A Patient Guide To Adult Congenital Heart Disease

Adult congenital heart disease is a field that exists because paediatric cardiac surgery succeeded. Children born with heart defects now survive to adulthood in large numbers, and there are more adults than children living with congenital heart disease. Repaired hearts are not normal hearts: they need lifelong follow up for rhythm problems, heart failure, valve deterioration and the particular risks of pregnancy. The most common avoidable problem is loss to follow up during the move from paediatric to adult services, which is why structured transition care matters so much.
