Context: Arterial grafts are thought to be better conduits than saphenous vein grafts for coronary artery bypass grafting (CABG) based on experience with using the left internal mammary artery to bypass the left anterior descending coronary artery. The efficacy of the radial artery graft is less clear.
Objective: To compare 1-year angiographic patency of radial artery grafts vs saphenous vein grafts in patients undergoing elective CABG. Read More

Objective: The aim of our study was to evaluate the long-term outcome of patients exclusively undergoing total arterial revascularization off-pump coronary artery bypass grafting and to compare the performance of the radial artery and the right internal thoracic artery as a second conduit.
Methods: We studied a consecutive series of 1700 patients undergoing off-pump coronary artery bypass grafting, receiving a radial artery or right internal thoracic artery as a second graft for total arterial revascularization, between 2003 and 2010. A total of 1447 patients (85. Read More

Objective: Despite profound differences in the neurohumoral milieu in patients undergoing on-pump and off-pump coronary artery bypass grafting, it is uncertain how this affects graft blood flow.
Methods: We prospectively recorded intraoperative transit-time flow measurements (MediStim BF 2004; MediStim AS, Oslo, Norway) in all internal thoracic artery, radial artery, and long saphenous vein conduits in patients undergoing off-pump and on-pump bypass grafting by a single surgeon. We calculated a flow/pressure ratio as a ratio of mean graft flow to mean arterial pressure for all the conduits just before chest closure. Read More

Objective: In the Randomized On/Off Bypass (ROOBY) Trial, the efficacy of on-pump versus off-pump coronary artery bypass grafting was evaluated. This ROOBY Trial planned subanalysis compared the effects on postbypass patient clinical outcomes and graft patency of endoscopic vein harvesting and open vein harvesting.
Methods: From April 2003 to April 2007, the technique used for saphenous vein graft harvesting was recorded in 1471 cases. Read More
