A child with TETRALOGY OF FALLOT (TOF) that was REPAIRED in childhood — do they need antibiotic prophylaxis for dental procedures?
Show answer and explanation
Correct answer: C. Refer to cardiologist BEFORE deciding on prophylaxis (since guidelines are complex)
✓ C) Refer to cardiologist before prophylaxis decision is correct.
AHA 2007 guidelines: Prophylaxis indicated for: (1) Prosthetic cardiac valve; (2) Previous infective endocarditis; (3) Congenital heart disease (CHD) only in specific cases: unrepaired cyanotic CHD, repaired CHD with RESIDUAL defects near patch/prosthetic material, completely repaired CHD in first 6 months post-repair. TOF repaired: if repair complete with no residual defects beyond 6 months → NO prophylaxis needed. If uncertain about residual defects → refer to cardiologist. The cardiologist consultation is appropriate when the dental provider is unsure about the specifics of the cardiac repair.
