Myocardial revascularization with arterial conduits. The use of lateral costal artery

Area of Science:

• Cardiovascular Surgery
• Cardiac Surgery
• Vascular Grafting

Background:

• Complete arterial revascularization is preferred for myocardial revascularization.
• Arterial conduits offer better long-term patency rates compared to venous grafts.
• Exploring alternative arterial conduits is crucial for optimizing surgical outcomes.

Observation:

• A 54-year-old male patient underwent coronary artery bypass grafting.
• The surgical procedure utilized the right internal mammary artery (RIMA) for the right coronary artery (RCA), the left internal mammary artery (LIMA) for the left anterior descending artery (LAD), and the lateral costal artery (LCA) for obtuse marginal arteries.
• The patient experienced an uneventful postoperative recovery.

Findings:

• A 12-month postoperative coronary angiography confirmed excellent function of all arterial conduits.
• The lateral costal artery (LCA) demonstrated successful patency and suitability as an arterial conduit for myocardial revascularization.
• This case highlights the efficacy of LCA in achieving complete arterial revascularization.

Implications:

• The lateral costal artery (LCA) represents a valuable and effective additional source for complete myocardial revascularization using arterial conduits.
• Incorporating LCA into surgical planning may enhance long-term outcomes for patients requiring coronary artery bypass grafting.
• This approach broadens the options for arterial grafting in complex coronary artery disease cases.
