Summary
Myocardial revascularization without cardiopulmonary bypass (CPB) using arterial conduits is feasible and safe. This approach demonstrated comparable long-term survival and event-free survival to traditional CPB methods.
Area of Science:
- Cardiovascular Surgery
- Thoracic Surgery
Background:
- Median sternotomy is a common approach for myocardial revascularization.
- Arterial conduits offer advantages for bypass grafting.
- The use of cardiopulmonary bypass (CPB) is standard but associated with potential complications.
Purpose of the Study:
- To evaluate the feasibility and outcomes of myocardial revascularization using arterial conduits without CPB via median sternotomy.
- To compare these results with traditional CPB-assisted procedures.
Main Methods:
- A retrospective study comparing 721 patients undergoing myocardial revascularization with at least two arterial conduits.
- Group A (322 patients) underwent the procedure without CPB.
- Group B (399 patients) underwent the procedure with CPB.
Main Results:
- No early deaths occurred in Group A compared to 2.3% in Group B (p < 0.02).
- Early major adverse events were significantly lower in Group A (1.2%) versus Group B (8.0%) (p < 0.001).
- Both groups showed similar long-term survival and event-free survival rates at 30 months, with high graft patency (98.4% cumulative).
Conclusions:
- Myocardial revascularization without CPB using arterial conduits is a safe and effective alternative.
- This technique achieves comparable results to CPB-assisted procedures.
- It offers potential benefits in reducing early mortality and major adverse events.
