Summary
A novel surgical technique addresses aortic root and ascending aorta aneurysms, enabling stentless valve prosthesis implantation. This method reconstructs the aortic root and sinotubular junction, improving prosthesis durability.
Area of Science:
- Cardiovascular Surgery
- Aortic Aneurysm Repair
- Prosthetic Valve Implantation
Background:
- Aortic root and sinotubular junction dilatation, along with ascending aorta aneurysms, are contraindications for stentless valve prostheses.
- Modified aortic geometry can lead to aortic incompetence and premature prosthesis failure.
Purpose of the Study:
- To present a surgical technique for aortic root reconstruction enabling stentless valve implantation in patients with ascending aorta aneurysms.
- To achieve sinotubular remodeling and satisfactory stentless valve implantation.
Main Methods:
- A tubular graft replaces the ascending aortic aneurysm, facilitating sinotubular remodeling.
- The native aorta is inserted into the vascular prosthesis at the sinotubular junction and wrapped to prevent commissure spreading.
- Vascular and valve prosthesis sizing is based on annular diameter.
Main Results:
- The technique was used in 6 patients since October 1999.
- Good results were achieved in all operated patients.
Conclusions:
- This surgical technique allows for successful sinotubular remodeling and stentless valve implantation in the presence of ascending aorta aneurysms.
- The method offers a viable solution for patients with complex aortic pathologies previously considered contraindications for stentless valves.
