Abstract

Background: Hemodynamic stability during cardiac manipulation for complex, multivessel off-pump coronary artery bypass grafting (OPCAB) remains problematic. Methods: A servo-controlled pump has been utilized to deliver warm whole blood to coronary grafts prior to construction of proximal anastomoses. Results: This technique may avoid detrimental hemodynamic decompensation, which may accompany regional coronary ischemia during cardiac displacement. It may also allow precise infusion of supplemental additives leading to coronary vasodilatation, myocardial resuscitation, and enhancement of myocardial contractility. Conclusion: In this report, three complex OPCAB cases are described which were successfully performed with active graft perfusion and which might not otherwise have been technically feasible by conventional OPCAB techniques.
