart muscle. Not all people experience symptoms, even if the condition is severe. You may recognize these early signs and symptoms of heart ...

New technology can detect rapid pressure changes inside your heart. The state-of-the-art technology uses magnetic resonance imaging (MRI) to create detailed images of the heart. Using the new ...

Researchers at the University of East Anglia have used cutting-edge imaging technology to measure acute pressure changes inside the heart. The state-of-the-art technology uses magnetic resonance ...

Uncontrolled or undetected high blood pressure, also called hypertension, is one of the most concerning precursors to heart problems. Because hypertension damages one's arteries and decreases the flow ...

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 ...
