DE LA PENA RIVERON, Eric et al. Mortality predictors in the valvar aortic replacement. MEDISAN [online]. 2012, vol.16, n.10, pp. 1504-1512. ISSN 1029-3019.

An observational and analytic case-control study was carried out in the Cardiovascular Surgery Department of "Saturnino Lora Torres" Provincial Teaching Clinical-Surgical Hospital in Santiago de Cuba, from 2001 to 2010, in the 248 patients to whom an aortic valvar replacement was carried out, with the use of both mechanical and biological prosthesis, of which the 30 deaths during this stage (cases group) and 60 surgically treated selected at random (controls group) were taken as samples. A prevalence of aortic stenosis, the male sex and the advanced ages could be observed. In the series mortality was 12.1% and as predictors of it, by means of the logistical regression analysis, there were: the levels of high creatinine in the preoperative period, the long time of cardiopulmonary bypass, non optimal myocardial protection, non spontaneous heart recovery and the neurological complications.
