Who is at risk for endocarditis?
People with existing diseases of the heart valves (aortic stenosis, mitral stenosis, mitral regurgitation, etc.) and people who have undergone heart valve replacements are at an increased risk of developing endocarditis. These people are usually given antibiotics prior to any procedure which may introduce bacteria into the bloodstream. This includes routine dental work, minor surgery, and procedures that may traumatize body tissues such as colonoscopy and gynecologic or urologic examinations. Examples of antibiotics used include oral amoxicillin (Amoxil) and erythromycin (Emycin, Eryc,PCE), as well as intramuscular or intravenous ampicillin, gentamicin, and vancomycin.
How is endocarditis diagnosed?
The infection on the valve can cause build up of nodules on the valves called "vegetations". These valve vegetations can be detected by echocardiography (an ultrasound examination of the heart). The most accurate method of detecting valve vegetations is with a procedure called transesophageal echocardiography (TEE). In this procedure an echo-transducer is placed on the tip of a flexible endoscope. The endoscope is inserted through the mouth into the esophagus. The transducer at the tip of the endoscope is then able to take sound wave "pictures" of the heart valves located adjacent to the lower esophagus. It is important to realize that endocarditis may exist without visible vegetations on the heart valve; the exact diagnosis is made by the identification of bacteria in a blood culture, in the appropriate clinical setting.
