Fewer Grafts Performed in Off-Pump Bypass Surgery: Patient Selection or Incomplete Revascularization?

Completeness of revascularization, determined by comparing the number of grafts performed to the number needed, was equivalent in OPCAB and CCAB patients, and 18-month clinical outcomes were equivalent. Preferential selection of patients needing more bypass grafts to CCAB results in the lower mean number of grafts per patient with OPCAB.
