Bacterial endocarditis is the name given to an infection affecting the valves and lining of the heart. The infection is rare in a normal heart, and is due to bacteria present in the blood stream settling on some abnormal area of the heart, usually a diseased valve or septal defect. It is most common on the mitral and aortic valves, rare on the pulmonary valve, and very uncommon on the tricuspid valve. Patent ductus and ventricular septal defects may become infected, but atrial septal defect only very rarely. Infection is not uncommon at the site of coarctation of the aorta.
