Comparison of effectiveness and survival after the MitraClip or Carillon procedure for severe functional mitral regurgitation: a single-center retrospective analysis.

Initially, the degree of FMR was reduced in the MC group from 2.9 ±0.3 to 1.7 ±0.7 and from 2.7 ±0.5 to 2.1 ±0.7 in the CS group, within and between groups < 0.01. Within 6 months, FMR remained reduced in the MC group (1.83 ±0.6) and CS group (2.1 ±0.7). One-year survival was 34.8% in the MC group and 54.8% in the CS group ( = 0.663). Median long-term survival was 1.66 years in the MC group and 3.92 years in the CS group, log rank = 0.001.
