The Symmetry bypass system (ACS) offers a simpler, faster coronary artery bypass grafting (CABG) technique without aortic clamping. However, its graft patency is lower than standard methods, requiring careful consideration.

Area of Science:

  • Cardiovascular Surgery
  • Medical Device Technology

Context:

  • Coronary artery bypass grafting (CABG) is a common procedure for treating coronary artery disease.
  • Minimally invasive techniques aim to reduce surgical complications and recovery time.

Purpose:

  • To evaluate the safety and efficacy of the St. Jude Medical Symmetry bypass system (ACS) for proximal anastomoses in CABG.
  • To assess anastomotic patency and clinical outcomes associated with ACS use.

Summary:

  • Forty patients underwent CABG using the ACS, with 59 proximal anastomoses performed.
  • Postoperative angiography revealed a graft occlusion rate of 13.1% (5/38) in saphenous vein grafts.
  • The ACS simplifies proximal anastomosis without aortic clamping, potentially reducing embolization risk, but shows lower graft patency compared to standard suturing.

Impact:

  • The ACS provides a technique to expedite CABG procedures and minimize aortic manipulation risks.
  • Lower graft patency necessitates further investigation and discussion regarding optimal patient selection and technique refinement for ACS.
