The new guidelines have also been endorsed by the Infectious Diseases Society of America, the Pediatric Infectious Disease Society, and the American Dental Association. Previously all people with CHD received antibiotics before dental and invasive procedures to prevent endocarditis. The new guidelines, however, require antibiotics prior
