American Heart Association’s Newest Guidelines On Antibiotic Prophlaxis

The conservative use of antibiotics is indicated to minimize the risk of developing resistance to current antibiotic regimens. Given the increasing number of organisms that have developed resistance to current antibiotic regimens, as well as the potential for an adverse anaphylactic reaction to the drug administered, it is best to be judicious in the use of antibiotics for the prevention of and other distant-site infections.

As opposed to older American Heart Association guidelines that included many (and at times unncessary) prophylactic antiobiotics for dental procedures that involve manipulation of gingival tissue or the periapical region of teeth or perforation of the oral mucosa, the newer guidelines included less illnesses and diseases that need to be covered, including: Prosthetic cardiac valve or prosthetic material used for cardiac valve repair Previous infective endocarditis Congenital heart disease (CHD), Unrepaired cyanotic CHD, including palliative shunts and conduits Completely repaired congenital heart defect with prosthetic material or device, whether placed by surgery or by catheter intervention, during the first six months after the procedure, Repaired CHD with residual defects at the site or adjacent to the site of a prosthetic patch or prosthetic device (which inhibit endothelialization), Cardiac transplantation recipients who develop cardiac valvulopathy.
