Magnification 2363x.


Infective Endocarditis1
  • The prevalence of cardiac device infections in patients with S. aureus bacteremia (SAB) is approximately 50%.
  • The prevalence of infective endocarditis in SAB patients ranges from 11 to 50%.
  • The number of cardiac devices implanted has increased dramatically together with the number of device-related infections.
  • The rates of cardiac rhythm management device infections increase faster than the implant rate.
  • Infective endocarditis has become more difficult to treat due to a high number of MRSA infections and the increasing number of device infections.
  • Strong evidence supports the use of screening with echocardiography in patients with SAB.
