What Are The Symptoms Of Bacterial Endocarditis?

The infection of the innermost lining of the heart, mostly heart chambers and heart valves is called endocarditis. It may be caused by bacteria, virus, fungi, congenital heart diseases and other causes. The inflammation of endocardium (innermost lining) of the heart mediated by bacteria is termed as bacterial endocarditis. It is an uncommon disease which has serious potential to damage the heart and can trigger fatal complications threatening the life.

Although our heart is designed in such a manner, that it cannot be affected by infection in normal healthy persons. Those who are immune deficient or, have congenital heart disease or undergone some heart implant surgery, are more prone to develop the infection.
