AbstractThe recognition of the significant advantages of minimizing surgical trauma has resulted in the development of minimally invasive surgical procedures. Endoscopic surgery confers the benefits of minimally invasive surgery upon patients, and surgical robots have enhanced the ability and precision of surgeons. Consequently, technological advances have facilitated totally endoscopic robotic cardiac surgery, which has allowed surgeons to operate endoscopically, rather than through a median sternotomy, during cardiac surgery. Thus, repairs for structural heart conditions, including mitral valve plasty, atrial septal defect closure, multivessel minimally invasive direct coronary artery bypass grafting and totally endoscopic coronary artery bypass graft surgery (CABG), can be totally endoscopic. On the other hand, general anesthesia remains a risk in patients who have severe carotid artery stenosis before surgery, as well as in those with a history of severe cerebral infarction or respiratory failure. In this study, the potential of a new awake CABG protocol using only epidural anesthesia was investigated for realizing day surgery and was found to be a promising modality for ultra-minimally invasive cardiac surgery. We herein review robot-assisted cardiac surgery and awake off-pump coronary artery bypass grafting as ultra-minimally invasive cardiac surgeries.
