Why the study?
Recurrent mitral regurgitation due to ruptured artificial chords after transapical Neochord mitral valve repair is rare.
Recurrent severe mitral regurgitation is a rare but possible complication after transapical Neochord mitral valve repair due to detached or partially ruptured artificial chords.
Clinicians should monitor for late chord failure after Neochord; leaves open durability questions in larger cohorts.
Transapical Neochord mitral valve repair has been proven to be a technically safe procedure to correct primary mitral regurgitation (MR). Recurrent MR due to ruptured artificial chords is rare. Here, we present 2 cases of recurrent severe MR due to the detached or partially ruptured artificial chords after the Neochord procedure.
