[A case of major dehiscence of a prosthetic aortic valve]

A case, 48-year-old man, was presented of dehiscence of an aortic Björk-Shiley prosthesis, which was diagnosed by pendular movement of prosthetic mount in cineangiographic finding. Emergent operation of Re-AVR was performed successfully. Valve dehiscence should be confirmed by cineangiographic examination, in case of progressive congestive heart failure combined with traumatic hemolytic anemia and high grade fever suggestive of prosthetic valve endocarditis.
