Abstract
Nearly all surgical disciplines have developed endoscopic operations over the last 2 decades that have become the standard of care. In cardiac surgery and specifically for coronary artery bypass grafting (CABG), the adoption of minimally invasive techniques was challenging for the following reasons: First, most procedures are already complex, and endoscopic approaches further increase the degree of complexity; second, the cardiac surgery community had until recently no endoscopic surgical tradition; and finally, early attempts to perform CABG with the use of conventional thoracoscopic instrumentation failed completely.1 Cardiac surgeons have standardized open operations for acquired heart disease, and despite low mortality and excellent results, CABG outcomes are heavily scrutinized. Consequently, the bar has been raised for any new competing technology, which has slowed its adoption. Robotic surgical technology was developed with the idea of performing remote operations and procedures in difficult spaces. These machines allow surgical maneuvers to be performed by instruments on robotic arms that are controlled by the operator from a console situated away from the operating table. This technology is well suited for completely endoscopic suturing inside the chest. In 1998, Loulmet et al2 performed the world's first totally endoscopic coronary artery bypass (TECAB) procedure using robotic assistance. The patient who received a single left internal mammary artery (IMA) to left anterior descending artery graft remains alive and free from angina 12 years postoperatively. During subsequent years, development has been slow but significant. TECAB developed from a single-vessel procedure to complex endoscopic robotic multivessel revascularization (Figure 1). The third generation of surgical telemanipulators is now available, with technological improvements in the areas of high-definition video, robotic arm mobility, instrument reach, surgeon comfort, and capability for intraoperative surgical endoscopic teaching with a dual-console system.3 Figure 1.
