Which statement is true regarding robotic port-access coronary bypass grafting with a left mini-thoracotomy?

• A. It requires hypothermic cardiac arrest
• B. It involves sternotomy
• C. It does not require sternotomy
• D. It eliminates the need for one-lung ventilation

Answer: (C)

This approach achieves coronary revascularization through a small left chest incision with robotic assistance, avoiding a full splitting of the sternum. Because the sternum is not divided, there is no sternotomy required. Exposure is gained through a left mini-thoracotomy with ports for the robot, and the left internal mammary artery is harvested through this chest wall access to create grafts to the coronary targets. The technique often uses single-lung ventilation to deflate the left lung and provide a clearer operative field, so the idea that one-lung ventilation is eliminated isn’t correct. Hypothermic cardiac arrest isn’t a defining feature of this method either, since some cases use beating-heart techniques or off-pump or alternative perfusion methods depending on the center. Thus, the statement that it does not require sternotomy is the accurate one.
