The current guidelines for prevention of infective endocarditis from the American Heart Association (2008)do not recommend oral immunoprophylaxis before dental treatment for a patient with a history of rheumatic heart disease.Specific indications for oral immunoprophylaxis may be found on the American Heart Association Website.A history of rheumatic heart disease is no longer considered an indication for oral immunoprophylaxis.If the patient does have one of the currently recommended indications amoxicillin is the standard treatment of choice if no complicating factors are present,such as allergy to penicillins.Tetracycline is never indicated for infective endocarditis prophylaxis just before dental procedures because it is likely to produce bacteremia.Clindamycin is a recommended alternative to amoxicillin if penicillin allergies exist,and erythromycin analogues azithromycin and clarithromycin are also good alternatives.
