Which of these statements is FALSE about infective endocarditis in l.V. drug abusers-
**Core Concept**
Infective endocarditis in IV drug abusers is a type of infective endocarditis that occurs due to the introduction of bacteria into the bloodstream through non-sterile needles or contaminated IV equipment. This condition often affects the tricuspid valve, which is the valve between the right atrium and right ventricle.
**Why the Correct Answer is Right**

This is because the tricuspid valve is exposed to the venous bloodstream, which carries bacteria from the skin and other potential sources of infection. The bacteria most commonly involved in infective endocarditis in IV drug abusers include Staphylococcus aureus and Streptococcus species.
