Abstract Background: The use of computer-animated surgical instruments for various cardiac operations has been shown to be feasible, but to date, the available information regarding the operative and technical details of these procedures is still inadequate. Methods: We used the Zeus™ (Computer Motion Inc., Goleta, Calif, USA) telemanipulation system to perform the internal mammary artery (IMA) takedown in 56 patients, in 12 of whom we used the newest model with MicroWrist™ (Computer Motion Inc., Goleta, Calif, USA) technology. Port orientation was based on thoracic anatomy, the decisive landmarks being the mammillary line and the axillary line. The distance between ports was at least 9 cm, and the patient's arm was positioned with the left shoulder raised and angulated by not more than 90 degrees. Results: Mean setup time was 44 ± 18 minutes for the first five patients and 16 ± 7 minutes for the last five patients, with an overall average of 24 ± 12 minutes. IMA harvest time at the beginning reached a mean of 95 ± 23 minutes and decreased to 44 ± 18 minutes in the last five cases. Average IMA takedown time was 58 ± 17 minutes. The IMA was patent with a good flow in all 56 patients. Conclusions: The introduction of robotic technology into clinical routine has resulted in safe procedures with a short learning curve. However, basic training in the modality is a must in order to achieve technical excellence. (J Card Surg 2003; 18:1-5)
