1. Introduction

Infective endocarditis (IE) at the right side of the heart is quite rare; it represents the 5–10% of IE cases. It is seen most frequently in people with intravenous drug addiction; nevertheless, other portions of the population are in high risk of developing this disease such as patients with indwelling catheters, cardiac devices, congenital cardiac pathologies, and immunocompromised diseases [1–3].

The evolution of right-heart IE is much better than the left-side IE with a lower rate of mortality (3–30%) [3]. This pathology is more frequent in people between 20 and 61 years, with a mean age of 38 ˜ 15 years [4].

Staphylococcus aureus is the predominant organism (60–90% of cases) with the methicillin-resistant strains becoming more prevalent lately [3, 5]. The tricuspid valve is by far the most effective structure (90%) in right-side infective endocarditis (RSIE) [5].
