Infective endocarditis is a microbial infection of the endothelial surface of the heart and since last 2 decades, the incidence of tricuspid endocarditis is increasing. Right-sided infective endocarditis accounts for 10-15% of all cases. The patients addicted to intravenous (IV) drugs and with long-term IV catheters or with antiarrhythmic devices, such as implantable defibrillators and pacemakers, have increased the risk of right-sided endocarditis. Here, we report a child with isolated tricuspid valve endocarditis without any cardiac malformation.
