Abstract:
We report a case of recurrent mitral regurgitation due to calcification of the expanded polytetrafluoroethylene sutures. According to pathologic findings, it was believed that due to the dystrophic calcification of the fibrous tissue covering the expanded polytetrafluoroethylene sutures, there was increased hyalinization, leading to sclerosis and shortening of the chordae. Calcification of expanded polytetrafluoroethylene sutures after mitral valve repair is a rare complication; however, careful follow-up should be needed because such change may occur in long-term periods after implantation.
