Area of Science:

  • Cardiovascular Surgery
  • Surgical Instrumentation

Background:

  • Coronary artery bypass grafting (CABG) requires optimal surgical exposure.
  • Accessing posterior and inferior coronary arteries can be challenging.

Purpose of the Study:

  • To introduce a novel retractor for enhanced surgical visualization during CABG.
  • To evaluate the efficacy of the new retractor in facilitating complex anastomoses.

Main Methods:

  • Development of a retractor constructed from three woven Teflon tapes.
  • Application of the retractor during coronary artery bypass grafting procedures.

Main Results:

  • The Teflon tape retractor allows for significant counterclockwise cardiac rotation.
  • Excellent exposure of the posterior and inferior coronary artery systems was achieved.
