Endocarditis is a condition when an infectious organism, typically bacteria
, infects the inside of the heart. It usually involves the heart valves. This can cause the heart valves to malfunction and become leaky, but it can also result in the ejection of blood clots and bacteria out to the body where they can cause strokes, kidney failure
, and other complications. Sometimes endocarditis can be cured with a very long course of intravenous antibiotics, but often times the valve
must be surgically repaired or replaced. People with endocarditis are at increased risk of a second episode later in life because the damaged areas of the heart are more susceptible to infections. If somebody with endocarditis continues to use intravenous drugs, that is very dangerous and can result in more surgery or even death.
