A patient with a successfully and completely repaired tetralogy of Fallot (no residual defects, beyond the initial post-surgical risk window) generally requires which approach regarding antibiotic prophylaxis for routine dental procedures?

Antibiotic prophylaxis is NOT routinely needed, per current AHA infective endocarditis prevention guidelines, once repair is complete and more than 6 months have passed without residual defects or prosthetic material complications
Lifelong antibiotic prophylaxis before every dental visit is mandatory regardless of repair status
Prophylaxis is needed only for cleanings, never for extractions
Prophylaxis requirements are unrelated to repair status

Show answer and explanation

Correct answer: A. Antibiotic prophylaxis is NOT routinely needed, per current AHA infective endocarditis prevention guidelines, once repair is complete and more than 6 months have passed without residual defects or prosthetic material complications

Current AHA guidelines reserve infective endocarditis antibiotic prophylaxis for the highest-risk cardiac conditions, including unrepaired cyanotic congenital heart disease and the FIRST 6 MONTHS after a congenital heart defect repair using prosthetic material. After that window, a completely repaired defect (like tetralogy of Fallot) without residual defects generally does NOT require routine dental antibiotic prophylaxis.
