AbstractWe report two cases of aortic valve replacement (AVR) for severe aortic stenosis (AS) before the cancer operations. Severe AS poses a great risk for noncardiac surgery. In the ACC/AHA 2007 Guideline on Perioperative Cardiovascular Evaluation and Care for Noncardiac Surgery, if the AS is symptomatic, elective noncardiac surgery should generally be postponed or canceled. Such patients require AVR before elective noncardiac surgery. On the other hand, in patients with severe AS who refuse cardiac surgery, noncardiac surgery can be performed with a mortality risk of approximately 10%. In our cases, severe AS was found in the preoperative examination. We informed them about necessary AVR before noncardiac surgery, and patients consented to our suggestion. AVR was performed around 7 days after this consent, and cancer operation was performed around 30 days after the AVR. However, there are no clear guidelines for this interval between AVR and cancer operation. In our cases the patients underwent the cardiac surgery and noncardiac surgery in a short period without serious complication in the perioperative management. It is very important to discuss among surgeon, cardiovascular surgeon, cardiologist and anesthesiologist. Especially anesthesiologist should take an important role in organizing these departments for such patients.
