Rerepair for recurrent mitral regurgitation due to Physio ring dehiscence.

A 57-year-old man suffered recurrent mitral regurgitation after dehiscence of a 28 mm Physio ring 3 months after initial repair. We substituted a 30 mm Physio ring in reoperation, enabling successful mitral rerepair. This case points up the need for special care to be taken in determining the size of rigid rings and suture placement deep enough in annular tissue.
