1 Perfusion-assisted direct coronary artery bypass: selective graft perfusion in off-pump cases 
Robert A Guyton, MD, Vinod H Thourani, MD, John D Puskas, MD, Jack S Shanewise, MD, Mark A Steele, Candace L Palmer-Steele, Jakob Vinten-Johansen, PhD  The Annals of Thoracic Surgery  Volume 69, Issue 1, Pages (January 2000) DOI: /S (99)

2 Fig 1 Perfusion-assisted direct coronary artery bypass system. Aortic blood is directed from the aortic cannula (A) through the Quest MPS to the multiple perfusion set (B), and finally the proximal vein or arterial grafts (C). The vein infusion pressure is monitored by the MPS system from a feedback line (D) located at the proximal portion of the multiple perfusion set. The Annals of Thoracic Surgery  , DOI: ( /S (99) )

3 Fig 2 The changes in perfusate flow (at a constant infusion pressure) before and after initiation of nitroglycerin (100 μg/L) in 4 patients undergoing PADCAB are shown. (NTG = nitroglycerin.) The Annals of Thoracic Surgery  , DOI: ( /S (99) )

4 Fig 3 The relationship of infusion pressure (mm Hg) and perfusate flow (mL/min) during PADCAB is shown in 3 patients. The Annals of Thoracic Surgery  , DOI: ( /S (99) )
