Summary of the 2007 AHA Guidelines for IE Prophylaxis
Cardiac conditions associated with the highest risk of adverse outcome from endocarditis for which prophylaxis with dental procedures is recommended
1. Prosthetic cardiac valve
2. Previous IE
3. Congenital heart disease (CHD)*
a. Unrepaired cyanotic CHD, including palliative shunts and conduits
b. 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+
c. Repaired CHD with residual defects at the site or adjacent to the site of a prosthetic patch or prosthetic device (which inhibit endothelialization)
4. Cardiac transplantation recipients who develop cardiac valvulopathy
*Except for the conditions listed above, antibiotic prophylaxis is no longer recommended for any other form of CHD.
+Prophylaxis is recommended because endothelialization of prosthetic material occurs within 6 months after the procedure.
