The most common is in the mitral valve site that is affected by the infection.Microorganisms, such as bacteria<br />or fungi. They entered through the blood and colonize on heart valves. This colonization<br />makes the site extremely resistant to antibiotic treatment. The presence of the thrombus on the valve, though, increases the likelihood of infection developing.<br /><br /><br />Thera are 2 type of infectious cardiac diseases :<br />1.<span style="color: rgb(153, 153, 0);"> </span><a style="color: rgb(153, 153, 0);" href="http://emedicine.medscape.com/article/216650-overview">Infective endocarditis</a><br />2. <a href="http://en.wikipedia.org/wiki/Endocarditis"><span style="color: rgb(153, 153, 0);">Pericarditis.</span></a><br /><br /><br /></span><span style="font-size:130%;"><span style="font-weight: bold;">A. . Infective endocarditis</span><br /><br />An infection of the endocardium, heart valves or any cardiac prosthosis is called infective endocarditis.<br />Bacteria is the common causing of infective endocarditis.<br />Once the microorganism begin to proliferate on the valve, it will form what we called vegetation or purulent stuff attached to the heart valve. The bacteria than can attached or attack the heart are streptococci, staphylococci also fungi. Others causes of infective cendocarditis are prosthetic valve, long term indwelling catheters,recent cardiac surgery, <a style="color: rgb(153, 153, 0);" href="http://www.healthsystem.virginia.edu/uvahealth/adult_cardiac/rheumat.cfm">rheumatic heart diseases</a>, congenital heart defect, valvular dysfunction, IV druigs abuse.<br /><br /><br /><br /><span style="font-size:85%;"><span style="font-style: italic; font-weight: bold;font-size:130%;" >Signs and symtomps</span><span style="font-weight: bold;font-size:130%;" > :</span><span style="font-size:130%;"><br /><br />Fever, splenomegaly, petechia, hematuria, cardiac murmur,pleuritic pain, fatigue and weakness.
