Summary
The modified Bentall procedure using the button technique is a safe and effective method for aortic root replacement, demonstrating good long-term survival rates and manageable reoperation needs in a 15-year study.
Area of Science:
- Cardiovascular Surgery
- Thoracic Surgery
- Aortic Surgery
Background:
- The Bentall procedure is a standard for aortic root replacement, but postoperative bleeding remains a challenge.
- Modifications like the "button technique" aim to improve outcomes.
Purpose of the Study:
- To evaluate the safety and effectiveness of the modified Bentall procedure with the button technique.
- To assess long-term outcomes including survival and reoperation rates.
Main Methods:
- Retrospective study of 112 patients undergoing the Bentall procedure with the button technique (2005-2020).
- Comparison of outcomes between commercially available and self-assembled composite grafts.
- Evaluation of safety (postoperative complications) and long-term outcomes (survival, reoperation-free survival).
Main Results:
- Overall survival was 86.1% at 5 and 10 years; reoperation-free survival was 83.4% at 5 years and 72.6% at 10 years.
- In-hospital mortality was 2.7%.
- Common indications included ascending aortic aneurysm, aortic dissection, and Marfan syndrome.
Conclusions:
- The Bentall procedure with the button technique is a safe and effective surgical option for aortic root replacement.
- Further research is needed to enhance the procedure's feasibility and effectiveness.
