[Correspondence] Infective endocarditis and antibiotic prophylaxis
Mark Dayer and colleagues1 outline an increased incidence of infective endocarditis since cessation of antibiotic prophylaxis for dental procedures in the UK. However, as the authors clearly point out, they are unable to show a causal association. The increase might be ascribed to several factors, such as improved coding of infective endocarditis, which was incomplete before 2008. Since 2009, infective endocarditis has almost become a notifiable disease, with reporting of cases to the National Institute for Cardiovascular Outcomes Research (NICOR) by all UK congenital cardiac centres.
