I39: Endocarditis and heart valve disorders in diseases classified elsewhere

I39.8: Endocarditis, valve unspecified, in diseases classified elsewhere

The heart is composed of a thick muscle layer and a thin membrane inside the heart. An external sac, the pericardium, surrounds the heart. This sac consists of a protective 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.

This inflammation of the heart (carditis) can make one feel weak or have a high temperature. Your carditis has been caused by another disorder.
