A
Angina Pectoris

Angina pectoris—or simply angina—is chest pain or discomfort that keeps coming back. It happens when some part of your heart does not get enough blood and oxygen.

Anomalous Coronary Artery in Children

An anomalous coronary artery (ACA) is a heart defect. This is something your baby is born with (congenital). In ACA, the blood vessels that supply blood to your child’s heart muscle aren’t normal.

Aortic Stenosis in Children

Aortic stenosis means that your child has a heart valve that is too narrow or is blocked. The aortic valve is 1 of 4 heart valves that keep blood flowing through the heart. The valves make sure blood flows in only one direction. The ...

Aortic Valve Regurgitation

Aortic valve regurgitation is when a person’s aortic valve leaks. The aortic valve is one of the heart’s 4 valves. These valves help the blood flow through the heart and out to the body. Normally, the aortic valve stops blood from ...

Arrhythmias

An arrhythmia is an abnormal heart rhythm that can cause problems with the contractions of your heart chambers.

Arrhythmias in Children

An arrhythmia is an abnormal rhythm of the heart. In an arrhythmia, abnormal electrical signals through the heart muscle may cause the heart to beat too fast (tachycardia), too slow (bradycardia), or irregularly.

Arrhythmogenic Right Ventricular Dysplasia

Arrhythmogenic right ventricular dysplasia (or ARVD) is a disease of the heart muscle. In this disease, fatty fibrous tissue replaces normal heart muscle. This interrupts normal electrical signals in the heart and may cause irregular and...

Atherosclerosis

Atherosclerosis is a type of thickening or hardening of the arteries caused by a buildup of plaque in the inner lining of an artery. It can increase your risk of heart attack, stroke, and other circulatory conditions.

Atrial Fibrillation

Atrial fibrillation, or AFib, is a kind of abnormal heart rhythm or arrhythmia. AFib increases the risk for blood clots. These clots can then travel to the brain, causing a stroke. This is why AFib significantly increases the risk for ...

Atrial Flutter

Atrial flutter is an abnormal heart rhythm that causes the atria to beat more quickly than they should.

B
Bacterial Endocarditis in Children

Bacterial endocarditis is an infection of the lining of the heart (endocardium), and the heart valves. It does not happen very often, but when it does, it can cause serious heart damage.

Bacterial Endocarditis: Adult

Bacterial endocarditis is a bacterial infection of the inner layer of the heart or the heart valves. The heart has 4 valves. These valves help the blood flow through the heart and out to the body. When a person has bacterial ...

Bicuspid Aortic Valve

Bicuspid aortic valve is a type of abnormality in the aortic valve in the heart. In bicuspid aortic valve, the valve has only two small parts, called leaflets, instead of the normal three. This condition is present from birth. It often ...

Brugada Syndrome

Brugada syndrome is a genetic disorder that causes an irregular heartbeat. This rare, but life threatening condition is more common in people of Asian descent.

Bundle Branch Block

A bundle branch block is an interruption of the electrical pathways inside the wall of the heart. A block in the right bundle branch can occur in people who otherwise seem normal. If it happens with a heart attack, it can be a sign of ...

C
Cardiac Tamponade

Cardiac tamponade happens when extra fluid builds up in the space around the heart. This fluid puts pressure on the heart and prevents it from pumping well.

Catecholaminergic Polymorphic Ventricular Tachycardia

Catecholaminergic polymorphic ventricular tachycardia, or CPVT, is a rare genetic condition. It causes an irregular heart rhythm that can be life threatening. It often shows up in childhood. The first sign is often fainting or near ...

Coarctation of the Aorta (COA) in Children

Coarctation of the aorta is a heart defect that is present at birth (congenital). It means the aorta is narrower than it should be.

D
Dilated Cardiomyopathy

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 ...

Double Outlet Right Ventricle in Children

Double outlet right ventricle (also known as DORV) is a type of heart malformation. It is present from birth (congenital heart defect). It’s when the heart and the main vessels leaving the heart do not develop the right way, leading to ...

E
Eisenmenger Syndrome in Children

Eisenmenger syndrome is an advanced form of pulmonary artery hypertension. In this condition, the arteries that carry blood from the heart to the lungs narrow. This makes the pressure of blood flow against the walls of the arteries ...

H
Heart Block

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.

Heart Failure in Children

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 in Children

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.

High Blood Pressure in Children and Adolescents

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...

Hypertrophic Cardiomyopathy

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) in Children

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 ...

I
Inappropriate Sinus Tachycardia

Inappropriate sinus tachycardia (IST) is a health problem in which the heart beats very quickly without a good reason. It is a type of heart rhythm abnormality called an arrhythmia.

K
Kawasaki Disease

Kawasaki disease causes inflamed blood vessels. It can weaken the walls of blood vessels, including the arteries of the heart. Kawasaki mostly affects infants and young children. It is uncommon in the U.S.

L
Left Bundle Branch Block

In left bundle branch block, there is a problem with the left branch of the electrical conduction system. The electrical signal can’t travel down this path the way it normally would. The signal still gets to the left ventricle, but it is...
