Double-vessel revascularization using a composite graft approached from small left thoracotomy

Area of Science:

• Cardiovascular Surgery
• Minimally Invasive Procedures
• Vascular Grafting

Background:

• Minimally invasive direct coronary artery bypass (MIDCAB) typically involves single-vessel revascularization through a small incision.
• The left internal mammary artery is commonly used for bypass to the left anterior descending artery.
• Limited operating fields historically restrict MIDCAB to single bypass procedures.

Observation:

• This study presents two cases of successful double-vessel revascularization using a minimally invasive approach.
• The procedure was performed via a left small thoracotomy, avoiding sternotomy.
• A composite graft, combining the internal mammary artery and the inferior epigastric artery, was utilized.

Findings:

• Successful double-vessel revascularization was achieved in both presented cases.
• The composite graft allowed for bypass to both the left anterior descending artery and the diagonal artery.
• This demonstrates the feasibility of extending MIDCAB beyond single-vessel bypass.

Implications:

• This technique expands the application of minimally invasive coronary artery bypass surgery.
• It offers a less invasive alternative for patients requiring revascularization of multiple coronary vessels.
• Further research may validate this approach for a broader patient population seeking reduced surgical trauma.
