Answer

Approximately 15-25% of cases of IE are a consequence of invasive procedures that produce a significant bacteremia. Because only 50% of those who developed valvular infection following a procedure were identified as being candidates for antibiotic prophylaxis, only approximately 10% of cases of IE can be prevented by the administration of preprocedure antibiotics. Maintaining good oral hygiene is probably more effective in the overall prevention of valvular infection because gingivitis is the most common source of spontaneous bacteremias.
