Robotic coronary artery bypass grafting (CABG)--the Leipzig experience

Technical and anatomical limitations as well as human factors complicate endoscopic coronary bypass surgery. Computer-enhanced telemanipulation systems overcome some of these shortcomings by restoring the dexterity and precision of a distant operator (surgeon) within a confined space. Endoscopic coronary artery bypass grafting (CABG) has evolved from a merely experimental approach to a clinical concept. Although CABG was initially exclusively performed on the arrested heart, adjunct technologies such as endoscopic vacuum-assisted stabilizers now allow a closed-chest, beating-heart procedure. The development of anastomotic devices, and further refinements in telemanipulator technology, optical systems, and image-guided augmented-reality scenarios will greatly facilitate endoscopic bypass grafting in the future.
