Abstract:
A 72-year-old woman underwent a double aortic valve replacement with the Freestyle aortic bioprosthesis and subcoronary implantation with the Mosaic mitral bioprosthesis because of rheumatic multivalvular heart disease in 2000. During her annual follow-up, her Sinotubular junction was observed to have gradually increased in diameter on echocardiography and computed tomography. Therefore, 9 years after surgery we performed a reoperation for severe aortic regurgitation. Intraoperatively, the stentless bioprosthesis was found to be structurally intact. We believe that the dilation of the Sinotubular junction associated with a stentless bioprosthesis in the subcoronary position have caused her severe aortic regurgitation.
