The most common cause of endocarditis for dental, oral, respiratory tract, or esophageal procedures is S viridans (alpha-hemolytic streptococci). Antibiotic regimens for endocarditis prophylaxis are directed toward S viridans, and the recommended standard prophylactic regimen is a single dose of oral amoxicillin Antibiotic prophylaxis is not routinely indicated for cardiac catheterization.
