Summary

Surgical repair of complex left main coronary artery (LMCA) stenosis is challenging. A novel technique involving great vessel transection allows heart rotation for safer, more precise LMCA patch repair, ensuring physiologic antegrade flow.

Area of Science:

  • Cardiovascular Surgery
  • Cardiac Surgery Techniques
  • Coronary Artery Disease Management

Background:

  • Direct surgical repair of left main coronary artery (LMCA) stenosis, particularly with complex or extensive atheromatous lesions, presents significant technical challenges.
  • Traditional surgical approaches may be limited in achieving optimal repair outcomes for these intricate cases.

Observation:

  • Complete transection of the great vessels enables heart rotation, exposing the cardiac base for improved surgical access.
  • This maneuver facilitates a safer, more precise, and expeditious patch repair of the LMCA.

Findings:

  • The described technique allows for easy extension of the LMCA arteriotomy beyond the bifurcation as needed.
  • Successful application in three consecutive patients demonstrates the feasibility and efficacy of this approach.

Implications:

  • This surgical strategy offers a viable solution for restoring physiologic antegrade flow in patients with complex atheromatous LMCA lesions.
  • It provides surgeons with an alternative method to enhance repair safety and precision in challenging LMCA stenosis cases.
