Although the freestyle aortic root bioprosthesis offers excellent clinical outcomes, the surgical mortality after reoperation is extremely high compared to that after aortic valve replacement and Bentall operation. We have described a surgical technique for structural valve deterioration of the freestyle bioprosthesis with a small aortic annulus. Modified Konno procedure with anterior aortic annular enlargement was indicated to repair the tentative pseudoaneurysm. Postoperative image of the aortic root showed a successful reconstruction without stenosis. This approach was found to be safe and efficient in this complicated reintervention case.
