Results of a second-opinion program for coronary artery bypass graft surgery

Second opinions for surgical procedures are now being sought by patients or are required by insurance carriers. We examined outcomes among 88 patients (76 men; average age, 59 years) referred for a second opinion as to the need for coronary artery bypass graft surgery. All patients had undergone coronary arteriography, which disclosed in 63 (72%) multivessel coronary artery disease, while in the remaining 25 patients single-vessel disease involved the left anterior descending coronary artery. Continuation of medical therapy was recommended for 74 (84%) of the 88 patients. Sixty of these 74 patients chose this option and continued to receive medical therapy without any fatalities during a follow-up period of 27.8 months. The remaining 14 patients elected to cross over to surgical therapy at an average of 11.3 months from the second opinion. We conclude that second opinions for selected, motivated patients slated for coronary artery bypass graft operation afford a significant and safe option. Moreover, a majority of patients will adhere to a second opinion recommending medical therapy, thus reducing the need for surgical intervention by as much as 50%. Since the study was based on a small sample size of self-selected patients, these data require caution in extrapolating to the general population with coronary artery disease.
