Clinical facts and numerical data support interpretations of quality of life and survival in patients with valvular heart disease. Such data are useful in decision making regarding the interruption of natural history and replacement by a hemodynamic post-correction history. Interdisciplinary competence and expertise are required to maximize the necessary and possible results. However, the ideal of recommendations to achieve the highest degree of therapeutic satisfaction by patients with valvular heart disease is influenced by a set of variables, related in part to the specifications of the patient, and part to the limitations of methods. The rationale of the risk score validated for multiple markers is the addition of quantitative accuracy to the clinical assessment based on the heterogeneity of individual experience and intuition. In this context, the use of risk scores to predict postoperative mortality are useful tools, easy to apply and that gives us objective data on the patient's situation. None of the available tools (EuroSCORE, STS score and Ambler Score) used in healthcare has been validated has in our population.
