[Infective endocarditis. 5-years experience in a third-level reference center in Yucatan, Mexico].

Background: Infective endocarditis is a disease with high morbidity and mortality. The clinical characteristics differ among populations. Therefore it is important to know the characteristics of the disease in our region.

Methods: This is an observational study that included all patients diagnosed with infective endocarditis from 1 January 2009 until 31 December 2014. The data are showed as frequencies and percentages altogether with medians with interquartile range.

Results: 10 cases were included. The median age was 34 years (IQR 26-41). Several risk factors were identified and included: previous valvular heart disease, patients with chronic kidney disease who have had a vascular access and previous history of immunological disease. The native mitral valve was the most affected. The size of vegetations had a median length of 14 mm (IQR 9.3-16). Streptococcus alpha hemolytic was the most common organism. In-hospital mortality rate was 10 %.

Conclusions: The behavior of the disease is similar to other national series. We identify risk factors that could be related to the type of morbidities in the region.
