Robot-Assisted Minimally Invasive Multivessel Coronary Bypass Guided by Computerized Tomography

Area of Science:

• Cardiovascular Surgery
• Medical Imaging
• Robotics in Medicine

Background:

• Robot-assisted minimally invasive coronary bypass surgery (RCAB) provides a less invasive option for multivessel revascularization.
• Accelerated patient recovery is a key benefit of minimally invasive surgical techniques.

Purpose of the Study:

• To investigate the benefits of using computed tomography angiography (CTA) to guide robotic coronary artery bypass (RCAB) procedures.
• To analyze perioperative outcomes in patients undergoing CTA-guided RCAB.

Main Methods:

• Sixty consecutive patients undergoing RCAB with preoperative CTA guidance were analyzed.
• CTA was used to determine optimal minithoracotomy incision sites and peripheral vascular cannulation.
• Perioperative parameters and early outcomes were evaluated.

Main Results:

• CTA-guided RCAB successfully revascularized an average of 2.9 vessels per patient.
• Incisional sites and cannulation strategies were effectively guided by CTA, with 46.7% requiring axillary cannulation.
• No operative mortality or cerebrovascular events occurred; one patient needed reoperation for bleeding.

Conclusions:

• Robot-assisted minimally invasive multivessel coronary bypass surgery guided by preoperative CTA is a safe procedure.
• CTA guidance in RCAB facilitates excellent surgical results and patient outcomes.
