Avoiding aortic clamping during coronary artery bypass using an automated anastomotic device

In its current application, off-pump coronary artery bypass grafting (OPCAB) requires clamping of the aorta to perform the proximal anastomosis. One of the important theoretical advantages of OPCAB is to avoid the undesirable effects of cross-clamping of the aorta. We report our early experience with a technique of no aortic clamping using the St. Jude aortic connector system in 11 patients.
