Line 1: Line 1:
 +(1) Endocarditis is a serious [[infection]] of one of the four heart valves.
 + 
 +Endocarditis is caused by a growth of [[bacteria]] on one of the heart valves, leading to an infected mass called a "​vegetation"​. The infection may be introduced during brief periods of having bacteria in the [[bloodstream]],​ such as after dental work, colonoscopy,​ and other similar procedures.
 +
 +(2) The heart is constituted of three types of [[tissues]],​ which are from out- to inside the [[heart]]: the pericardium,​ the myocardium and the endocardium. ​
 +
 +The endocardium is therefore the tissue situated on the internal face of the heart, directly in the contact with [[blood]]. An endocarditis corresponds to an [[inflammation]] (or irritation) of the endocardium or a microbial infection of the [[endothelial]] surface of the heart. ​
 +
 +The most harmed area of the endocardium during an endocarditis is as a rule the one of the cardiac valves, especially if they were injured initially. These valves are to the number of 4: 2 on the right side of the heart and 2 on the left side. 
 +
 +On the right, the tricuspid valve between the auricle and the [[right ventricle]],​ and the pulmonary valve between the right ventricle and the pulmonary artery. ​
 +
 +On the left side of the heart, the mitral valve between the auricle and the [[left ventricle]] followed by the aortic valve between the left ventricle and the [[aorta]].
 +
 +The mitral and aortic valves infective endocarditis is the most frequent. ​
 +
 +The inflammation of the endocardium is often provoked by a generalized infection, the germ being localized initially in another place of the body (teeth, digestive tract...). ​
 +
 +The infective endocarditis is a serious illness in itself, but also because of the context on which it occurs. ​
