The road to tetralogy of Fallot surgery in Germany usually starts with a diagnosis in the first weeks of life or even before birth, and parents first hear four difficult words and the word «operation». Then come the questions their local hospital answers differently every time: when to operate, in one stage or two, and what happens twenty years from now.
This page explains tetralogy of Fallot treatment in Germany: what hospitals check before the procedure, how the complete repair and later interventions work, who looks after the child and how the trip is organised. For other defects, see paediatric cardiology in Germany.
What tetralogy of Fallot is
Tetralogy of Fallot combines four changes in the heart: a hole in the wall between the ventricles, a narrowing of the outlet from the right ventricle to the pulmonary artery, an aorta sitting over the hole, and a thickened right ventricular wall. As a result, part of the blood crosses the hole into the aorta and travels round the body without passing through the lungs, so the child is short of oxygen.
In a child this shows as blue lips and nails and tiring quickly during feeding and crying; some children have episodes in which the blueness suddenly worsens. Severity depends above all on how tight the narrowing is, which is why some children reach a surgeon urgently and others on a planned list.
Unlike general texts on heart defects, this page deals with one specific defect. In some children it comes together with a genetic condition, which is why a geneticist is part of the work-up. For heart operations in general, see heart surgery in Germany.
What is assessed before surgery
The basis is an echocardiogram with Doppler, performed by a paediatric cardiologist. This is what shows the size of the hole, the degree of narrowing and the state of the pulmonary valve; Doppler adds how fast and in which direction the blood flows.
When the anatomy is unclear, cardiac MRI or CT is added to assess the pulmonary arteries and collaterals, extra vessels carrying blood to the lungs straight from the aorta; in selected cases, cardiac catheterisation follows. The purpose is not to «look at everything» but to establish whether the pulmonary arteries are wide enough for a complete repair. The approach is set out in the German paediatric cardiology society’s guideline on tetralogy of Fallot (DGPK, in German).
Families bring imaging discs, echo reports, discharge summaries and laboratory results, yet the echocardiogram is almost always repeated in Germany because the decision is made on the team’s own images. This is routine.
How the repair is done and what follows
In the complete repair, the surgeon closes the hole in the septum with a patch and widens the path from the right ventricle to the pulmonary artery. It is open-heart surgery on cardiopulmonary bypass, with a heart-lung machine doing the work of the heart and lungs. The hospital sets the timing according to the child’s condition and anatomy.
Sometimes an interim, palliative stage comes first. If the pulmonary arteries are too narrow or the child is too small and unstable, a shunt (an artificial connection between vessels) is placed or the outlet is widened with a stent, a small mesh tube, to let the lungs and pulmonary arteries grow; the complete repair follows later. This is a planned sequence, not a failure.
Afterwards doctors monitor the pulmonary valve, which tends to leak with time, the size of the right ventricle and the heart rhythm. Some patients need the valve replaced years later, now sometimes through a blood vessel rather than by open surgery. Follow-up does not end with childhood: adults with a repaired tetralogy of Fallot stay under cardiology review for life.
Who operates, and where
This is not the work of a «heart surgeon» in general but of a paediatric cardiac surgeon with a paediatric cardiologist, an anaesthetist and a paediatric intensive care unit, and the decision is taken at a joint review. At the German Heart Centre in Munich, this team includes Prof. Jürgen Hörer, director of the Department of Congenital Heart Defect Surgery and Paediatric Cardiac Surgery, and Prof. Peter Ewert, director of the Department of Congenital Heart Defects and Paediatric Cardiology. In Bad Oeynhausen, Prof. Stephan Schubert is director of the Department of Paediatric Cardiology and Congenital Heart Defects at the Heart and Diabetes Centre NRW.
A hospital is chosen by its experience with congenital defects in children of that age and by whether it has a paediatric cardiac intensive care unit. See also heart centres in Germany and the German Heart Centre in Munich.
Frequently asked questions
How many operations does tetralogy of Fallot need?
The hospital decides after the assessment: a complete repair straight away, or two stages when the pulmonary arteries are too narrow or the child is too small and unstable. In that case a palliative procedure first improves blood flow to the lungs. Years later some patients also need the pulmonary valve replaced.
Does treatment end after tetralogy of Fallot surgery?
No: the child is followed up for life. A paediatric cardiologist monitors the pulmonary valve, the right ventricle and the heart rhythm, and in adulthood a cardiologist for adults with congenital heart defects takes over. If the valve leaks badly, its replacement is planned from these check-ups.
Why is the echocardiogram repeated in Germany?
Because the decision on surgery is made on the team’s own images: the surgeons and cardiologists need to see the hole, the narrowing and the pulmonary valve themselves. This is routine. Discs and reports from home still matter: from them the hospital knows which defect to expect and plans the assessment.
How AlenMed arranges the treatment
AlenMed sends echo reports, discs and discharge summaries to a hospital that operates on congenital heart defects in children. The company works with 86 partner hospitals in 38 German cities and 345 doctors, and its office is in Munich. A parent travels with the child. The paperwork: a translated discharge summary, the hospital’s written reply, the invitation letter and the medical visa; an interpreter joins the conversation with the surgeon.
Ask in advance whether one stage or two is planned, how many days in intensive care are expected, who will follow the child after returning home and how often an echocardiogram is needed, and which documents and images the family takes home.
