Robotics and coronary artery surgery.

Significant progress in cardiac surgery, and specifically the surgical management of coronary artery disease, has been due in large part to enabling technology. Robotic systems have been recently developed and refined for use in cardiac surgery to facilitate, among other procedures, a totally endoscopic approach to coronary artery bypass surgery. These systems enhance precision through endoscopic approaches by specifically addressing the inherent limitations of conventional endoscopic coronary microsurgical instrumentation via computerized, digital interface, telemanipulation technology. With a combined experience of 125 patients, several groups have independently demonstrated the clinical feasibility of totally endoscopic coronary artery bypass with two commercially available robotic telemanipulation systems. Additional enabling technology is needed to overcome the challenges currently limiting development and widespread application of totally endoscopic off-pump multivessel coronary artery bypass surgery.
