Congenital pulmonary stenosis is when the pulmonary valve doesn't fully open. This health problem is present from birth. Congenital pulmonary stenosis surgery aims to fix this problem. It is a type of open heart surgery.

A person with coronary heart disease has an accumulation of fatty deposits in the coronary arteries. These deposits narrow the arteries and can decrease or block the flow of blood to the heart.

A computed tomography (CT) scan is a type of imaging test. It uses X-rays and a computer to make images or slices of the body. A CT scan can make detailed pictures of any part of the body, including the bones, muscles, fat, organs, and ...

Dilated cardiomyopathy, or DCM, is when the heart chambers stretch and become thin. It often starts in the left ventricle. As the disease gets worse, it may spread to the right ventricle and to the atria. As the muscle stretches, it ...

A dobutamine stress echocardiogram is a diagnostic test to assess the heart muscle under stress. If exercise on a treadmill is not an option (too much stress on the heart) due to a person's medical condition, a doctor may use an ...

Detailed information about double outlet right ventricle (DORV), a heart malformation that is present from birth.

An echocardiogram is a noninvasive (the skin is not pierced) procedure used to assess the heart's function and structures.

Eisenmenger syndrome is an advanced form of

Cardioversion is a procedure used to return an abnormal heartbeat to a normal rhythm. This procedure is used when the heart is beating very fast or irregular. This is called an arrhythmia. Arrhythmias can cause problems such as fainting,...

An electrocardiogram (ECG) is one of the simplest and fastest tests used to evaluate the heart. Electrodes (small, plastic patches that stick to the skin) are placed at certain locations on the chest, arms, and legs. When the electrodes ...

An electrophysiologic study uses small, thin wire electrodes placed directly on the heart to evaluate you for an abnormal heart rhythm.

An event monitor is a portable device used to record your heart's electrical activity when you have symptoms. It records the same information as an electrocardiogram (ECG), but for longer durations of time. Most of these devices can ...

An exercise echocardiogram is a procedure in which ultrasound, or sound wave technology, is used to asses the heart's response to stress or exercise.

An electrocardiogram (ECG) is one of the simplest and fastest tests used to evaluate the heart. For this test, electrodes (small, plastic patches that stick to the skin) are placed at certain spots on the chest, arms, and legs. When the ...

Fluoroscopy is a study of moving body structures. It’s much like an X-ray "movie" and is often done while a contrast dye moves through the part of the body being examined. Fluoroscopy, as an imaging tool, allows healthcare providers to ...

A heart attack happens when the blood supply is cut off from the heart muscle, usually because of a blood clot. Without blood and oxygen, the muscle cells are damaged and die.

When you have heart block, there is interference with the electrical signals that usually move from the top chambers of your heart to the bottom chambers, telling your heart when to beat. Read on to learn about causes, symptoms, and ...

Heart failure is a condition in which the heart cannot pump enough blood to meet the body's needs.

Heart failure is when the heart can't pump enough blood to the body. In children, it is often caused by a congenital heart defect.

Heart murmurs may be caused by a number of factors or diseases, including defective heart valves, fever, and pregnancy. Read on to learn more about this condition.

Heart murmurs are extra or unusual sounds made by blood moving through the heart. Many children have heart murmurs. Some cause no problems or go away over time. Others require treatment.

Heart valves can malfunction on one of two ways: They can fail to close completely, allowing blood to flow backward, or they can become damaged, limiting blood flow.

Blood pressure is the force of the blood pushing against the artery walls. High blood pressure (hypertension) means that the pressure inside the arteries is too high. This higher pressure may harm the arteries and cause the heart to work...

High blood pressure, or hypertension, increases the risk for coronary heart disease (heart attack) and stroke (brain attack). Read on for details about this condition.

High blood pressure, or hypertension, increases the risk for coronary heart disease (heart attack) and stroke (brain attack). Read on for details about this condition.

The Holter monitor is a type of electrocardiogram (ECG) used to record an ECG tracing of the heart continuously for 24 hours or longer.

Hypertrophic cardiomyopathy, or HCM, is a disease that causes thickening (hypertrophy) of the heart muscle. The heart cells enlarge more than they should and scarring is often found between the cells.

Hypoplastic left heart syndrome (HLHS) is a group of defects of the heart and large blood vessels. A child is born with this condition (congenital heart defect). It occurs when part of the heart doesn't develop as it should during the ...

Pacemakers and implantable cardioverter defibrillators (ICDs) are heart devices. They are surgically placed in people. Pacemakers are used to treat slow heart rhythms. ICDs stop dangerous
