Sorry to hear of your son's problem. He seems to have developed a cardiomyopathy, more specifically dilated cardiomyopathy meaning the muscle walls of the let ventricle have dilated or stretched and can no longer pump effectively as before. The more it dilates the less effective it is at pumping blood and the lower the EF%. The good news is that if they can resolve the underlying cause his left ventricle can remodel itself back to normal so it is very important to work with his doctors to find the cause. There are many causes, from the Mayo Clinic;
"Some known causes of dilated cardiomyopathy are:
Genetics. A number of genes are linked to dilated cardiomyopathy.
Birth defects. Certain heart defects that are present at birth (congenital) may cause dilated cardiomyopathy.
Infections. Many different types of infections, including those caused by bacteria, viruses, fungi and parasites, can cause dilated cardiomyopathy.
Drug and alcohol abuse. Dilated cardiomyopathy can be caused by long-term use of alcohol or illegal drugs, such as cocaine.
Certain cancer medications. Some drugs that are used in chemotherapy may cause dilated cardiomyopathy.
Exposure to toxins. This condition can also be caused by exposure to some metals and toxic compounds, such as lead, mercury and cobalt."
