Correct answer: B — Yes — patients with prosthetic heart valves (biological or mechanical) are in the highest-risk category for IE and should receive antibiotic prophylaxis before dental procedures involving gingival manipulation
Yes. A bioprosthetic aortic valve is a prosthetic heart valve, and prosthetic valves—biological/bioprosthetic or mechanical—place the patient in the high-risk group for infective endocarditis. Dental extraction is an invasive dental procedure involving gingival/oral surgical manipulation, so current UK dental implementation advice recommends offering antibiotic prophylaxis before the procedure. This is not limited to mechanical valves, and the “no prophylaxis for any dental procedure” option is too broad for current high-risk UK practice.
