Heart Valve Diseases

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.

High Blood Pressure in Children and Teens

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/Hypertension

High blood pressure, or hypertension, increases the risk for coronary heart disease (heart attack) and stroke (brain attack).

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 ...

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.

Kawasaki Disease in Children

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.

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...

Long QT Syndrome

Long QT syndrome can cause life threatening rapid heart rhythms that can lead to fainting or sudden death.

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.

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.

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 ...

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. Here's what you need to know.

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.

Pericarditis

Pericarditis is inflammation of the pericardium, the thin sac that surrounds the heart.

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 ...

Premature Ventricular Contractions

Premature ventricular contractions, or PVCs, are a type of abnormal heartbeat. Your heart has 4 chambers: 2 upper atria and 2 lower ventricles. Normally, a special group of cells begin the signal to start your heartbeat. These cells are ...

Restrictive Cardiomyopathy

Restrictive cardiomyopathy, or RCM, is when the chambers of the heart become stiffer over time. Though the heart is able to squeeze well, it is not able to relax between beats normally. This makes it harder for the heart to fill with ...

Rheumatic Heart Disease

Rheumatic heart disease is a condition where the heart valves have been permanently damaged by rheumatic fever.

Rheumatic Heart Disease in Children

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

Right Bundle Branch Block

Right bundle branch block comes from a problem with the heart's ability to send electrical signals. It usually doesn't cause symptoms unless you have some other heart condition.

Sick Sinus Syndrome

Sick sinus syndrome is a type of abnormal heartbeat, or arrhythmia. If you have sick sinus, you may have episodes when your heart beats very slowly, stops beating for a short while, or beats very rapidly.

Sinus Bradycardia

Sinus bradycardia is a type of slow heartbeat. A special group of cells begin the signal to start your heartbeat. These cells are in the sinoatrial (SA) node. Normally, the SA node fires at about 60 to 100 times per minute at rest. In ...

Supraventricular Tachycardia

Supraventricular tachycardia (SVT) is a kind of abnormally fast heartbeat.

Syncope in Children

Syncope is a brief loss of consciousness and muscle tone caused when not enough blood gets to the brain. Syncope is commonly called fainting. In most children, it’s usually harmless. But in a few children, syncope is serious. This is ...

Takotsubo Cardiomyopathy

Takotsubo cardiomyopathy (TCM) is a type of heart condition. It causes sudden chest pain. The symptoms of TCM can look like a heart attack.

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 ...
