Abstract:
The paravalvular leak after redo mitral prosthetic valve replacement is rare but serious complication when it does happen. This condition should be corrected surgically to increase life span and improve symptoms. But simple closure or patch closure of paravalvular leak are not effective in cases of weak annulus or broad defect. We report 3 cases of trido mitral valve replacement using mechanical valve with its sewing ring expanded by a collar of Dacron sheet. The prosthetic sewing ring is anchored on the weak mitral annulus with multiple interrupted sutures, while the Dacron collar is contineuously sutured to the left atrial wall for blood tight sealing. All of the three cases showed event free postoperative course.
