Background:
In the redo aortic valve replacement (AVR), removal of the previously implanted damaged prosthesis may result in a native aortic annulus defect, making it difficult to reimplant a stented prosthesis. The Solo Smart valve, a relatively new stentless bioprosthesis, is designed for the supra-annular implantation into the wall of the sinus of Valsalva and may be a useful alternative to redo-AVR.
Case Report:
We report a successful case of redo-AVR using the Solo Smart valve.
Conclusion:
The unique feature of the Solo Smart valve is the supra-annular implantation procedure in the sinus of Valsalva without annular stitches. This bioprosthesis can be a useful alternative for redo-AVR in patients with a defect of the native aortic annulus.
