Answer

Answer

Frequently used preoperative risk models for noncardiac surgery, including the American College of Surgeons (ACS) National Surgical Quality Improvement Program (NSQIP) Risk Calculator and the Revised Cardiac Risk Index (RCRI), do not include AS in their calculations of risk assessment. However, several studies suggest that severe AS is associated with increased morbidity and mortality after noncardiac surgery. [5, 6, 7]
