If catheterization shows clinically significant stenosis, what is recommended prior to proceeding with elective noncardiac surgery?

• A. Revascularization
• B. Proceed to surgery with standard anesthesia care
• C. No treatment required
• D. Only monitor

Answer: (A)

When catheterization shows clinically significant stenosis, the heart has areas of fixed blood flow limitation that may not meet the increased oxygen demand during surgery. The stress of anesthesia, tachycardia, and hemodynamic shifts can trigger myocardial ischemia or infarction in these regions. Revascularization—either bypass surgery or percutaneous intervention—restores adequate coronary perfusion before the additional stress of an elective noncardiac procedure, lowering the risk of perioperative cardiac events. This approach is favored over proceeding with standard anesthesia care or simply monitoring, which do not address the underlying flow limitation and leave the patient at higher risk. After revascularization, the timing of subsequent noncardiac surgery depends on the type of revascularization and healing/antiplatelet considerations, but the priority is to optimize coronary perfusion prior to elective noncardiac surgery.
