Summary
This study presents a novel technique for myocardial revascularization of the circumflex artery without extracorporeal circulation. The method allows safe and effective coronary artery bypass surgery, improving patient outcomes.
Area of Science:
- Cardiovascular Surgery
- Cardiac Anesthesia
- Minimally Invasive Cardiac Surgery
Background:
- Coronary artery bypass grafting (CABG) traditionally relies on extracorporeal circulation (ECC).
- Revascularization of the circumflex artery and its marginal branches can be challenging.
- Developing off-pump techniques is crucial for improving patient safety and outcomes.
Purpose of the Study:
- To introduce a novel technical alternative for myocardial revascularization of the circumflex artery.
- To demonstrate the feasibility of performing this procedure without extracorporeal circulation (ECC).
- To evaluate the safety and efficacy of this off-pump approach.
Main Methods:
- A technique involving posterior pericardium stitching and heart manipulation was employed.
- A polypropylene suture and cardiac ribbon were used to expose the circumflex artery and its marginal branches.
- The procedure was performed without the use of cardiopulmonary bypass.
Main Results:
- Over a 17-year period, 609 patients underwent revascularization without ECC.
- 147 patients (24.14%) had circumflex artery revascularization using this technique.
- Serious complications occurred in 7.88% of patients, with a mortality rate of 3.44%.
Conclusions:
- The described technique allows for effective exposure and anastomosis of the circumflex artery and its marginal branches.
- Myocardial revascularization can be safely performed without ECC, maintaining hemodynamic stability.
- This off-pump approach offers a viable alternative for complete coronary revascularization.
