STS Risk Score Calculator

The Society of Thoracic Surgeons’ risk model calculates the risk of operative mortality and morbidity of adult cardiac surgery on the basis of patient demographic and clinical variables. We have developed our own similar Cardiac Surgery Risk Assessment Calculator.

Use our Online  Cardiac Surgery Risk Assessment Calculator

Our calculator was designed to estimate the risk of morbidity and mortality following the most common types of cardiac surgery, including coronary bypass and other procedures. It is only a tool to:

• Guide discussions about the potential outcomes of open heart surgery,
• Compare the results with actual outcomes,
• Measure estimates and outcomes against objective standards of performance.
