BAHAMONDES S, JUAN CARLOS et al. Risk factors related to mortality in heart valve replacement for complicated endocarditis. Rev Chil Cir [online]. 2008, vol.60, n.2, pp. 116-121. ISSN 0718-4026.  doi: 10.4067/S0718-40262008000200006.

Infectious endocarditis is a severe illness related to the aggressiveness of the microbial agent to the cardiovascular system. Heart valve replacement surgery is the definitive treatment in these patients but is related to high mortality when the structural damage is severe. Objective: To assess risk factors related to mortality in patients operated for complicated endocarditis. Patients and method: Descriptive study of 32 patients operated between 1993-2005 period in which clinical factors were evaluated and related to mortality. Results: Overall mortality was 25%, mainly in the first two weeks after surgery (60%). Mortality related risk factors were sepsis (p =0.002), mitro-aortic replacement (p <0.001) and alcoholism (p =0.049). Actuarial survival probability is 78% to 146 months in the group. Conclusion: Mortality is similar to others cardiac centres and is higher in the first two weeks alter surgery. Mitro aortic replacement and sepsis are the main factors of early mortality risk
