Heart failure (also called congestive heart failure) occurs when the heart is not able to pump enough blood to the other organs in the body. The heart continues to beat, but it pumps a smaller amount of blood. When the blood cannot move forward, it causes a back-up and collects in the lungs, veins and liver.
The effects of heart failure vary, depending on which part of the heart is affected. Heart failure can affect the right side, the left side, or both sides of the heart.
When the right side of the heart is affected, the heart cannot effectively pump blood into the lungs, and a back-up of blood accumulates in the liver and veins. This can cause fluid retention and you may notice swelling in your child’s face, eyelids, legs, ankles or abdomen.
Heart failure that affects the left side of the heart can strain the rest of the body, including the lungs. When the heart cannot pump blood out to the other organs, the blood backs up in the vessels of the lungs, causing lung congestion. Children may experience difficulty breathing and may breathe faster. Because blood is not efficiently reaching the rest of the body, children often become fatigued (tired) and may have a decreased rate of growth.
Children suffering from heart failure may show some of the following signs:
There are 2 main causes of heart failure in children:
There are several different types of congenital heart defects that cause heart failure. These defects include structural problems that prevent the blood from moving through the heart efficiently. Instead, the blood has to move through alternative pathways, which results in a smaller amount of blood reaching the other organs.
When the muscle material in the heart thickens, it does not function well. A thick muscle reduces the amount of blood the heart can pump. When this happens, the heart cannot supply the body with enough blood to function properly.
If your child is experiencing symptoms of heart failure, or if the physician notices something abnormal during a physical exam, they may recommend additional testing. Sometimes the physician may hear extra sounds, called a heart murmur, when they listen to your child’s heart with a stethoscope.
The following tests may be used:
Electrocardiogram (EKG or ECG) is a painless exam that checks the heart’s electrical activity. The exam can detect damage or irregular heart rhythms that may indicate the right ventricle is not functioning properly.
These images are used to look at the heart and lungs. If the right side of the heart is enlarged, it may indicate an atrial septal defect (ASD), which is a hole in the wall between the two upper chambers of the heart.
Sound waves are used to produce images of the heart and vessels on a computer screen. This exam can determine whether or not the heart is pumping properly. It can also identify an atrial septal defect (ASD).
This exam uses radio waves, magnets and a computer to create three-dimensional images of the heart. It can reveal structural abnormalities, like an enlarged right ventricle, that can be caused by an atrial septal defect (ASD).
Thin, long tubes are inserted into blood vessels and guided into the heart, with the help of fluoroscopy (X-ray), to look for abnormalities.
Treatment for heart failure depends on the severity of the condition. Many children with mild heart failure can be managed with medications and live normal lives. More advanced cases of heart failure may require a hospital stay with IV medications to support the heart.
When a child has severe heart failure, they may require a life-saving procedure. One option is a heart transplant. Another option is a Ventricular Assist Device (VAD), which is a mechanical pump to help the heart pump blood to the rest of the body.
The Children’s Heart Institute at Children’s Memorial Hermann Hospital specializes in all levels of treatment for congestive heart failure, from mild to severe. Our heart-transplant and VAD teams are prepared to care for your child’s long-term needs so they can live a better life.
At Children’s Heart Institute at Children’s Memorial Hermann Hospital, patients with congenital or acquired heart disorders receive hands-on specialized care 24/7 from a team of affiliated physicians and specialty-trained nurses who aim to deliver the best possible outcomes.
Children’s Memorial Hermann Hospital was named one of the top 25 best children's hospitals nationally in Cardiology & Heart Surgery by U.S. News & World Report. In addition, Children’s Heart Institute is among the elite top 6% of congenital heart surgery programs in the Unites States and Canada for patient care and outcomes, according to the Fall 2019 Society of Thoracic Surgeons (STS) Congenital Heart Surgery Database Report of 118 STS participating programs.
In collaboration with various subspecialties, the affiliated team provides comprehensive care for newborns, children and adolescents, with the ability to transition into adult congenital cardiac care. Team members have the experience and skills necessary to offer innovative treatment methods and specialized services, including, but not limited to:
