Abstract
- We experienced a casts of prosthetic mitral paravalvular leak after redo DVR. As far as nonstructural dysfunction is concerned, the prosthetic paravalvular leak is not the result of prosthetic valve endocarditis, but is due to technical difficulties at the time of operation, either residual calcification or poor native tissue. Occasionally paravalvular leaks, particulary around mitral prostheses, may be silent. Paravalvular leaks are usually repaired when there is significant anemia or hemodynamic compromise. At reoperation, some of theses leaks can be repaired simply by patch losure around the paravalvular leak without placing additional suture or explanting the valve.
