Complications in other parts of the body

Small bits may break off from the vegetations on the infected heart valves. These get carried in the bloodstream, and lodge in other parts of the body. This can cause various symptoms. For example:

• Small spots may appear under the fingernails, in the eyes, or other parts of the body.
• Infections may develop in other parts of the body.
• The spleen may enlarge as it is the main organ that fights off blood infections.
• If a larger chunk of vegetation breaks off then it can block the blood flow in a main artery. For example, if it gets stuck in an artery in the brain it can cause a stroke or sudden loss of vision in one eye.
