Insights

Arterial grafts, particularly the internal thoracic artery, offer superior long-term results in coronary artery bypass grafting (CABG). Broader adoption of arterial CABG in China is recommended due to accumulating evidence and excellent clinical outcomes.

Area of Science:

  • Cardiovascular Surgery
  • Thoracic Surgery
  • Vascular Surgery

Background:

  • The choice of graft conduit is a critical, debated aspect of coronary artery bypass grafting (CABG).
  • Arterial grafts are recognized for superior biological properties and long-term patency compared to traditional venous grafts.
  • The internal thoracic artery is established as the gold standard graft in CABG based on extensive clinical evidence.

Purpose of the Study:

  • To review the evidence supporting arterial grafts in CABG.
  • To discuss the benefits and challenges of multi-arterial and total-arterial CABG.
  • To advocate for the increased application of arterial CABG in China.

Main Methods:

  • Review of clinical observations and randomized clinical trials over two decades.
  • Analysis of published guidelines and expert consensus statements.
  • Evaluation of trends in coronary surgery and graft selection.

Main Results:

  • Multi-arterial and total-arterial CABG significantly enhance long-term patient survival.
  • The internal thoracic artery demonstrates excellent long-term patency and biological characteristics.
  • Despite technical challenges and concerns of sternal complications, arterial grafting is increasingly favored globally.

Conclusions:

  • Arterial coronary artery bypass grafting offers superior long-term outcomes and should be more widely implemented.
  • The accumulation of evidence and excellent long-term clinical results support broader application of arterial CABG in China.
  • Continued quality improvement in coronary surgery in China necessitates wider adoption of arterial grafting techniques.
