Answer

Although many earlier studies did not differentiate between symptomatic and asymptomatic severe AS, emerging data suggest that during intermediate- to high-risk noncardiac surgery, patients with asymptomatic AS may have morbidity and mortality outcomes similar to those of patients without AS. [7, 21, 22] In a study by Agarwal, significant predictors of 30-day mortality and postoperative MI after noncardiac surgery were as follows [7] :

  • High-risk surgery
  • Symptomatic severe AS
  • Coexisting mitral regurgitation
  • Preexisting coronary artery disease (CAD)

Thus, these factors should be taken into account in assessing a patient’s suitability for noncardiac surgery.
