Caring Hearts
Clear, compassionate information for parents whose child has a heart defect or
may need a heart transplant
A note for families:
This website is written for parents and caregivers. It
offers educational and emotional support, but it does not replace guidance
from your child’s medical team.
What are Congenital Heart Defects?
Congenital heart defects (CHDs) are structural problems with the heart that are
present at birth. These differences can affect how blood flows through the heart
and to the rest of the body.
Some heart defects are mild and only need regular checkups. Others are more
complex and may require medications, surgeries, or ongoing specialized care.
Learning that your child has a heart defect can be overwhelming. Feelings of fear,
confusion, sadness, or uncertainty are very common — and you are not alone.
Common Types of Heart Defects
Some of the more common congenital heart defects include:
• Ventricular Septal Defect (VSD) – a hole between the lower chambers of the
heart
• Atrial Septal Defect (ASD) – a hole between the upper chambers
• Tetralogy of Fallot – a combination of four heart abnormalities
• Hypoplastic Left Heart Syndrome (HLHS) – underdevelopment of the left
side of the heart
• Transposition of the Great Arteries – the major blood vessels are switched
Your child’s cardiologist will explain exactly how your child’s heart is affected and
what that means for day‑to‑day life.
Why Medications Are Often Needed
Medications do not usually “cure” a heart defect, but they play an essential role in
helping children live healthier, more comfortable lives. Medications may:
• Reduce symptoms such as shortness of breath or swelling
• Help the heart pump more effectively
• Prevent complications like heart failure, abnormal heart rhythms, or blood
clots
• Support children before surgery or during recovery afterward
Many children with heart defects take medications long‑term, and some continue
them into adulthood. Treatment plans are individualized and may change as your
child grows.
Common Medications For CHD's
Diuretics (“Water Pills”)
What they do: Help remove excess fluid from the body, reducing strain on the
heart
Why they are used: Fluid buildup can cause swelling and breathing difficulties
Examples: Furosemide (Lasix), Spironolactone
Possible side effects: Dehydration, low potassium levels
ACE Inhibitors and ARBs
What they do: Lower blood pressure and make it easier for the heart to pump
Why they are used: Help manage heart failure and improve blood flow
Examples: Lisinopril, Enalapril, Losartan
Possible side effects: Dizziness, cough, kidney issues
Beta Blockers
What they do: Slow the heart rate and reduce the heart’s workload
Why they are used: Control abnormal heart rhythms and heart failure
Examples: Metoprolol, Atenolol, Carvedilol
Possible side effects: Fatigue, low heart rate
Antiarrhythmic Medications
What they do: Help regulate irregular heartbeats
Why they are used: Heart defects can interfere with the heart’s electrical system

Examples: Amiodarone, Digoxin, Sotalol
Some of these medicines require close monitoring due to potential side effects.
Anticoagulants (“Blood Thinners”)
What they do: Prevent dangerous blood clots
Why they are used: Especially important for children with artificial heart valves or
certain surgeries
Examples: Warfarin, Aspirin, Heparin
Important to know: These medications increase bleeding risk and require careful
monitoring.
Understanding Heart Transplants
In some cases, surgeries and medications are not enough to support a child’s
heart. When this happens, a heart transplant may be recommended.
A heart transplant replaces a failing heart with a healthy donor heart. This is a
major procedure followed by lifelong care. Children who receive transplants take
medications every day to prevent rejection and are closely followed by a
specialized transplant team.
While the journey is challenging, many children go on to attend school, play, and
grow after transplantation.
Lifelong Care and Monitoring
Even after successful surgery or a transplant, most children with heart conditions
are not considered “cured.” Ongoing care is important and usually includes:

• Regular cardiology appointments
• Medication adjustments over time
• Monitoring for complications as your child grows
As children become adults, many transition to Adult Congenital Heart Disease
(ACHD) specialists who understand their unique needs.
Support Systems
Supporting Your Family
Caring for a child with a heart condition affects the entire family. Parents may
experience emotional stress or exhaustion, and siblings may also need support
and reassurance.
It is okay to ask for help. Hospital social workers, counselors, and parent support
groups can make a meaningful difference.
