Patients who need coronary artery bypass graft (CABG) surgery and have concomitant mild to moderate aortic stenosis present a dilemma to the surgeon and referring physician. We used Markov decision analysis to evaluate the factors that should be considered when deciding whether to electively replace an asymptomatic aortic valve at the time of CABG surgery or to perform CABG alone. Patient age and the degree of aortic stenosis were dominant variables affecting the outcome, if known, the rate of progression of aortic stenosis was also important.
