    Cardiomyopathy

    The interior of the heart is composed of valves, chambers, and associated vessels.

    Cardiomyopathy is disease in which the heart muscle becomes weakened, stretched, or has another structural problem. It often occurs when the heart cannot pum...

    Dilated cardiomyopathy

    The interior of the heart is composed of valves, chambers, and associated vessels.

    Dilated cardiomyopathy is a condition in which the heart becomes weakened and enlarged. As a result, the heart cannot pump enough blood to the rest of the bo...

    Echocardiogram

    Blood used by the body is brought back to the heart and lungs by the veins of the body.  Once the blood has gathered more oxygen from the lungs, it is pumped back out to the  body through the arteries.

    An echocardiogram is a test that uses sound waves to create pictures of the heart. The picture is more detailed than a standard x-ray image. An echocardiogra...

    Heart Failure Overview

    The interior of the heart is composed of valves, chambers, and associated vessels.

    Heart failure is a condition in which the heart is no longer able to pump out enough oxygen-rich blood. This causes symptoms to occur throughout the body. He...

    Heart MRI

    The interior of the heart is composed of valves, chambers, and associated vessels.

    Heart magnetic resonance imaging (MRI) is an imaging method that uses powerful magnets and radio waves to create pictures of the heart. It does not use radia...

    Hypertrophic cardiomyopathy

    The interior of the heart is composed of valves, chambers, and associated vessels.

    Hypertrophic cardiomyopathy (HCM) is a condition in which the heart muscle becomes thick. Often, only one part of the heart is thicker than the other parts. ...

    Left heart ventricular angiography

    Left heart ventricular angiography is a procedure to look at the left side of the heart and, sometimes, the coronary arteries. Before the test, you will be g...

    Nuclear ventriculography

    The external structures of the heart include the ventricles, atria, arteries and veins. Arteries carry blood away from the heart while veins carry blood into the heart. The vessels colored blue indicate the transport of blood with relatively low content of oxygen and high content of carbon dioxide. The vessels colored red indicate the transport of blood with relatively high content of oxygen and low content of carbon dioxide.

    Nuclear ventriculography is a test that uses radioactive materials called tracers to show the heart chambers. The procedure is noninvasive. The instruments d...

    Pulmonary edema

    Air is breathed in through the nasal passageways, travels through the trachea and bronchi to the lungs.

    Pulmonary edema is an abnormal buildup of fluid in the lungs. This buildup of fluid leads to shortness of breath. Pulmonary edema is often caused by congesti...

    Restrictive cardiomyopathy

    The interior of the heart is composed of valves, chambers, and associated vessels.

    Restrictive cardiomyopathy refers to a set of changes in how the heart muscle functions. These changes cause the heart to fill poorly (more common) or squeez...

    Right heart ventriculography

    The interior of the heart is composed of valves, chambers, and associated vessels.

    Right heart ventriculography is a study that images the right chambers (atrium and ventricle) of the heart. You will get a mild sedative 30 minutes before th...

    Sodium in diet

    Sodium is an element that the body needs to function properly to regulate blood pressure and blood volume. For individuals who are sodium-sensitive, an increased intake of sodium may contribute to high blood pressure. When watching the intake of sodium, read labels carefully to determine the total sodium content. Canned, packaged, and frozen foods can be particularly high in sodium.

    Sodium is an element that the body needs to work properly. Salt contains sodium. The body uses sodium to control blood pressure and blood volume. Sodium is ...

    Ventricular assist device

    The interior of the heart is composed of valves, chambers, and associated vessels.

    Ventricular assist devices (VADs) help your heart pump blood from one of the main pumping chambers to the rest of your body or to the other side of the heart...
