A renaissance in cardiac surgery has begun. The early clinical experience with computer-enhanced telemanipulation systems outlines the limitations of this approach despite some procedural success. Technologic advancements, such as the use of nitinol U-clips (Coalescent Surgical Inc., Sunnyvale, CA) instead of sutures requiring manual knot tying, have been shown to decrease operative times significantly. It is expected that with further refinements and development of adjunct technologies, the technique of computer-enhanced endoscopic cardiac surgery will evolve and may prove to be beneficial for many patients. Robotic technology has provided benefits to cardiac surgery. With improved optics and instrumentation, incisions are smaller. The ergometric movements and simulated three-dimensional optics project hand-eye coordination for the surgeon. The placement of the wristlike articulations at the end of the instruments moves the pivoting action to the plane of the mitral annulus. This improves dexterity in tight spaces and allows for ambidextrous suture placement. Sutures can be placed more accurately because of tremor filtration and high-resolution video magnification. Furthermore, the robotic system may have potential as an educational tool. In the near future, surgical vision and training systems might be able to model most surgical procedures through immersive technology. Thus, a "flight simulator" concept emerges where surgeons may be able to practice and perform the operation without a patient. Already, effective curricula for training teams in robotic surgery exist. Nevertheless, certain constraints continue to limit the advancement to a totally endoscopic computer-enhanced mitral valve operation. The current size of the instruments, intrathoracic instrument collisions, and extrathoracic "elbow" conflicts still can limit dexterity. When smaller instruments are developed, these restraints may be resolved. Furthermore, a working port incision is still required for placement of an atrial retractor, as well as needle, tissue, and suture retrieval. With the development of specialized retractors and a delivery/retrieval port, a truly endoscopic approach will be consistently reproducible. New navigation systems and image guided surgery portend an improving future for robotic cardiac surgery. Recently, we have combined robotically guided microwave catheters for ablation of atrial fibrillation with robotic mitral valve repairs (Fig. 8). Thus, we are beginning to achieve the ideal operation, with a native valve repair and a return to normal sinus rhythm. Robotic cardiac surgery is an evolutionary process, and even the greatest skeptics must concede that progress has been made toward endoscopic cardiac valve operations. Surgical scientists must continue to critically evaluate this technology in this new era of cardiac surgery. Despite enthusiasm, caution cannot be overemphasized. Surgeons must be careful because indices of operative safety, speed of recovery, level of discomfort, procedural cost, and long-term operative quality have yet to be defined. Traditional valve operations still enjoy long-term success with ever-decreasing morbidity and mortality, and remain our measure for comparison. Surgeons must remember that we are seeking the most durable operation with the least human trauma and quickest return to normalcy, all done at the lowest cost with the least risks. Although we have moved more asymptotically to these goals, surgeons alone must map the path for the final ascent.
