Long-term outcomes after mitral ring annuloplasty for degenerative mitral regurgitation: Duran ring versus Carpentier-Edwards ring.

Abstract

Although the Duran and Carpentier-Edwards rings showed comparable long-term outcomes in terms of LV function, MR recurrence, survival and reoperation, a greater tendency towards MS development was observed with the Duran ring, this being most likely due to late pannus formation.
