The aim of this Factsheet is to explain what Dilated Cardiomyopathy is, what effect it will have on a child and how it can be treated
Dilated cardiomyopathy is a disease of the heart muscle. Dilated means enla
rged, cardio concerns the heart and a myopathy is a muscular disease. Dilated cardiomyopathy means that the left ventricle becomes stretched and ‘floppy’. DCM weakens the heart muscle so that it works less efficiently and cannot pump enough blood to the lungs and around the body. This can lead to breathlessness and fluid to build up within the body.
It is not always certain what causes DCM and it can develop at any age. Sometimes dilated cardiomyopathy can be inherited; sometimes it can develop from viral infections, certain medicines, or from autoimmune diseases for example.
DCM is often discovered because a child becomes tired easily, breathless, and perhaps has some swelling caused by fluids building up. There may also be a fast or slow heart beat and the doctor may hear an abnormal heart sound (heart murmur) through a stethoscope, or a large heart may be visible on an x- ray.
When a heart problem is suspected several tests may be used:
Treatment cannot cure DCM, but medicines can help your child’s heart to stabilise, and in many cases medicines reduce the risk of the condition getting worse. It is possible that your child may recover spontaneously.
If your child’s condition cannot be controlled using these treatments he or she may be assessed for a heart transplant.
