N2 - OBJECTIVES: The goal of this study was to assess procedural details and outcomes of repeat MitraClip therapy.BACKGROUND: MitraClip implantation is a safe and efficacious percutaneous approach to treat significant mitral regurgitation (MR).METHODS: Of 410 inoperable or high surgical risk patients treated with the MitraClip at our institution, 17 (4.1%) patients, as well as 4 patients initially treated at external institutions, underwent repeat MitraClip procedures. Mean age of the 21 patients (14 men [67%]) was 77 years; 15 patients (71%) had functional MR.RESULTS: Repeat procedures performed at a median of 6.3 months (range 0.7 to 34 months) after the index intervention were successful (discharge MR grade ≤2+) in 13 patients (62%), with a pronounced difference in success rate observed between the 13 patients with adequate leaflet insertion at the time of the repeat intervention and the 8 patients in whom loss of leaflet insertion (LLI) (leaflet tear/perforation or partial clip detachment) was present (11 of 13 [85%] vs. 2 of 8 [25%], respectively). The 21 patients were followed for a median of 8.5 (interquartile range: 2.3 to 18.6) months; 13 patients (62%), 8 with adequate leaflet insertion and 5 with LLI, died during follow-up.CONCLUSIONS: Repeat MitraClip intervention for significant recurrent MR appears to be a viable therapeutic approach in patients in whom leaflet insertion into the MitraClip is not compromised. LLI is strongly associated with repeat procedural failure.
