RESUMEN
Valve surgery involves valvular substitutes that expose to different types of complications that can lead to re subsequent interventions. was to identify the predictors factors of in-hospital morbidity and mortality of re interventions after valve replacement. Retrospective study of 73 consecutive patients who underwent a re valve replacement between 1985 and 2010 in the Cardiovascular Surgical department of La Rabta hospital. The average age at further surgery was 44 years [15-80 years] and sex ratio of 0.87. The average time between interventions was 10 years [3 days -33 years]. Different etiologies were found prosthesis thrombosis [36.9%]. The overall hospital mortality was 36.9%, 11 intraoperative deaths and 16 immediate postoperative deaths. The iterative intervention of valve replacement surgery is increasingly mastered by the surgical team. According to this study, the prognosis depends mainly on the patient preoperatively state, the cause of further surgery and its mode of occurrence
