Insights

This study presents a novel clampless technique for coronary artery bypass grafting in patients with calcified aorta. The Foley catheter method offers a safe and effective alternative for proximal anastomosis, achieving excellent graft patency.

Area of Science:

  • Cardiovascular Surgery
  • Surgical Innovation

Background:

  • Coronary artery bypass grafting (CABG) often faces challenges with calcified ascending aortas.
  • Standard techniques for proximal anastomosis can be difficult and risky in these cases.

Purpose of the Study:

  • To describe and evaluate an alternative clampless technique for proximal anastomosis in CABG.
  • To assess the safety and efficacy of using a Foley catheter and polypropylene suture for calcified ascending aortas.

Main Methods:

  • A novel technique utilizing a Foley catheter and polypropylene suture was employed for clampless proximal anastomosis.
  • The procedure was performed on 30 patients undergoing coronary artery bypass grafting.

Main Results:

  • The mean time for proximal anastomosis was 18.9 ± 1.3 minutes.
  • No early or late deaths were observed; stroke occurred in 2 high-risk patients.
  • At a mean follow-up of 1.6 years, graft patency was 93% with only 1 patient experiencing recurrent angina.

Conclusions:

  • This alternative clampless technique is a safe and effective approach for managing calcified ascending aortas during CABG.
  • The method demonstrates favorable outcomes, including high graft patency and low complication rates.
