Observe the Unexpected: A Strange History of Bioprosthesis in a Patient in Dialytic Treatment

A 73-year-old male with a history of right nephrectomy due to cancer in 1996 was referred to our hospital for dyspnea and acute chest pain. In May 2007, the Shelhigh® No-React® valved bioconduit was implanted using the Bentall-De Bono procedure due to the finding of severe aortic valve insufficiency and acute type A aortic dissection. Nine months after discharge, he was placed on chronic renal dialysis. The patient’s condition was followed carefully after being placed on dialysis, and now, thirteen years later the implanted aortic valve is still moving freely without signs of calcification.
