Infectious endocarditis (IE) is defined as the infection of the endocardium or prosthetic material in the heart, whose pathogenesis is bacterial adherence to the vulnerable endocardium or implanted prosthetic material during a bacteremia. Its clinical presentation is highly variable, depending on the micro-organism that causes it, underlying heart conditions and preexisting comorbidities. The annual estimated incidence of IE is up to 10/100,000 in western countries, and mortality of up to 30% in 30 days.
