What is heart failure?

Heart failure happens when the heart can’t pump enough blood to the body’s other organs. The heart still works but not as well as it should.

  • Heart failure can happen at any age and for many reasons. There are 2 main types of heart conditions that may cause heart failure in children: 

    • Congenital defects and other problems with the structures of the heart
    • Problems with the heart muscle 

    Children may be born with these problems, or the problems may develop later in life.

    Birth defects are the most common cause of heart failure in babies and children. Defects like aortic stenosishypoplastic left heart syndromecoarctation of the aortaventricular septal defectatrioventricular septal defect and others sometimes lead to heart failure. They can cause heart failure because they cause problems with blood flow into, out of or within the heart.

    Diseases of the heart muscle, such as myocarditis or cardiomyopathy, may also cause heart failure. These diseases can make the heart muscle unable to pump the way it should. Heart failure can happen if the heart beats too fast or too slow.

    Heart failure may also happen after open-heart surgery to repair birth defects. This may last only for days, or it may last for months or years. In some cases, it may be permanent. 

  • Heart failure can lead to different problems, depending on the cause. 

    • If the left ventricle can’t pump well, blood flow from the heart to the body may be slow. This can make fluid back up in the lungs, causing breathing problems. It can also cause problems with other organs, like the kidneys or intestines, if they don’t get enough blood.
    • If the right ventricle can’t pump well, blood flow from the heart to the lungs may be slow. This can make fluid back up in the tissues, which can appear as edema of the body or swelling of the liver.

Heart Failure at Seattle Children’s

Consistently ranked one of the nation's best cardiology and cardiac surgery programs by U.S. News and World Report.Seattle Children’s Heart Failure Program is the only one in the Pacific Northwest with the depth of expertise to offer every type of therapy for heart failure in children. We have the medical and surgical expertise, and the latest technology, to handle the most complex cases.

What are the symptoms of heart failure?

Some of your child’s symptoms may depend on whether the left side, right side or both sides of the heart are affected.

  • These are symptoms of heart failure in babies: 

    • Not gaining weight
    • Sweating when drinking from a bottle or sleeping
    • Tires easily when drinking from a bottle
    • Not able to finish a bottle
    • Coughs, especially when lying down
    • Difficulty breathing or breathing harder and faster than normal
    • Being more irritable
  • Young children with heart failure tend to have problems with being very tired (fatigued), even with normal activity, and looking or feeling short of breath.

    Children may also have these symptoms: 

    • Not wanting to eat much
    • Stomach pain, bloating or feeling very “full”
    • Not able to keep food down
    • Vomiting more than 2 times in 24 hours
    • Cough, especially at night
    • Difficulty sleeping or lying flat
    • Swelling around eyes, face or ankles
    • Difficulty learning at school due to being tired
    • Not able to gain weight, or may lose weight

How is heart failure diagnosed?

To diagnose this condition, your child’s doctor will examine your child thoroughly. This includes using a stethoscope to listen to their heart and checking their breathing and blood pressure.

The doctor will ask for details about your child’s symptoms, their health history and your family health history.

Chest X-rayselectrocardiography and echocardiography can provide more information about how your child’s heart looks and works.

To tell what caused your child’s heart failure, the doctor may need to do other procedures, such as an MRI (magnetic resonance imaging) of their heart or a cardiac catheterization.

How is heart failure treated?

Treatment for heart failure depends on the cause. Doctors use many different treatments to lower the workload of the heart. The goals are to control extra fluid and improve the heart’s ability to pump.

Doctors also try to find and treat any condition that caused the heart failure. Some children need treatments for a related condition, such as surgery to repair a heart defect or medicine for arrhythmia.

Your child may need 1 or more of these types of care:

  • Our doctors are able to control many types of heart failure with medicines to help your child’s heart work better.

    Diuretics help the kidneys rid the body of extra water. This lowers the amount of fluid in the lungs and improves circulation.

    Other medicines are used to help the heart heal so it can function better.

  • If your child was born with complex heart disease, they may be at risk for problems with how their brain and central nervous system grow and develop.

    We work closely with Seattle Children’s Cardiac Neurodevelopmental Clinic to understand and meet your child’s needs. The clinic evaluates and treats babies and children with complex congenital heart defects who had heart surgery before their first birthday. We provide close follow-up during their first 3 to 5 years of life.

    A visit to the Cardiac Neurodevelopmental Clinic can reassure you that everything is normal with your child’s brain and nervous system. If we find developmental issues, we help connect you with therapies that make a difference for your child.

  • If a slow heartbeat caused your child’s heart failure, the doctor may recommend putting in a pacemaker. Pacemakers help your child’s heart maintain a normal rate. These small, battery-operated devices are like tiny computers. Doctors place them inside your child’s chest. A tiny wire connects the pacemaker to your child’s heart.

    Read about what to expect with a pacemaker.

  • If your child’s heart failure happened because their ventricles do not beat in time with each other the way they should, the doctor may recommend CRT. It uses a special kind of pacemaker. Doctors place a small, battery-operated device under your child’s skin. Tiny wires connect the device to your child’s ventricles and signal them to work in a coordinated way.

  • If a birth defect caused your child’s heart failure, they may need surgery.

    Many heart surgeries are done to make the flow of blood through the heart as normal as possible so a child can live a long and active life. Babies born with complex heart defects need various surgeries, sometimes over several years, for their heart to work the best that it can. Our pediatric heart surgeons use the most advanced techniques and achieve results that are among the best in the nation.

    Learn more about heart surgery at Seattle Children’s.

  • Some children need more than medicines to help the heart pump. For some of these children, a VAD can help. A VAD is a mechanical pump that a surgeon implants inside or outside your child’s chest. The surgeon connects the pump to your child’s heart during open-heart surgery. Because Seattle Children’s offers many types of VADs, including newer options not available at every hospital, we can choose the device that’s best for your child.

    Most children who receive a VAD will be listed for a heart transplant.

    Read more about VADs at Seattle Children’s.

  • If other treatments cannot control your child’s heart problems, your child may need a heart transplant. Seattle Children’s heart transplant team does an average of 18 transplants each year in babies, children, teens and young adults through age 21.

    Our transplant outcomes (survival rates) are among the best in the nation year after year. See our statistics.

    Adrian Peterson.jpg “I can’t imagine getting any better care than what Adrian had at Seattle Children’s. Each team was always extremely helpful and informative. We knew exactly what was going on from an hour-to-hour, day-to-day basis.”
    — Earl Peterson, whose son Adrian received a ventricular assist device and heart transplant at Seattle Children’s

Who is on the Heart Failure Program team?

Our Heart Failure Program includes highly skilled pediatric cardiologists, pediatric heart surgeons and nurse coordinators who specialize in heart failure and cardiomyopathy.

Research and Clinical Trials

Our physician-scientists study better ways to manage heart failure in children, including:

  • Studying heart failure medicines used in adults to see if they can help children
  • Creating tests to help diagnose heart failure and check a child’s health over time
  • Finding ways to prevent deaths from sudden, unexpected cardiac arrest
  • Developing ways to protect the heart and kidneys from harm during surgery
  • Studying diseases and health problems that happen at the same time as heart failure
