Your child's heart surgery is one of the most intense experiences a parent can face. Months of waiting, diagnosis, consultations, decisions — and finally the day of surgery arrives. You wait. Hours pass. The surgeon walks out and says: "Everything went well."
You were ready for that moment. But what comes next — most parents haven't fully thought through.
Once the operation is behind you, the real question emerges: what does life look like now?
This guide is written to answer exactly that. Discharge from hospital, the first weeks at home, medication schedules, school, sports, emotional recovery — all of it, step by step.
Immediately after surgery: what happens in the ICU?
After the operation, your child goes directly to the intensive care unit. This is the moment that causes the most anxiety for parents — you can't see your child, there are machines everywhere, staff constantly coming and going.
Stay calm. This is standard procedure.
Children typically spend 1-3 days in the ICU. During this time, heart rate, blood pressure, and oxygen levels are continuously monitored. When your child wakes up, they may not understand what's happening — your presence, a hand to hold, a familiar voice is enough. Pain is managed professionally — modern protocols ensure children do not suffer. An breathing tube (intubation) may be in place in the first hours — this is a normal part of the surgery and is usually removed within 12-24 hours. Drainage tubes remove fluid from the chest cavity and are typically taken out after 1-2 days.
Parents can usually see their child 2-4 hours after surgery. Rules vary between hospitals — discuss this with your surgeon in advance.
Total hospital stay depends on the complexity of the procedure. After simpler operations, discharge may happen in 5-7 days. More complex surgeries may require 2-3 weeks.
Coming home: what to expect
Going home is a tremendous relief. At the same time, many parents feel lost in the first few days. In hospital, doctors were always nearby — now you're on your own.
In reality, you are ready. You just need to know what to watch for.
Wound care. The surgical scar on the chest can look alarming at first. With proper care, it fades significantly over time. Check the wound daily — keep it dry and clean. For the first week, sponge baths are recommended instead of showering. If you notice redness, swelling, warmth, discharge, or the wound edges separating — contact your doctor immediately. Choose soft, non-restrictive clothing. For the first year, keep the scar covered in the sun — otherwise it may darken permanently.
Sternal healing. This is the most important restriction, and one many parents aren't aware of. During surgery, the breastbone (sternum) is opened and then wired shut. Full healing takes 6-8 weeks. During this time, do not lift your child by the armpits. When picking them up, slide your hands under their back and bottom. For older children — pulling by the arms, lifting under the arms, swinging — is not allowed. Every family member, as well as teachers and nursery staff, should be aware of this.
Medications: the most important topic
After surgery, your child may be prescribed several medications — to regulate heart rhythm, prevent blood clots, or maintain fluid balance.
Give medications at the exact times prescribed — missing by an hour once is not critical, but consistent delays are. Do not stop medications on your own, even if your child feels well. Don't add any other medicines without your doctor's approval — even a common cough syrup can interact. Write out a medication schedule and put it somewhere visible. If you miss a dose — call your doctor rather than making the decision yourself.
Nutrition: what to expect
Loss of appetite after surgery is normal. Especially in the first week, your child may eat very little — don't panic. Offer small, frequent meals, let them choose what they'd like, and don't turn mealtimes into a battle.
In infants, the sucking reflex may temporarily weaken after surgery — a lactation consultant can help. Salt restriction is sometimes recommended — check with your doctor.
When your child starts gaining weight again — that's a reliable sign recovery is going well.
Emotional recovery: the unexpected side
Physical recovery is visible — the wound heals, strength returns. Emotional recovery is hidden, and often noticed only when it's been going on a while.
Hospital fear. Seeing a doctor, a white coat, or a needle may make your child cry or try to run away. This is a trauma response. Don't force it — it fades with time.
Regression. A child of 5 or 6 may suddenly act like a toddler — sucking their thumb, wetting the bed, refusing to separate from you. This is a normal stress response. Don't punish or shame them.
Sleep disturbances. Nightmares, frequent waking, resistance to bedtime — all common after surgery. Create a calm evening routine and stay nearby at night.
Irritability and crying. Your child may not know why they're crying — it's the nervous system releasing stress. Be patient.
A note for parents: you are also carrying an emotional load. Don't forget to care for yourself. Seeking psychological support is not weakness — it's the sensible thing to do.
Nursery and school: when can they return?
Depending on the type of surgery, your child can return to nursery or school after 4-8 weeks. Your doctor will give you the specific timeline.
Before returning, meet with the class teacher and PE teacher. Explain: physical activity is still limited, your child may tire more easily and needs the option to rest, falls and rough contact should be avoided, and if there's a medication schedule, agree on who to contact at school.
Talk to your child too. Instead of "you're sick," try: "your heart is very strong now — we just need to be careful for a little while."
Sports and physical activity: the most asked question
"Will my child be able to play sports?" — almost every parent asks this. The answer is individual: it depends on the type of defect, whether the repair was complete, and the current function of the heart.
First 6 weeks — no active physical activity. Light walks — yes. Running, jumping, climbing — no.
1-3 months — light, non-competitive play. Cycling and swimming — not yet.
3-6 months — after a medical review, activity can gradually increase. Your child will signal when it's too much — fatigue or breathlessness means rest.
6-12 months — most children are doing the same activities as their peers.
After 1 year — with a fully corrected defect, such as complete closure of a ventricular septal defect, children can typically participate in sports without restriction. Some go on to compete professionally.
Removing physical activity entirely is the wrong approach. Movement strengthens the heart. Build an individual plan together with your doctor.
When to seek urgent medical attention
If you notice any of the following — don't wait:
— Lips, fingernails, or tongue turn blue;
— Breathing is rapid or laboured;
— Fever above 38°C lasting more than 24 hours;
— The wound becomes red, swollen, or shows discharge;
— Your child is unusually pale and lethargic;
— An infant suddenly refuses to feed;
— Heartbeat feels very fast or irregular.

Follow-up appointments: long-term monitoring
The surgery is done — but your connection with the cardiologist and cardiac surgeon continues. Most children need regular check-ups for several years.
These start more frequently (every 3-6 months) and gradually become less frequent (once a year). ECG, echocardiography, and other investigations are performed as needed.
Don't skip these appointments — even when your child feels perfectly well. Early monitoring allows any issues to be caught in time.
A final word — for parents
You made it through. From diagnosis to surgery, every step carried anxiety, sleepless nights, and tears. It wasn't easy.
But the statistics are on your side. In modern pediatric cardiac surgery, success rates are 95-99%. The vast majority of children who undergo heart surgery go on to live full, active, happy lives. They grow up. They study. They play sport. They love.
That small heart is strong. You knew it. That's why you said yes to surgery.
