I33: Acute and subacute endocarditis
I33.0: Acute and subacute infective endocarditis
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. The thin, inner membrane of your heart is inflamed. This usually affects the heart’s valves. The heart’s valves may then become leaky.
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.
Inflammation of the heart can cause one to feel unwell, and have a high temperature or chest pain, for example.
The inflammation was caused by certain pathogens.
The inflammation may also have affected other layers of your heart.
