- Abstract: A 65-year-old male was diagnosed with severe aortic stenosis with an indication for surgery and referred to our department. The patient opted for aortic valve replacement using a bioprosthesis. Due to the patient's relatively small native aortic valve area, a concurrent root dilatation maneuver (Bo Yang method) was performed to prevent patient-prosthetic mismatch and to allow for the implantation of a sufficiently larger bioprosthesis, facilitating the valve-in-valve procedure. The successful implantation of an Inspiris 25-mm bioprosthesis was achieved. Post-operative 3D-computed tomography revealed no tilting or misalignment of the bioprosthesis, and a properly sized, undistorted Valsalva sinus was observed. Aortic valve replacement using the Bo Yang root enlargement technique is considered a promising alternative for relatively younger patients requiring aortic valve intervention.
