Summary

Total arterial revascularisation, using bilateral mammary grafts and other arterial conduits, offers optimal results for myocardial revascularisation, improving survival rates. This approach enhances outcomes in coronary artery bypass surgery.

Area of Science:

  • Cardiovascular Surgery
  • Thoracic Surgery
  • Vascular Surgery

Background:

  • Arterial revascularisation has gained prominence, largely due to the routine use of the left internal mammary artery (LIMA).
  • LIMA grafting to the left anterior descending (LAD) coronary artery is crucial for successful coronary revascularisation outcomes.
  • The potential benefits of using additional arterial grafts beyond the LAD territory remain under investigation.

Purpose of the Study:

  • To evaluate the effectiveness of total arterial revascularisation strategies.
  • To determine if using multiple arterial grafts improves long-term results in myocardial revascularisation.
  • To assess the outcomes of a specific arterial grafting strategy utilizing bilateral mammary grafts and other conduits.

Main Methods:

Related Experiment Videos

  • Analysis of 2236 patients undergoing myocardial revascularisation between October 1991 and June 2000.
  • Implementation of a strategy prioritizing left coronary system arterial grafts, including skeletonized mammary conduits and Y-grafts.
  • Utilization of gastroepiploic artery in situ and radial artery grafts, connecting to the internal mammary artery to avoid aortic anastomoses.

    • Main Results:

    • 75% of patients received total arterial revascularisation.
    • Early mortality rate was 2% in the total arterial revascularisation group.
    • Survival rate at 7 years was 93% for patients undergoing total arterial revascularisation.

    Conclusions:

    • Total arterial revascularisation, particularly with bilateral mammary grafts supplemented by other arterial conduits, yields optimal results.
    • This strategy appears to provide excellent long-term survival rates in myocardial revascularisation.
    • The study supports the hypothesis that comprehensive arterial grafting enhances the quality of late results in coronary revascularisation.
