Endocarditis (infection of the inner heart lining) causes symptoms of tiredness, sweating, diminished appetite and weight loss. This usually occurs over a period of a few weeks but sometimes if the infection is severe symptoms may occur within days. If this problem is suspected it is important to seek urgent medical advice.
Children and adults with congenital heart disease are at an increased risk of having an endocarditis (infection of the inner heart lining). Whilst this is rare the chances of it occurring can be reduced by taking precautions.
Blood tests are undertaken to try and identify the germ causing the infection and a heart scan test to see the effect it has had on the heart function.The treatment depends upon the findings of the investigations and the severity of the infection but usually antibiotics are for a period of 4-6 weeks with the initial treatment given intravenously.Fortunately with current antibiotics endocarditis is usually curable.
Infections in the heart can occur for no apparent reason but are more common if the teeth are rotten - germs spread into the blood stream and infect the heart. Good dental hygiene is therefore important as are regular visits to the dentist.

Good dental hygiene is therefore important as are regular visits to the dentist.If dental treatment is required then some procedures can cause germs to spill into the blood and infect the heart.It is therefore important that the dentist is informed about the heart condition before treatment. The usual method of avoiding this problem is to give a single dose of antibiotics one hour prior to the treatment to kill any germs beforehand.
Exercise is important even in those with heart disease. It improves the heart function and general sense of well being. It is associated with increased life expectancy and a reduced risk of heart disease in later life. In addition physical activity helps with controlling weight and reducing blood pressure.There are different types of exercise. In static exercise the muscles contract but there is little joint movement eg weight lifting. In dynamic exercise the muscles contract and also move the joints eg running. Each places a different stress on the body and cardiovascular system. In general most types of sports are a mix of the two.Children usually take part in more rigorous exercise at school as they grow older. In Singapore physical education (PE) tends to teach games skills rather than competitive sports. However pupils may take sport for their co-curricular activities (CCA) when training is more intense and competitive. Training for the NAPFA test is also intensive and some pupils with heart problems may have difficulty with the 2.4k run as they often perform less well at endurance type activities.As always parents or patients must seek the advice of their own doctor when deciding how much exercise and to what level is safe - particularly as there are no published guidelines for activity levels in children
The Bottom Line
Most children with heart disease can have all the normal vaccinations at the appropriate time.However some children with an immune deficiency (DiGeorge syndrome or an isomerism) and those who are receiving immunosuppression - for example following transplantation require a different vaccination schedule.
Before travelling anywhere unusual or a long distance make sure that you:
Those with cyanotic heart disease ("blue" due to reduced oxygen in the blood) can still travel but aircraft at altitude have less oxygen in the air than at ground level and so the blueness may be more apparent. This does not usually cause symptoms but if necessary airlines can arrange for additional oxygen to be available on the aircraft.For long aircraft flights it is sensible to use the support stockings and take aspirin or an equivalent unless your doctor advises against it.
Special diets are not normally necessary for those with heart disease. As with everyone it is important to have a balanced diet and not to eat to excess. It is however important to maintain a normal weight - excess weight means more work for the heart.
Most children with heart disease are no more prone to infections than any other children. Some however are likely to get chest infections - particularly those with holes in the heart (ASD, VSD, PDA).In addition some heart diseases are also associated with an immune deficiency and infections therefore are more common. The majority of childhood infections are viruses and get better without antibiotics. In any case of doubt professional medical help should be sort and the doctor will decide if antibiotics are necessary.
Most children with heart disease do not require medication. Some however need them to:
The majority of these medicine have been used for many years and are very safe but like all drugs side effects may occur - especially if there is another illness or a change in other medication. If unusual symptoms or side-effects occur whilst on medication it is important to inform the doctor immediately.
Most women with heart disease are able to undergo a normal pregnancy and delivery.The exceptions are those with severe cyanosis when there is usually insufficient oxygen in the blood supply to the placenta to sustain the baby. Most of these pregnancies spontaneously abort.Women with pulmonary hypertension (high lung artery pressure) are not usually advised to get pregnant as there is a serious danger to their life.As with any medical problem it is essential that medical advise is taken - preferably before the event so that the pregnancy can be monitored and if treatment is necessary it can be undertaken early.If a women herself has a heart problem then there is an increased risk that her child will have a problem too. The risk is around 6%. If a man has a heart problem then the risk is 2%. If the couple have had a previously affected child then the risk is about 2%. The risks quoted above are averages - the actual risk varies considerably between the various heart conditions. There is also some evidence that taking vitamins for 3 months prior to and the first 3 months of the pregnancy can reduce the chance of heart disease occurring in the baby.
