Which patient group is explicitly listed as needing endocarditis prophylaxis despite prior repair?

Which patient group is explicitly listed as needing endocarditis prophylaxis despite prior repair?

• A. Children with repaired congenital heart disease with residual defect at the repair site
• B. All children with congenital heart disease daily
• C. All CHD before dental, GI, and GU procedures
• D. Five years after repair

Answer: (A)

Endocarditis prophylaxis is used for patients with certain congenital heart conditions or repaired repairs where abnormal heart surfaces or prosthetic material can harbor bacteria and become infected if bacteremia occurs during procedures. If the congenital heart defect has been surgically repaired but there is a residual defect at the repair site, the area remains an abnormal surface with abnormal blood flow. That residual defect or the prosthetic patch/device at the repair site creates a ongoing risk for endocarditis whenever bacteremia could occur, so prophylaxis is explicitly recommended for such patients, even after repair. The other scenarios don’t fit this specific risk pattern: not all children with congenital heart disease require routine prophylaxis, and prophylaxis isn’t automatically indicated for every dental, GI, or GU procedure in all CHD patients—only those with residual defects at the repair site or with prosthetic material. Five years after repair without a residual defect does not meet the criteria.
