Figure 4. Change in MR severity at rest and NYHA functional class pre-MitraClip implantation, at discharge and at 1-year follow-up in patients with dynamic severe MR (n = 44) and severe MR at rest (n = 167). MR severity at rest and NYHA functional class improved following MitraClip independent of the presence of dynamic MR. MR: mitral regurgitation; NYHA: New York Heart Association; PMVR: percutaneous mitral valve repair
