Repair of Paravalvular Leak at Mitral Position after Redo DVR

승모판막 재치환술후 발생한 판막주위 누출 치험 1례

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.

승모판파 재치환술후 발생하는 판막주위 누출은 판륜 주위에 잔촌하는석회화나 약한 판륜조직에 의해서 발생한다. 이는 임상적으로 혈관내 용혈성 빈혈이나 혈역학적 인 변화를 야기하는데 서서히 나타나기 때문에 외래에서의 추적 관찰이 중요하다. 재치환한 판막의 구조적인 변화가 없고 비교적 적은 부위의 판막주위 누출이고 기존의 판륜이 약해져 있는 경우에는 새로이 판막을 치환하는 것보다 단순히 패취로 복구시 킬 수 있다.
