Key result
Repeat MitraClip procedures for severe recurrent mitral regurgitation due to partial clip detachment stabilized the detachment and improved MR grade in all 4 cases.
Why the study?

Does repeat MitraClip improve MR grade in patients with early recurrent severe MR due to partial clip detachment?
Repeat MitraClip is feasible and can improve MR grade in early recurrent MR due to partial clip detachment, though those with paracommissural MR may not be ideal candidates.
May support repeat MitraClip in select recurrent MR cases; hypothesis-generating and requires prospective validation before practice change.
Treatment for recurrent mitral regurgitation (MR) after MitraClip therapy remains a challenging issue. This study reports the efficacy of repeat MitraClip therapy for recurrent MR during the early phase after the index MitraClip procedure. We present a case series of four consecutive patients who underwent repeat MitraClip procedures for severe recurrent MR during the early phase. Partial clip detachment (PCD) was the suspected cause of recurrent MR in these cases. All patients received additional clip(s). PCD could be stabilized and MR grade improved in all cases compared with that before the second procedure. Repeat MitraClip procedures for recurrent MR due to PCD are feasible during the early phase. However, patients having PCD with paracommissural MR may not be good candidates for repeat MitraClip.

Hachinohe et al. (2017) conducted a case report in Severe recurrent mitral regurgitation (n=4). Repeat MitraClip procedure was evaluated on MR grade improvement and partial clip detachment stabilization. Repeat MitraClip procedures for severe recurrent mitral regurgitation due to partial clip detachment stabilized the detachment and improved MR grade in all 4 cases.
