From April, 1983 to March, 1993, 63 @entity1 (pts) underwent reoperations of @entity340 at Tokyo Medical and Dental University Hospital, of which 44 pts had undergone closed mitral commissurotomy (CMC), open aortic or mitral commissurotomy (OAC or OMC) or valvuloplasty, and 17 pts had undergone aortic or mitral valve replacement ( @entity31716 or MVR). Valve replacement was performed in 59 pts (mechanical valve replacement; 42 pts, porcine valve replacement; 12 pts), and 2 pts received OMC due to @entity256 after CMC. Preoperative diagnosis included @entity256 after CMC, OMC or valvuloplasty in 43 pts, @entity409 after MVR in 10 pts, @entity2680 after @entity31716 in 1 pt, @entity1713 after @entity31716 in 4 pts (Be  het 3 pts, @entity884 1 pts). Valve replacement or valvuloplasty was done for another valves in addition to the previously operated valve in 44 pts (72.1%), especially for tricuspid valve. @entity256 after CMC, occurred at 20.6 years after surgery, and @entity256 after OMC and valvuloplasty at 13.1 years. @entity409 after MVR occurred at 8.5 years. @entity340 of the mechanical valve was not observed. The early operative mortality after reoperations was 11.5% (7 pts) in this series. And 3 pts (4.9%) died in the late follow-up due to @entity5 in 1 pt and @entity712 in 2 pts. A first choice of mechanical valve for redo valve replacement for aortic/mitral valve, and modified @entity31716 using composite graft and proximal double fixation to the fragile annulus seemed to be satisfactory to accomplish better operative results.
