Endocarditis is the growth of blood clots on the valves and inner walls of the heart. They can cause damage to the heart. The growths can also break off and block blood flow in other areas of the body such as the brain or lungs.
Certain health problems let the blood to clot too easily. The clots can form and stick in any blood vessel or in the heart. Areas of damage, like a defective heart valve, are ideal places for clots to stick and grow. The heart valve may be scarred from an illness or a birth defect.

Your chances of endocarditis are higher if you have:
You will be asked about your symptoms and health history. A physical exam will be done. The doctor may test for endocarditis if there have been problems with blood clots.
You may have:
- Blood tests—to check for infection or clot issues
- Echocardiogram—to view heart and heart valves
The goal is to stop the growth of more clots. This will help to prevent complications like a stroke. Medicine can make it harder for blood to clot. This can stop clots, but also increase the risk of bleeding.
Related conditions that increase the risk of blood clots will also need to be treated.
