Abstract:
Owing to development of device technology, off-pump coronary artery bypass grafting (OPCAB) has become a safe, reproducible and reliable procedure. Surgeons must understand the advantages and limitations of each device and select appropriate devices in individual case to avoid device-related complication and a waste of cost. The directions and pitfalls of heart positioners, stabilizers and proximal anastomotic devices were described. With the improved heart positioners and stabilizers all coronary targets have been well visualized and accessible, maintaining hemodynamic stability. Automated proximal anastomotic devices and proximal anastomotic assist devices have reduced the occurrence of cerebral complications compared with the side-clamp of the ascending aorta. The appropriate use of devices in OPCAB would be a promising and cost-effective procedure for revascularization of ischemic heart disease.
