A child needs an extraction four months after prosthetic congenital-heart repair. What determines prophylaxis?
Confirmed prosthetic repair within six months plus extraction meets the patient and procedure criteria for infective-endocarditis prophylaxis.
- Confirm repair details and residual defects; clarify uncertainty with cardiology.
- Review allergy, current antibiotics, weight, and ability to take oral medication.
- Give the selected single dose 30–60 minutes before treatment; this is not a routine postoperative course.
