Role of the learning curve in very high–risk patients treated with MitraClip device for functional mitral regurgitation: a single-centre experience

“Learning curve and procedural volume in mitral valve disease”

“…Moreover, TMVR permit to refine the intervention using different devices in a one-or twostep procedure to associate the benefit of chordal repair, edge-toedge, or annuloplasty technique. 29,30 Mitral transcatheter interventions are affected by an unavoidable learning curve, as evidenced by the results published about Mitraclip [31][32][33][34] or Neochord. 35 Unlike surgery, the learning curve is influenced not only by operators' experience but also from preoperative and intraoperative cardiac imaging assessments, increasing the need for dedicated highly specialized mitral valve centers.…”
