Summary
This study presents a standardized off-pump coronary artery bypass grafting (CABG) technique. It allows for consistent surgical outcomes without cardiopulmonary bypass, enhancing patient recovery.
Area of Science:
- Cardiovascular Surgery
- Cardiac Surgery Techniques
- Minimally Invasive Cardiac Surgery
Background:
- Off-pump coronary artery bypass (OPCAB) surgery literature has grown since 1998.
- Varying OPCAB techniques and outcomes have led to inconsistent application.
- A standardized OPCAB approach is needed for reproducible results.
Purpose of the Study:
- To describe a standardized, reproducible off-pump coronary artery bypass grafting (CABG) technique.
- To detail a method that avoids cardiopulmonary bypass conversion.
- To present a no-touch aorta strategy for graft anastomosis.
Main Methods:
- Standard median sternotomy for bilateral internal mammary artery harvesting.
- Pericardial stitches and a sling system to expose cardiac surfaces without deforming the atrio-ventricular axis.
- Apical suction device for ventricular stabilization and exposure, followed by anastomoses using free grafts to in-situ arterial grafts with a no-touch aorta technique.
Main Results:
- The described technique is straightforward and replicable.
- It allows for exposure of anterior, lateral, and inferior cardiac surfaces.
- The no-touch aorta strategy ensures free grafts are anastomosed to in-situ arterial grafts.
Conclusions:
- The standardized off-pump coronary artery bypass grafting (CABG) technique is effective and reproducible.
- This approach facilitates consistent surgical outcomes without cardiopulmonary bypass.
- The technique ensures optimal graft utilization and patient recovery.
