Objective: to describe the epidemiological characteristics and the results of early surgical treatment of patients diagnosed with infectious endocarditis who underwent surgery in the Department of Cardiovascular Surgery in the Medellin Clinic, Colombia. Methods: observational, descriptive, retrospective study of all the patients diagnosed with infective endocarditis treated by surgery in the Medellin Clinic between January 2003 and January 2010. Results: a total of 54 patients were included. 37 (68.5%) were male. Mean age was 57.5 years (9-76 years). 77.7% had a risk factor for developing infective endocarditis; among the most prominent risk factors were chronic renal failure (CRF), patients on hemodialysis (18.5%) and heart valve prostheses (18.5%). 66.7% of the blood cultures were positive. Staphylococcus aureus was the main germ isolated in 40.7% of patients. 81.4% of the involved valves were native, with mitral valve predominance (44.5%) and 7.5% had involvement of two valves. In 68.5% the reason for the consultation was heart failure and 35.3% had embolic phenomena as the initial manifestation or associated (16.7% cerebral, pulmonary 13%, spleen 5.6%). In 83.3 % of cases early surgery was performed: 66% received mechanical valves. The three-month total mortality was 13% (3.7% intraoperative death, mortality at 30 days 9%). The median length of hospital stay was 36 days (7-130 days). In this study the total mortality reported is at the lower limit of the reported in the world. One of the reasons attributed to this finding is the early surgical management that is the protocol in the service.
