[Use of the Zeus robotic surgical system for cardiac surgery].

The development of closed chest cardiopulmonary bypass systems has opened the door for totally endoscopic cardiac surgery. We used the robotic surgical system ZEUS for closure of the atrial septal defect (ASD) in three patients. Under one-lung ventilation, Port-Access cardiopulmonary bypass system of the drainage from the right internal jugular vein and the the right femoral vein and the return to the right femoral artery was started after port placement at the forth intercostal space of the right thoracic wall. ASD direct closure was achieved by using robotic surgical system ZEUS under cardiac arrest. The three patients were discharged in 7 days after the operation uneventfully. The robotic surgical system ZEUS can make cardiac surgeries less invasive than ever.
