Correspondence Response to Letters Regarding Article, “Should Off-Pump Coronary Artery Bypass Grafting Be Abandoned?” I thank the authors for their comments regarding my recent clinical review.1 All the authors commented on the reduced incidence of stroke with the use of techniques that avoid aortic manipulation. However, this can be achieved with both on-pump and off-pump coronary artery bypass (OPCAB) techniques. Edelman and colleagues are correct in stating that large trials comparing on-pump and OPCAB have not reported the incidence of aortic side-biting clamp techniques. Our own incidence of perioperative strokes has decreased to
