I09.1: Rheumatic diseases of endocardium, valve unspecified
Your immune system is attacking your body after an illness involving certain bacteria. The inner membrane of your heart has become inflamed as a result.
In the past you had an infection caused by certain bacteria. You had a sore throat or tonsillitis caused by bacteria. Your immune system fought the bacteria using certain antibodies. However, these antibodies can also attack the body’s tissue. The antibodies have been damaging your heart for a long time.
The heart is composed of a thick muscle layer and a thin membrane in the heart interior. An external sac, the pericardium, surrounds the heart. This sac consists of a tight membrane. When the inner membrane of the heart becomes inflamed, it is usually the heart’s valves that are affected. There are 4 valves in the heart. These valves ensure that the blood flows in the right direction. So they have to close tightly. They also have to open up fully so that the blood can be properly pumped out of the heart.
When a cardiac valve is inflamed, it may no longer work properly. The valve may then no longer close properly. As a result, the heart is no longer able to pump the blood through the body so well.
