Antibiotic Prophylaxis for Mitral Valve Disease and Dental Procedures

Introduction to Prophylaxis Guidelines

The American College of Cardiology recommends that most patients with native mitral valve disease do not require antibiotic prophylaxis before dental procedures 1, 2, 3, 4, 5

The American College of Cardiology and American Heart Association guidelines state that patients with prosthetic mitral valves must receive antibiotic prophylaxis before dental procedures that manipulate gingival tissue, the periapical region of teeth, or perforate the oral mucosa 6, 7
The American College of Cardiology and American Heart Association guidelines recommend that mitral stenosis, mitral regurgitation, and mitral valve prolapse do not require antibiotic prophylaxis for dental procedures 1, 2, 3

The American College of Cardiology and American Heart Association guidelines indicate that prophylaxis is required for dental procedures involving manipulation of gingival tissue, the periapical region of teeth, or perforation of the oral mucosa in patients with prosthetic mitral valves 6, 7, 8
The American College of Cardiology and American Heart Association guidelines state that prophylaxis is not needed for routine dental X-rays, placement or adjustment of removable prosthodontic or orthodontic appliances, shedding of deciduous teeth, trauma to lips and oral mucosa, local anesthetic injections in non-infected tissues, or treatment of superficial caries in patients with prosthetic mitral valves 8

The American College of Cardiology recommends amoxicillin 2 g orally, given 30-60 minutes before the procedure, as the standard regimen for patients with prosthetic mitral valves without penicillin allergy 7, 8
The American College of Cardiology recommends cephalexin 2 g orally or cefazolin 1 g IM or IV for patients with prosthetic mitral valves and penicillin allergy without history of anaphylaxis/angioedema/urticaria 7
The American College of Cardiology recommends clindamycin 600 mg orally or IV, given 30-60 minutes before the procedure, for patients with prosthetic mitral valves and severe penicillin allergy 7, 8

The American College of Cardiology acknowledges that some clinicians and patients may feel more comfortable continuing prophylaxis for severe mitral valve prolapse, although this is not a guideline recommendation 2, 3, 4, 5

The American College of Cardiology and American Heart Association guidelines state that antibiotic prophylaxis is not recommended for gastrointestinal or genitourinary procedures, even in patients with prosthetic mitral valves 7, 8

The current recommendations are based on expert consensus, recognizing that the catastrophic outcomes of endocarditis in prosthetic valve patients justify prophylaxis despite the lack of definitive evidence 7
