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 ...

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.

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.

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.

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 ...

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 ...

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.

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.

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...

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 ...

Marfan Syndrome in Children

Marfan syndrome is a genetic disorder that affects the body's connective tissue. Connective tissue holds the body's cells, organs, and other tissue together. Connective tissue is also important in growth and development.

Pericarditis in Children

Pericarditis is inflammation or infection of the pericardium. In children, pericarditis is most likely to happen after surgery to repair heart defects.

Persistent Pulmonary Hypertension in the Newborn

Persistent pulmonary hypertension (PPHN) happens in newborn babies. It occurs when a newborn’s circulation changes back to the circulation of a fetus. When this happens, too much blood flow bypasses the baby’s lungs. This is sometimes ...

Rheumatic Heart Disease in Children

Rheumatic heart disease is a condition that causes permanent damage to the heart valves.

Tetralogy of Fallot (TOF)

Tetralogy of Fallot is 4 congenital heart defects. This means that your child is born with them. These 4 problems occur together (tetralogy refers to 4).

Total Anomalous Pulmonary Venous Return (TAPVR)

Total anomalous pulmonary venous return (TAPVR) is a congenital heart defect. This means that your child is born with it. It happens as the baby’s heart develops during the first 8 weeks of pregnancy.

Tricuspid Atresia

Tricuspid atresia (TA) is a heart defect present at birth (congenital). It occurs when the tricuspid valve doesn’t form right during fetal heart development. This happens during the first 8 weeks of pregnancy. The tricuspid valve is ...

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 ...

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.

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 ...

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.

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 ...

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 ...

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 ...

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.

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...

Mitral Valve Regurgitation

Mitral valve regurgitation is when the mitral valve in the heart is leaky. It’s also known as mitral insufficiency. The mitral valve is one of the heart’s four valves. These valves help the blood flow through the heart’s four chambers ...

Mitral Valve Prolapse

The mitral valve sits between the left atrium and left ventricle. It's job is to keep blood flowing in the right direction. Mitral valve prolapse is the bulging of the valve causing blood to leak backwards.

Pericardial Effusion

Pericardial effusion is the buildup of extra fluid in the space around the heart. If too much fluid builds up, it can put pressure on the heart. This can prevent it from pumping normally.

Patent Foramen Ovale

A patent foramen ovale (PFO) is a small hole between the two upper chambers of the heart, the right and the left atrium. Normally, a wall separates these chambers. No blood can flow between them. If a PFO exists, a little blood can flow ...
