title: [Prosthetic valve endocarditis after double valve replacement].
abstract: This is a report of a patient who underwent re-AVR due to prosthetic valve endocarditis after double valve replacement (MVR, AVR). A 54-year-old female was admitted to other hospital on April 14, 1990, because of high fever, progressive anemia, and cardiomegaly. The patient was hospitalized to our department urgently with the diagnosis of prosthetic valve endocarditis. Arterial blood culture grew methicillin-resistant Staphylococcus epidermidis. Echocardiography showed a vegetation at the disc of the mechanical valve in the mitral position, but we could not find any vegetation or thrombus there at the reoperation, and the aortic mechanical valve seemed to be intact. Signs of inflammation continued to be positive after reoperation. On the 33rd hospital day, a diastolic murmur was heard, and emergency cardiac catheterization was done. Detachment of the prosthetic aortic valve and rupture of the sinus of Valsalva due to mycotic aneurysm, and the dissection of the aorta had occurred. We performed re-AVR and replacement of the ascending aorta. The patient died of multiple organ failure following drug-induced hepatic failure. It is suggestive that we missed the prosthetic aortic valve endocarditis during the reoperation. Our thoughts and introspections on the echocardiographic diagnosis of the prosthetic valve endocarditis after double valve replacement were discussed.
