Objective: To describe clinical, microbiological and echocardiographic aspects of endocarditis in a specific group of patients without intracardiac devices or underlying structural heart disease. Method: Retrospective study, clinical records and echocardiographic reports were reviewed during the period 1997 to 2020. Duke’s modified criteria were applied. Statistical analysis: univariate expressed in frequencies, using measures of dispersion and central tendency. Results: 30,000 echocardiographic reports were reviewed, only 1350 had infectious endocarditis as a reason for sending, of which 248 cases were selected. The mean age was 48.1 ± 16.7 years. 140 men (56%) and 108 women (44%). The most frequent echocardiographic sign was vegetation, in 278 (93.60%), and most common location was mitral (35.55%), with a higher number of cases in the right ventricle than expected. The most common systemic disease was kidney disease, in 135 (41.08%). A case of Streptococcus thoraltensis not previously reported in Mexico was identified. Conclusions: The presence of infectious endocarditis has increased due to invasive in-hospital and drug procedures. Due to their complexity, multidisciplinary teams are indispensable.
