Surgical Steps Toward Complete Revascularization in Off-Pump Coronary Bypass

Surgical techniques aimed at complete myocardial revascularization without the use of cardiopulmonary bypass are described. Between January 1998 and June 2000, coronary artery bypass was performed in 3,003 patients; an off-pump tech- nique was used in 676 and cardiopulmonary bypass was employed in 2,327. Patient characteristics, demography, and preoperative risk factors of the two groups were compared retrospectively, and differences in operative variables and postoperative outcomes were analyzed. Using a commercially available suction stabilization device and the surgical and anesthetic techniques described herein, off-pump coronary revascularization was accomplished with results comparable to the on- pump approach.
