It is known that the results of mandatory registries, which include all operated patients, can have high deviation. At the same time, one of the biggest criticisms of this voluntary registry may be related to estimated values unreachable for other populations. STS’ greatest advantage over ESII is probably the sample size, which is updated periodically. Both are recommended for patients undergoing most cardiovascular procedures. Among these models, STS and ESII reverberate the most and, at the same time, are supported by international guidelines. In this scenario, several models have been built and validated, aiming to reach more accurate predictions for specific populations. In addition, it is necessary to fully inform each patient about the risks associated with this procedure, which should be adjusted to the results of the hospital.
In a continuous search for excellence, the application of ever more accurate score models is essential, especially in the evaluation of indications for new cost-effective procedures. One of the reasons for the improvement is associated with the risk stratification brought by risk scores and perioperative optimization. Over time, cardiovascular surgery results have progressively improved.
