Summary
This study on ascending aortic replacement using the button technique shows significantly improved long-term survival rates. The standardized surgical approach enhances patient outcomes for aortic disease and Marfan syndrome.
Area of Science:
- Cardiovascular Surgery
- Thoracic Surgery
- Aortic Surgery
Context:
- Ascending aortic replacement is a complex procedure.
- The button technique for coronary reimplantation has evolved.
- Long-term outcomes for aortic root and ascending aorta pathologies require continuous evaluation.
Purpose:
- To evaluate the long-term outcomes of ascending aortic replacement using the button technique.
- To assess survival rates and complications associated with this surgical approach.
- To compare current results with previous institutional data.
Summary:
- A 20-year study (1980-2000) analyzed 150 patients undergoing ascending aortic replacement with the button technique.
- The procedure involved valvular conduit replacement and coronary reimplantation.
- Associated conditions included annulo-ectasia, Marfan syndrome, and aortic dissection.
Impact:
- The study reports significantly improved actuarial survival rates (85% at 10 years, 60% at 20 years) compared to previous data.
- Low operative mortality (0.6%) and acceptable rates of thrombosis, embolism, and hemorrhage were observed.
- The adoption of a single, standardized operative technique and improved myocardial protection strategies are credited for the enhanced prognosis.
