Croce Hospital. Of these patients, 126 patients with an indication selected for comorbidities or 1-vessel disease underwent OPCAB performed by 4 low-volume surgeons, and 186 unselected patients underwent OPCAB performed by a single high-volume surgeon.</p><p><b>Results:</b> OPCAB performed by low-volume surgeons was associated with less complete revascularization and less arterial conduit use. Early result analysis showed a low rate of in-hospital or 30-day adverse events. The 5-year survival was 0.88 (0.02 SE). OPCAB performance by a high-volume surgeon and complete revascularization were shown have a protective effect for midterm major adverse cardiac events (respectively, hazard ratio = 0.28, 95% confidence interval 0.11-0.74 and hazard ratio = 0.33, 95% confidence interval 0.15-0.73).</p><p><b>Conclusion:</b> Our study on the initial phase of OPCAB adoption suggests a benefit on midterm outcome from surgery performed by a high-volume surgeon.</p> ER -
