What are the highest risk groups for which prophylactic antibiotics may be considered?
The American Heart Association (AHA) recommends that prophylactic antibiotic drugs before certain dental procedures may be considered for those in the highest-risk groups, which include cardiac valve repair with a prosthetic valve or prosthetic material; previous IE; certain CHD (unrepaired cyanotic CHD, repaired CHD with prosthetic material or device during the first 6 months after the procedure, repaired CHD with residual defects at the site or adjacent to the site of a prosthetic patch or prosthetic device); and recipients of cardiac transplants who develop IE.
