Randomized Controlled Trial Clinical Trial
A comparison of ischemic preconditioning versus terminal warm cardioplegia with controlled reperfusion in open heart operation.
The purpose of this study was to evaluate the effects of three different methods of cardioprotection in patients undergoing valve replacement. ⋯ Terminal warm cardioplegia with controlled aortic root reperfusion and ischemic preconditioning equally improve cardiac function and reduce the requirement of inotropic agents in patients undergoing valve replacement.

The purpose of this study was to investigate the influence of coronary artery bypass grafting on the degree of stenosis of the native coronary artery. ⋯ Coronary artery bypass grafting with saphenous vein grafts may result in progression of stenosis of the recipient coronary artery. This is less likely after coronary artery bypass grafting with internal thoracic artery grafts. This difference may be due to the ability of the pedicled internal thoracic artery graft to regulate flow. Thus competitive flow in the native coronary artery is minimized. This has significant clinical implications.
