[Robot-assisted Coronary Artery Bypass Grafting]

Area of Science:

• Cardiovascular Surgery
• Minimally Invasive Surgery
• Robotic Surgery

Background:

• Robot-assisted surgery is advancing coronary artery bypass grafting (CABG) techniques.
• Procedures include internal thoracic artery (ITA) harvesting and totally endoscopic coronary artery bypass grafting (TECAB).
• Minimally invasive approaches offer reduced trauma, fewer complications, and faster recovery.

Purpose of the Study:

• To review the applications and challenges of robot-assisted coronary surgery.
• To highlight the potential of robot-assisted minimally invasive direct coronary artery bypass grafting (ThoraCAB).
• To discuss the current regulatory status of TECAB in Japan.

Main Methods:

• Review of current robot-assisted surgical techniques for coronary artery bypass.
• Discussion of advantages and limitations of TECAB.
• Analysis of regulatory approval for robot-assisted cardiac surgery in Japan.

Main Results:

• Robot-assisted surgery enables ITA harvesting and TECAB, including multivessel grafting.
• TECAB presents challenges, particularly the narrow surgical field in Japanese patients.
• Robot-assisted cardiac surgery for structural heart disease is approved in Japan, but TECAB is not.

Conclusions:

• Robot-assisted coronary surgery provides significant benefits in minimally invasive cardiac procedures.
• Further development and adaptation are needed for widespread TECAB adoption in Japan.
• Regulatory approval is a key factor for the integration of advanced robotic cardiac procedures.
