Children who have undergone open heart surgery with a patch are at increased risk for infection, particularly which condition?

• A. Pneumonia
• B. Subacute bacterial endocarditis
• C. Gastroenteritis
• D. Meningitis

Answer: (B)

The main concept is that implanted heart material, like a patch, provides a surface for bacteria to cling to when bacteria are circulating in the blood, so infection of the heart’s inner lining or the patch itself can occur. Subacute bacterial endocarditis is the classic infection in this situation because organisms from common sources (such as the mouth) can seed the prosthetic material and form creeping vegetations on the patch or valves. Its course is often gradual, with subtle symptoms like low-grade fever, fatigue, and murmur changes, which is why it’s emphasized as a risk after open-heart repair with a patch. Other infections listed affect different body systems (lungs, gastrointestinal tract, meninges) and, while serious, are not as specifically associated with prosthetic heart material. In children with a heart patch, the risk of endocarditis is the key concern, and preventive measures around bacteremia sources, especially dental procedures, are important to minimize this risk.
