D for the Veterans Aff airs Randomized On/Off Bypass (ROOBY) Study Group: On-pump versus off-pump coronary artery bypass surgery.

The presence of occlusive disease of the subclavian artery (SCA) proximal to the origin of the internal thoracic artery (ITA) influences the operative strategy and the outcome of coronary artery bypass grafting (CABG). Of 780 patients who underwent CABG, concomitant SCA occlusive lesions were reconstructed in 13 patients (nine males, four females). The affected SCAs were left-sided in 11 patien...

Graft patency and completeness of revascularization are major determinants of long-term outcome following coronary artery bypass graft (CABG) procedures (1,2). Even though the results of percutaneous coronary intervention are routinely assessed with on-table X-ray angiography, the patency of grafts is not routinely determined during either on-pump (ON-CABG) or off-pump (OP-CABG) revascularizati...

one of the most common complications of operation and anesthesia is shivering. the purpose of this study was to compare the effectiveness of ondanseton and meperedine in preventing shivering after off-pump coronary artery bypass graft (opcab). in this double-blind randomized clinical trial, the sample consisted of 90 patients, who were candidates of cabg under general anesthesia. these patients...

BACKGROUND We investigated the impacts of flow demand and native coronary stenosis on graft flow and patency. METHODS We reviewed the angiograms of 549 bypass grafts in 301 patients who underwent off-pump coronary artery bypass grafting since 2007. Grafts consisted of 237 internal thoracic artery to left anterior descending artery; 97 internal thoracic artery and 52 saphenous vein grafts to l...

in patients requiring coronary artery bypass grafting (cabg), usually at least one of the internal mammary arteries is used. this study evaluates the degree of atherosclerotic involvement of the internal mammary artery (ima) in patients undergoing cabg. during two months period, 79 patients (66 male and 13 female with a medium age of 58 years) undergoing myocardial revascularization had a biops...
