The American Hospital Association (AHA) and American College of Cardiology (ACC) have now concluded an antiobotic tp prevent after many years is many cases is unnecessary.
Since 1955, the AHA has made recommendations for prevention of infective endocarditis with antimicrobial prophylaxis before specific dental, gastrointestinal (GI), and genitourinary (GU) procedures in patients at risk for its development. However, many authorities and societies, as well as the conclusions of published studies, have questioned the efficacy of antimicrobial prophylaxis in most situations.
The major changes in the updated recommendations included the following:
• The committee concluded that only an extremely small number of cases of infective endocarditis may be prevented by antibiotic prophylaxis for dental procedures even if such prophylactic therapy were 100 percent effective.
• Infective endocarditis prophylaxis for dental procedures is reasonable only for patients with underlying cardiac conditions associated with the highest risk of adverse outcome from infective endocarditis.
• For patients with these underlying cardiac conditions, prophylaxis is reasonable for all dental procedures that involve manipulation of either gingival tissue or the periapical region of teeth or perforation of oral mucosa.
• Prophylaxis is not recommended solely on the basis of an increased lifetime risk of acquisition of infective endocarditis.
I had some dental work done about 6 months ago, and I have mitral valve regurgitation. Dentist was aware of the updated guidelines by AHA.
