I51: Complications and ill-defined descriptions of heart disease

I51.2: Rupture of papillary muscle, not elsewhere classified

The heart pumps blood through the body. Inside the heart are 4 chambers. There are 2 heart atria and 2 ventricles. Both heart atria and both ventricles are separated from each other by a partition. 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.

Two valves are moved by particular muscles. The muscles are connected to the inner wall of the heart. In your case, these muscles have ruptured. As a result, the valves may not be closing correctly and they may be leaky.
